Most of the day stays dry, but the moisture-rich air will turn out a shower or two , so pack the umbrella just in case.

Partly to mostly cloudy skies will remain Wednesday night with a low shower chance as lows slip to the mid and upper 60s.

Wednesday’s weather will be influenced by a warm front gradually progressing through New England from the southwest, bringing along warmer air, more humidity, and the chance for a shower or two in Greater Boston and most of Southern New England.

A steep southerly flow with the front will lead to plenty of clouds throughout the day, but there should be a few cracks to let the sunshine in at times. The air will have plenty of moisture so the chance of a spot shower or two will linger throughout Wednesday, morning and evening. Should more sunshine crack through the clouds then there’s the chance for an isolated downpour with the additional heating. Any precipitation should be brief.

For the commute in, it’ll be in the the mid- and upper 60s with highs building to the mid- and upper 70s. There will likely be a few spots that reach 80 around or west of I-95, wherever the sun breaks through the clouds.

You’ll notice the heavier air when you head out in the morning, with dew points around sunrise already in the low 60s. By the time you wrap up work for the day, the air will feel thick and heavy with dew points in the upper 60s.

But come Thursday, it’ll feel like Southern Florida, with dew points reaching the low 70s.

Dew points in the 70s are a precursor to a chance for a brewing storm, and New England, including Boston, will see a thunderstorm chance come Thursday afternoon and evening.

Under a blend of sun and clouds, highs will be near 90 degrees in Boston with higher readings west of the city. Mixing in very humid and moist air, the atmosphere will be primed for a classic line of thunderstorms to develop ahead of a cold front pushing into the region from the west. Some will turn severe with damaging wind gusts and heavy downpours. Boston should see any action after the commute home but that may change as we get a bit closer to Thursday afternoon.

So far so good. The trend is that high pressure will linger near New England on Saturday with it holding on long enough through Sunday. There may be a few showers well west of Boston but there’s growing optimism for a completely dry weekend.

That would snap 14 straight weekends where a trace or more rain has fallen in Boston.

Greater Boston: Mostly cloudy with highs in the upper 70s. A spot shower is possible. Dew points to the upper 60s. Lows to the upper 60s with a lingering spotty drizzle or fog overnight.

Southeastern Mass.: Mostly cloudy with patchy fog in the morning. Clouds stick around in the afternoon with a low chance of a sprinkle. Highs to the low 70s. Dew points to the low to mid-60s. Staying mostly cloudy at night with lows to the mid-60s.

Central/Western Mass.: Chance for a quick shower under mostly cloudy skies. Highs in the upper 70s in the Berkshires and possibly breaking 80 from Worcester to Springfield. Dew points push near 70, making it feel heavy outside. Staying warm at night with lows in the mid to upper 60s with a lingering shower chance.

Cape and Islands: Mostly cloudy skies with a low chance for a sprinkle. Some early morning and late evening fog is possible. Highs to the upper 60s and low 70s. Staying partly to mostly cloudy at night with lows in the mid-60s.

Rhode Island: Mostly cloudy skies with highs in the mid-70s. Chance for a sprinkle or shower is possible. Feeling muggy. Lows in the mid-60s with mostly cloudy skies and a low shower chance.

New Hampshire: More clouds than sun as highs push to the upper 70s and low 80s. An isolated shower is possible. Mostly cloudy at night with lows in the 60s paired with an isolated shower chance.

Vermont/Maine: Mix of sun and clouds with more clouds in the afternoon. Scattered showers are possible during the day with highs in the upper 70s and low 80s. Humidity building with dew points reaching the mid and upper 60s by the afternoon.

BOSTON — Nina Kuscsik, who campaigned for women’s inclusion in long-distance running and then won the Boston Marathon the first year that they were officially allowed to enter into the race, has died. She was 86.

An obituary for the A.L. Jacobsen Funeral Home in Huntington Station, New York, said Kuscsik died June 8 of respiratory failure after a long battle with Alzheimer’s disease.

“Nina was more than a pioneer, determined women’s running advocate, and celebrated icon within the sport. To us, she was a friend who will always be remembered for her kindness, joyful laugh and smile,” the Boston Athletic Association said on Instagram.

“Nina held the distinct honor of winning the 1972 Boston Marathon, and recognized the platform that came with that triumphant moment, inspiring thousands of women to reach their own goals and finish lines in the decades since. The BAA extends heartfelt condolences to Nina’s family, friends, and all in the running community who were touched by her grace.”

According to the obituary, Kuscsik graduated from high school at 16, studied nursing for two years and received her license at 18 after petitioning to change a New York law that required nurses to be 21. She won state championships in speed skating, roller skating and cycling — all in the same year — before turning to running when her bicycle broke.

She ran the Boston Marathon four times from 1968-71 — before women were officially welcomed, a period retroactively recognized as the Pioneer Era — and then won the first official women’s race in 1972.

She was also the first woman to enter the New York race, in 1970, and was one of the “Six who Sat” – six women who refused to start the ’72 New York City Marathon for 10 minutes to protest an Amateur Athletic Union rule that the women’s race had to be separate from the men’s. She won that year and the next year as well.

She later served on AAU and USA Track and Field committees drafting rules for women’s running. Kathrine Switzer, who entered the 1971 Boston Marathon using her initials and became the first woman to official compete, called Kuscsik “one of our greatest leaders.”

“Nina was not only a champion runner, but was instrumental in the official acceptance of women and distance running because she did years of tough work of changing rules, regulations and submitting medical evidence to prove women’s capability,” said Switzer, who started alongside Kuscsik and six other women who met the qualifying time for the the 1972 Boston race.

“Eight of us registered, eight of us showed up, and all eight of us finished,” she said. “It was a stunning moment — and a blistering hot day — but appropriately enough, Nina won.”

In addition to the more than 80 marathons she ran over her lifetime, Kuscsik set the American record for the 50-mile run in 1977 and won the Empire State Building Run-Up three straight years from 1979–81.

She was inducted into the Long Distance Running Hall of Fame in 1999.

Arlo, Boston’s newly crowned Mini Master Model Builder, spent about two months crafting a replica of the Tea Party scene for LEGO’s first global competition.

His creation, which features underwater and above-water scenes, will be sent to the LEGO House in Billund, Denmark, to vie against 27 other young regional winners from Shanghai to Arizona.

The Global Mini Master Model Builder will be announced in the fall.

“I‘m very excited,” Arlo said in a recent Zoom interview from his home in Dover, N.H., his shaggy blonde hair falling over his forehead. “This means a lot to me because I’ve been building LEGOs for a long time.”

A sixth grader at Dover Middle School, Arlo started playing with LEGOs when he was a toddler and has completed more than 100 LEGO sets.

Still, he never considered entering a LEGO competition until a late February visit to the LEGO Discovery Center Boston in Somerville.

He had decided to make a hand out of LEGOs, not just any hand but “a celestial hand emerging from the depths of our ocean,” when an employee approached him.

Impressed by his work, the employee told Arlo he should enter the regional Boston Mini Master Model Builder contest.

Arlo didn’t know what it was but accepted the challenge.

“So I was like, OK, yeah sure, I’ll enter into the tournament,” he recalled. “And I entered in, and I won.”

Kaleb Thome, the LEGO master builder at the Somerville LEGO center, said he saw Arlo’s hand depiction within a couple of weeks of the deadline for the Boston competition.

“He was one of the last ones to submit,” said Thome, 26. “I immediately knew this might be the one.”

The hand was a “very mature concept,” Thome said, but was “executed really well.” As artists know well, hands are a challenge to portray, Thome said.

“It’s this hand coming up from the ocean,” Thome said. “I was like, dude, that’s a sick concept.”

For Arlo, the hand was not a painstaking endeavor; it was simply another opportunity to “create anything,” the reason he was drawn to the building blocks in the first place.

“I think the fact that I could do anything,“ his imagination would allow, Arlo said, explaining his initial interest as a toddler.

When Thome, the judge for the Boston contest, selected Arlo on March 14 over some 50 other applicants across New England, Arlo was shocked.

“I couldn’t tell if they were kidding or not,” he said. “But I was definitely excited, no matter what.”

The win made Arlo Boston’s Mini Master Model Builder and catapulted him into LEGO’s first global competition.

His work had just begun.

From late March to May 31, Arlo spent one to two days a week working in the Somerville LEGO facility on his greatest creation — the Boston Tea Party. His mom or dad would typically drive him down from New Hampshire around noon on Saturday, and Arlo would stay in his workshop until closing.

His Boston Tea Party includes sea creatures, a scene from Spongebob’s Bikini Bottom, and people throwing tea into the harbor. It’s about 10 inches by 20 inches (1 x 2 base plates in LEGO math) and even has a character named Arlo in a red shirt.

Arlo meticulously placed every piece, and Thome said its scale was “the most impressive thing.”

“How much brick and plate he was able to put down,” Thome said. “He really set out some big expectations and goals for himself, and I think he achieved them.”

Besides size, the main rule for global competition is that the building represent the city or region the builder is from.

Arlo, a lover of history LEGO sets, jumped at the opportunity.

“The fact that sometimes they can be like small, little scenes cut into history,” Arlo said of historical LEGO sets. ”So you basically have your own history book without even having to read.”

Arlo said he spent a long time coming up his idea, deciding between Paul Revere’s ride and the Boston Tea Party, he eventually landed on the Harbor scene because of its size. Once he had the idea, he started and didn’t stop.

“If I have an idea, I’m gonna just put it down,” Arlo said. “Once that’s done, I’ll just continue. So I’ll legitimately just build.”

His project will be sent to Denmark after June 30 for the LEGO masters to decide its fate. Until then, it will be on display in Somerville.

The honor of Boston’s Mini Master Builder has required some sacrifices. Arlo didn’t play lacrosse this spring to focus on the LEGO project and has been busy at school, with lot of homework in his favorite subject, science. But his mom, Lindsay Humphreys said it’s been worth it.

“It required the commitment, but knowing that it was such a big deal and probably a once-in-a-lifetime opportunity, for sure, we were supportive of it,” Humphreys said.

Outside of LEGOs, Arlo enjoys video games and playing with his dog Bruno, a beagle and pug mix called a “puggle.”

But LEGOs are his guiding passion.

He wants to be a LEGO master like Thome one day. His dream car, a Volkswagen bus, is from his favorite LEGO set.

Will he get the car one day?

“Maybe if he can get a job and work towards it,” Arlo’s mom said, drawing a grin from Arlo.
