‘Goldilocks’ trees face climate change threats; community conservation work key to protecting Vermont maple industry


FRANKLIN COUNTY– As winters warm, Vermont’s maple trees are under threat from a revolving door of future concerns and dangerous invasive species. 

“If you’re in the business of having a forest, it’s tough,” said Jason Gagne, a Highgate sugarmaker and vice president of the Franklin County Sugarmakers’ Association. 

According to the Vermont Department of Health, the state has seen an increase in temperature of four degrees in the winter and two degrees in the summer since the 1960s. As the climate shifts, spring is beginning two weeks earlier while winter is starting one week later than it was previously.

As the climate changes, species which prefer warmer areas may be drawn up into more northern, historically cooler areas as they expand their territory. Non-native species which prefer these warmer climates can move into an area, like Vermont, which does not have natural protection against these non-native species, and decimate the ecosystem. 

Invasive species can be brought by humans intentionally or unintentionally, or can be spread through migration during changing climate patterns. 

There are people monitoring the situation, however, powering through to help strengthen Vermont’s forest health. From state-level experts and specialists to conservation groups at a regional level and conservation commissions at the local level, people are working together to protect the forests.

Warming weather and maple 

Vermont has led the U.S. in maple syrup production since 1916 with only two years having been out-produced by other states. Maple production is huge economically for the state, but also culturally, as sugarmaking is often a family tradition, passed down generation to generation.  

Since the 1990s, maple syrup production has continually increased, while at the same time Vermont has become one of the fastest warming states in the U.S.

Warmer temperatures mean maple trees are beginning to have a shorter window to tap into. From 1965-2015, Vermont lost about 3.3 days of the sugar production season. This variability in winter climates and shorter sugaring seasons can cause periods of insufficient maple production and threats from invasive species. 

Mark Isselhardt, maple specialist for the University of Vermont Maple Extension, said the threats to the maple industry are multi-faceted. 

“Those conditions that encourage or discourage a good run of sap are not evenly distributed across the season,” he said. “It’s pretty random but can have a huge impact on the total yield. It can be the difference of a couple degrees that can make a big difference whether or not sap runs.”

Isselhardt said as the temperatures have warmed, he’s seen sugarmakers begin tapping trees in December and January – a month or two before the traditional sugaring season begins. 

Over the past few years, Vermont maple farmers have seen the difference between too warm a season and too cold a season. 2022, for example, was widely viewed as a strong production year, as temperatures were ideal, Isselhardt said. But in 2023, temperatures warmed up and were followed by a prolonged cold snap, which hurt the overall yield.

Gagne and many other Franklin County sugarmakers have experienced first-hand warmer temperatures impacting local maple syrup production. 

“April can be very warm and it can produce a lot of syrup or zero,” Gagne said. “This year, we made very little syrup in April. It was just too warm in March and the trees kind of shut down for us.” 

Sugarmakers have to be prepared for a random change in temperature, or a  “mother nature curveball,” he added.

Warming during the sugaring season can cause a blockage tapping the trees. The taps inside the trees create a perfect mix for a microbial environment, Isselhardt said. This activity can create a blockage which cuts off the tap and completely stops production from the tap. 

Looking into the future, Isselhardt said the growth of new maple trees could be harmed by warming temperatures.

“A sustained warmth period that promotes an early exit from dormancy and then late frosts can cause damage to young trees,” he said. “A late frost isn’t going to kill, but it will delay trees’ ability to photosynthesis and rebuild stores of energy.”

Longer-term threats are slower to play out. Vermont may have a good amount of trees that will not disappear right now, but Isselhardt said the concern is a generational shift down the line.

“Sugar maple tends to be categorized as a ‘Goldilocks’ tree,” he said. “It thrives in a specific type of soil. Some places where sugar maples are growing are not on the most ideal site, so if you combine that with some other threats you might see, over time, sugar maple struggling to thrive through individual tree growth or requirements for next-gen tree growth.”

Maple trees rely heavily on cold winters to have a competitive advantage over other species. Isselhardt said warmer temperatures could invite species both known and unknown to take advantage of the maple seeds waiting to start growing. 

Josh Halman, forest health program manager for the State of Vermont, said the warming temperatures can create a way for invasives to latch on to sugar maple trees. 

“There is a lengthening of the growing season we’ve seen in sugar maple,” he said. “Those conditions can increase success for those invasive species and further their presence in the state.”

The impact of invasive species 

Invasive species that directly attack maple trees and those which harm the forest around them are monitored closely by the UVM Maple Extension program. 

Jumping Worms, for example, while not a direct attack to maple trees, harm the ideal soil conditions the trees need to thrive and grow in. The worms, which have been seen in 12 of Vermont’s 14 counties – including Franklin County – consume organic material, like decaying leaves and twigs, making it difficult for maple seedlings to get established.”

“They change the environment in the soil to the point where sugar maple struggles to regenerate,” Isselhardt said. 

There are very few pesticide applications available for maple trees. When new invasive species show up, maple producers are going to have a difficult time controlling the fight. 

Gagne said he’s always worried about the next invasive. The elm tree has almost completely been wiped out, ash trees are falling, and Gagne said he’s worried maple is next on that list. 

“I’m very worried maple could be the next one,” he said. “There’s nothing on the radar right now, but that doesn’t mean in five years from now they couldn’t attack maple.” 

From an individual sugarmaker’s perspective, Gagne said warming temperatures and invasive species can compound stressors the trees already feel.

“Not all will survive because they are so stressed out,” he said. “If it was a dryer year and you tap it, that’s another stress, if there’s more, then the tree won’t make it.”

Maple farmers are also keeping an eye out for two other invasives: the Spotted Lanternfly and the Asian Longhorned Beetle. Both insects are attracted to sweeter saps and warmer conditions, putting maple trees as a prime point of interest. 

The Spotted Lanternfly has made it as far north as Maine, with three making it to Vermont in 2021 before being killed and yet to return. ALB is currently in quarantine in central Massachusetts where it continues to be an invasive species to the area and is under constant watch by the USDA and Vermont officials.

This past January, maple producers were told to check their trees in case of ALB infestation, but no beetles were found in the state. 

Community efforts underway

While the future may look alarming, there are ways Vermonters and maple producers can work together to help safeguard the state’s forests.

For maple producers, Isselhardt said the diversity of a forest could be important in defending sugarbushes from some impacts. 

“We know in general a more diverse forest can mitigate stressors and sugar producers can retain another 25% of non-sugar maple, which appears to be important in lessening the impacts,” Isselhardt said. “It’s not just species diversity, but also encouraging multi-age forests. Not all the same aged trees but actually encouraging complexity and so there’s a range of ages.”

A range of young, medium and old maple trees is protection in case of a disturbance. If a tree falls down or is removed for example, nothing else will be able to take advantage of an opening in the canopy if a different aged maple tree can take its place.  

With new technologies, Isselhardt said it’s important to look at the traditional sap collection methods and update them for the future. 

“That ideal sugarbush image in the past used to be really big, widely spaced trees with really nothing else around,” he said. “That made a lot of sense when you had buckets as your only means of collecting sap, but with tubing it really changes it and now you can focus more on having a more robust, resilient forest.”

Understanding where the maple industry is heading remains hard work with complex systems and modelings. Doing good work now to promote forest health for the future is important and gives the trees the best position for resisting future damage.

The Franklin County Sugar Makers Association is always watching for threats, Gagne said. Members look after each other’s backs and monitor threats. He said they are happy to continue seeing Vermont’s success at the top of the maple-producing states. 

“We’re always very active at the association level getting ahead of everything, but overall, maple is very strong in Vermont right now,” he said. 

Community efforts also play an important role in keeping Vermont’s landscape as healthy as possible. 

In Franklin County, conservation commissions in Georgia and Richford as well as other towns make efforts to remove invasive species in their respective areas, though it can be challenging to do so.

“It’s very easy to spot invasive plants once you know what they look like. In fact, once you learn about them you will see them everywhere,” Alysia Catalfamo, chair of the Georgia Conservation Commission, said. “Removing them is much harder.”

Catalfamo said the combination of physical labor and insecticide makes the removal a long process, and it makes it even harder to remove the species around town.

As a warming climate impacts Vermont, she said the foothold of invasive species in the lower parts of the state have begun moving up toward Georgia. Although they can find some nests or seed producing trees and get rid of them, the impact is already around. 

But individuals can make a difference by being vigilant and checking their properties for invasives and quickly removing them. 

The conservation commission also holds events to raise awareness and remove the invasives. As they battle an invasive plant, Buckthorn, the commission will have a Buckthorn “party” event in the fall where Catalfamo said the community is welcome to come and help pull out the plant.

Richford Conservation Commission Chair Annette Goyne agrees. She said with support from the community and town, the fight against invasives can move quicker.   

Goyne said they have seen evidence of the Emerald Ash Borer spreading around Vermont and decided early on to make an action plan. She said meeting with the Town Road Crew and selectboard, the commission was able to make swift decisions in hopes of protecting their ecosystem.

Goyne said over the winter, the road crew took down some of the trees vulnerable to the Emerald Ash Borer, mostly in South Richford, but left some remaining. 

“There are still many private landowners with healthy ash trees and younger trees, and the hope is that some will out last this invasive species and replenish our ecosystem eventually, but in most of the country, this beetle has really wiped out the ash trees, so time will tell,” she said. 

Other efforts come from conservation groups like the Missisquoi River Basin Association, which works tirelessly in their efforts across the river to keep the landscape healthy.

MRBA field coordinator Sarah Lunn said their project to fight invasive Japanese Knotweed began in 2020 and has continued since. The plant spreads so easily it is often easily seen across Route 7 in Franklin County. 

The most effective part of the removal project has been community outreach. Lunn said she works with landowners around the Missisquoi River who email her and help them learn removal and prevention methods.

“I think the number one thing about invasive work is making sure people are informed about it,” she said. “A lot of invasive work doesn’t get lots of funding for conservation so a lot of this work takes lots of volunteer work.”

Halman doubled down on that message and said one of the most important parts to creating a healthy forest is having an informed public. 

“The number one thing is education and making the public aware of the species that are out there, prevent the introduction and what to do if they find it,” he said. “It’s just as important to provide info on how to manage them when they do show up.”

Volunteer efforts do not just come from local towns and villages but also through a more statewide approach. The Forest Pest First Detectors program consists of community members around Vermont who are the first people to notice invasives and report them. 

Vermont relies on testing from inside and outside the state, while also looking towards Vermonters to help report and identify invasive species. 

The LIEP Invasive Species Program helps Vermonters locate, identify and prevent future invasive species and the public is encouraged to report an invasive species finding and location using the VT invasives reporting tool.

A Vermont couple builds an 800-square-foot home on a budget – The Boston Globe

A Vermont couple builds an 800-square-foot home on a budget – The Boston Globe


Sam Gabriels and Chrissy Bellmeyer were no strangers to living small. Before they met, Bellmeyer designed and lived in a tiny house on wheels and Gabriels spent four years living out of a van, looping the country to organize pop-up farm-to-table dinners alongside Michelin-starred chefs. So, when the couple bought a half-acre lot in Waitsfield, Vermont’s Mad River Valley in a development called the Waitsfield Ten, where neighbors help each other build, 800 square feet didn’t feel like a constraint.

Architectural designer and builder Andy White of Boreal Design started by creating a simple, 20-by-20-foot box that was drywalled, then painted, in a weekend. Inside it, White built the living spaces as independent, self-supporting platforms arranged at staggered heights. He describes the plan as a counter-clockwise spiral: Down one step from the entry into the living room, up two into the kitchen, up one more into the dining room.

The level variations define each space. “If built traditionally with two floor plates and 9-foot ceilings, the house would feel claustrophobic,” White says. “Here, you experience the full interior volume, with long sightlines from corner to corner.”

Without walls dividing the public spaces, rooms morph to fit current needs and individual elements do double or triple duty. For example, the open cubbies that store Gabriels’s vinyl collection are also perches for overflow dinner party guests in the dining room and extra seating in the living room. Initially, White worried — unnecessarily — that the living room was too small and lacked a wall for a television. The couple got a projector and screen, and noted that the deck expands the experience. The mechanicals and storage are under the floors.

Upstairs, the 8-by-12-foot space in front of the primary bedroom is both a closet/dressing area and mini lounge. In the morning, guests might wander over from the second bedroom to chat; during parties, it’s another spot to hang out. “We’re very open people, so it works for us,” Gabriels says. If things change, the couple could add standard-size French doors to hide their bed. The second bedroom, which already has a pocket door for privacy, could absorb the office nook beside it to become a larger bedroom.

The materials palette celebrates what’s commonly available: nothing is precious, everything is considered. Walls and ceilings throughout are CDX fir plywood — construction-grade sheathing that is normally hidden behind drywall. Structural fir posts, usually buried, are left exposed. The couple planed, sanded, and stained the posts and sanded all the plywood, removing lumberyard stamps. In place of galvanized joist hangers, White used inexpensive angle steel, spray-painted black. Running the length of the staircase and bracketing the bedroom thresholds, it’s the home’s signature accent. It matches the exterior siding — corrugated metal that is distinctive, inexpensive, easy to install, and low-maintenance.

Sustainability was non-negotiable. Fourteen-inch-thick, cellulose-filled walls push the dwelling past passive-house standards for insulation and airtightness. They also leave deep window sills that double as seating, plant shelves, and such. The utility bill for the all-electric home averages just over $100 per month (excluding internet).

Decor-wise, color does the talking. The bright yellow kitchen and pink-tiled bath are odes to homes that Gabriels admired in New Mexico, Oregon, and California. “We took a Pacifico beer bottle cap to Home Depot to find the right canary yellow for the kitchen cabinets,” Bellmeyer says.

The built-in daybed under the stairs increases seating in the 101-square-foot living room, as do the storage cubbies and low wall that separate it from the dining room.Ryan Bent

White says his construction methods make it easy to add onto the home, although the couple has no plans to do so. Rather, they hope to build an ADU to offer housing to others in the community. “This is a mid-income development, making it cheaper than the median house price but not attainable for everyone,” Bellmeyer says.

Meanwhile, they’re grateful for White’s unconventional approach, fulfilling their wish list within the square footage their budget allowed.

White deflects the praise back onto the couple. “The home wouldn’t have come together the way that it did for anyone else; it’s very much theirs,” he says. “Chrissy and Sam’s vision, willingness to take risks and reimagine typical rooms, informed the design more than any specific space-saving or building strategy.”

Ben & Jerry’s Foundation says it will shut down amid legal dispute with parent company – VTDigger

Ben & Jerry’s Foundation says it will shut down amid legal dispute with parent company – VTDigger

The Ben & Jerry’s Foundation says it will shut down at the end of the year after its corporate parent cut off funding and evicted its three staffers Wednesday. The move leaves $600,000 a year in grants to Vermont organizations, and 40 years of the ice cream brand’s progressive mission, hanging on a judge’s future ruling.

“This is the other foot dropping in terms of the way Magnum is trying to destroy the social values of Ben & Jerry’s,” said Ben Cohen, co-founder of Ben & Jerry’s Homemade, in an interview Wednesday.

The Vermont-based iconic ice cream brand has been in a legal fight with its parent company, The Magnum Ice Cream Co. — an ice-cream spinoff of the larger corporation Unilever — since November 2024. Ben & Jerry’s alleges that the corporation overreached its control, pushing out the CEO and interfering with the brand’s political views. The question before a judge is whether the corporate parent had the authority to reshape governance and withhold funding from the foundation. 

Amid the push-and-pull over governance, Unilever audited the foundation, which is the philanthropic arm of Ben & Jerry’s, in April 2025, finding conflicts of interest and a lack of governance and financial control.

Liz Bankowski, president of the foundation’s board of trustees, said in an interview that Unilever withheld the philanthropy’s funding late last year and ordered foundation staff to vacate its corporate office in South Burlington by July 15 because of governance issues the audit raised. This led the foundation’s leaders to join the ongoing lawsuit, fought by the ice cream brand’s independent board, in an effort to retain funding. The lawsuit is pending in the U.S. District Court for the Southern District of New York. 

While the foundation’s leadership is framing the decision to cease operations as the only option after Unilever withheld funding, an unnamed spokesperson for Magnum wrote in a statement to VTDigger that the shuttering is “entirely down to the Trustees and their decision to ignore the findings of an independent audit and failure to put in place basic good governance; much to our dismay.” 

Since the audit, the foundation has adopted a conflict of interest policy, but “the bottom line was that unless we changed our board, they were going to continue to withhold funding,” Bankowski said.  

Cohen described the audit as “a bunch of trumped-up charges.” 

“The foundation has been independently audited every year,” he said. “I think that Magnum was searching in vain for some illegal or unethical activities. I think they found none.”

Since Ben & Jerry’s sold the ice cream business to Unilever in 2000, the corporation has given $60 million to the foundation. The philanthropic arm has operated for 40 years, supporting the ice cream brand’s progressive mission by offering financial backing to social justice organizations across the country. The foundation does not have an endowment and is reliant on the funding its parent company gives annually, outlined in its merger contract.

A chunk of that funding, $600,000 a year, goes to Vermont organizations such as the immigrant farmworker rights organization Migrant Justice and the LGBTQ+ nonprofit Outright Vermont, according to foundation leaders. 

“We fill a particular niche that not a lot of other funders fill,” said Rebecca Golden, the foundation’s director of programs, who has worked at the organization for 34 years. 

Golden is one of three foundation staffers whose last day in the physical office is Wednesday, following orders from Magnum to vacate. Although Magnum did not directly address its vacate order in its statement to VTDigger, the spokesperson wrote that the foundation’s leaders recently “took the position that its staff are not Ben & Jerry’s employees, despite utilising Ben & Jerry’s offices and systems.”

Golden described the possible shutdown as an “enormous loss” that will not only affect the organizations that the foundation supports but also Ben & Jerry’s employees who “feel very proud of being a part of the foundation.”

“It’s been a really long year, so there’s been a lot of emotions — the whole gamut, as we like to say of the seven stages of grief. But I think at this point we’re sort of in the acceptance phase,” she said. 

The Magnum spokesperson indicated that the work of the foundation will continue even if its leaders decide to cease operations at the end of the year, writing that the company is “firmly committed to funding a grant-giving foundation, supported by appropriate governance controls to ensure it is living by its values.”

But Cohen is not confident that Magnum will uphold the values of the Ben & Jerry’s Foundation in the corporation’s continued philanthropic efforts. 

“What are they going to fund? I have no idea. My guess is that they would not be looking to fund entities that are opposed to the status quo,” Cohen said.

The foundation’s leaders have pointed to its support of Migrant Justice during a period when the farmworker organization was considering a boycott of Ben & Jerry’s as an example of their commitment to social justice. After immigrant farmworkers raised concerns about working conditions at farms supplying Ben & Jerry’s, the company joined a program that collaborates with farmworkers to strive for fair working conditions. 

Advertisement

Political activism has been central to the Ben & Jerry’s brand since its founding. As a part of the ongoing lawsuit, Ben & Jerry’s alleged in a May filing that Magnum has been undercutting its social justice mission in order to “censor, intimidate and purge” the company’s independent board, which Cohen said was created to defend its progressive values. 

Three of the board’s members, including one who has been an outspoken critic of Israel, were removed late last year after the parent corporation introduced a new set of governance practices. In its motion to dismiss the lawsuit, Magnum argues that it retains ultimate authority and the brand’s social mission must be nonpartisan.  

As the lawsuit awaits a decision, Cohen, who is not a part of the suit, has created a campaign to “free Ben & Jerry’s,” amassing around 160,000 signers for its petition demanding that Magnum sell Ben & Jerry’s to a “group of values-aligned investors.”   

“The very values-led business model that built Ben & Jerry’s into this amazing, phenomenal brand is the very thing that Magnum is currently destroying,” Cohen said.

Hazy, hot, and humid: Wildfire plumes give southern Vermont skies an odd glow

Hazy, hot, and humid: Wildfire plumes give southern Vermont skies an odd glow


SOUTHERN VERMONT — A thick veil of wildfire smoke high in the atmosphere is transforming the sky over our local Bennington and Windham Counties this week – casting an eerie glow, muting the sun, and leaving air quality in the moderate range – even as temperatures and humidity remain oppressive.

According to federal forecasters, the hazy and particulate-laden sky and unusual colors are the result of smoke from more than 830 active wildfires burning across Canada and northern Minnesota, funneled into New England by the jet stream and trapped over the region by stubborn weather patterns.

What people are seeing, and why the sky looks so strange

Over the course of Wednesday, residents across Southern Vermont reported the sky shifting from orangey‑yellow to umber to violet hues tinged with pink, with a yellow cast over the landscape and a deep red or dark orange sun, especially nearest to sunrise and sunset.

On a normal and clear day in Southern Vermont, tiny molecules in the atmosphere scatter mostly blue light, which is why the sky appears blue.

However, this week, the air is filled with larger particulate matter from wildfire smoke, which scatters longer wavelengths of light – oranges and reds – in a process known as Mie scattering (pronounced “mee,” and named after physicist Gustav Mie who first published the mathematical description of this weird-looking light-scattering phenomenon).

Due to Mie scattering, the sky can appear milky white, with sepia tones, or faintly pink‑violet, instead of blue. The sun may appear like a dark orange or red disk, especially when low to the horizon, and sunlight at ground level feels weaker and more filtered, as if being viewed through rose-tinted glasses. And these are the effects that we are currently experiencing.

Where the smoke is coming from, and how it travels

Federal agencies have reported that more than 800 wildfires are burning in Canada, with additional fires in northern Minnesota near the Canadian border. Many of these are large, and burning through dense boreal forests with little or no containment.

These blazes have triggered evacuations at their locales and in the surrounding areas, and are attributed to areas experiencing intensive drought.

The smoke created from these wildfires reaches Vermont through a series of atmospheric steps.

The jet stream’s “conveyor belt” of high‑altitude winds scoop up smoke from the Central Canada region and carry it southeast across the Great Lakes and into New England.

A high‑pressure “lid” forms, where a strong high‑pressure system causes air to sink (a process known as subsidence) which then presses some of the elevated smoke closer to the surface.

A stalled weather pattern can occur, where slow‑moving systems over Canada and the Northeast keep the flow of smoke aimed at the region instead of sweeping it quickly away.

These patterns mean that – even though the fires are hundreds of miles away – fine particulate matter (PM2.5) from those blazes is now suspended over Vermont and neighboring states.

Local air quality: Moderate, with cautions for sensitive groups

On Wednesday, air quality in Bennington and Windham Counties sat in the “moderate” category, with the Air Quality Index (AQI) fluctuating roughly between the low‑50s and high‑90s. This was driven primarily by PM2.5 from the presence of wildfire smoke.

In practical terms, most healthy adults can go about their normal routines outdoors. However, more sensitive groups – older adults, children, people with asthma, COPD, or heart disease – are advised to limit prolonged or heavy exertion outside, especially during the haziest periods.

Those with prolonged exposure may notice throat irritation, mild coughing, or even eye discomfort – particularly during intense exercise.

Residents can track real‑time conditions using the federal AirNow “Fire and Smoke Map” and Vermont‑specific dashboards, which show localized AQI readings as plumes shift during the day on Thursday.

How the smoke is affecting storms, heat, and humidity

The same smoke that is changing the sky’s color is also subtly reshaping the weather over Southern Vermont.

Forecasters note several key effects. These include solar dimming, where smoke particles in the upper atmosphere scatter and absorb sunlight, acting as a partial sunblock. This can shave a few degrees off daytime highs, compared with what might otherwise occur under clear skies.

It can also include “capping inversion.” By warming the air aloft, the smoke can create a “cap” – a warm layer that suppresses rising air. This can weaken thunderstorms, even when surface heat and humidity are high.

Another key effect is cloud microphysics, where extra smoke particles provide millions of tiny surfaces for water vapor to cling to, producing many “very tiny” droplets rather than fewer larger raindrops. These smaller droplets don’t fall as easily, which can reduce heavy rainfall and the actual structure of a storm.

For example, on Tuesday night, Southern Vermont sat under extremely high humidity fueled by warm southerly winds pulling tropical moisture up the East Coast ahead of a cold front. Under normal conditions, that setup could have produced stronger thunderstorms. Instead, wildfire smoke likely muted the intensity of those expected storms, leaving the region with more of a muggy “soupy” feeling than the explosive severe weather that many expected.

Short‑term outlook for southern Vermont

Through Wednesday and into Thursday, forecasters expect the following for our Southern Vermont region:

Advertisement
  • Sky conditions – Persistent haze and milky skies, with periods of thicker smoke as the plumes shift southward and then rise again. The sun may remain reddish or orange at times.
  • Temperatures and humidity – Highs in the mid‑80s, with oppressive humidity at times, especially ahead of the next cold front.
  • Air quality – AQI values are forecast to remain in the moderate range, occasionally bordering on “unhealthy for sensitive groups” during heavier smoke intrusions (these are expected through Thursday).
  • Showers and storms – As another cold front approaches us on Thursday, scattered showers are expected with isolated downpours and localized “non‑severe” thunderstorms. (Smoke may again limit storm strength somewhat.)

By Friday, higher pressure and drier air are expected to build in from the west, bringing more seasonable temperatures in the upper 70s to mid‑80s, lower humidity, and improved air quality – though some high‑level haze may linger.

For now, we will continue to look at our landscape through our “rose-colored” glasses.
