Brace yourself! It’s back to winter in Massachusetts with snow in Friday’s forecast and a deep freeze this weekend.

Friday will be mostly cloudy and cool, but temperatures will drop through the afternoon and evening, increasing the chance for snowfall.

Bitter cold weather will follow the snow with arctic air gripping the region on Saturday, Sunday, and Monday.

Latest snowfall timeline

A few ocean-effect sprinkles and flurries are possible during the day, although impacts will be low with no more than a patchy coating, Boston 25 Meteorologist Shiri Spear said in her latest forecast.

Steadier rain and snow will fill in around 4 p.m. and impact the evening commute.

“As things cool down, the chance for snow is going to grow and grow during the late afternoon and evening hours,” Spear said. “Some of the worse travel conditions are probably going to be during the evening.”

The snowfall should wrap up by midnight.

An isolated snow shower or flurries are still possible on Saturday, but most areas will be dry with more clouds than sunshine.

Expected snow totals

A widespread coating to an inch of snow is likely for much of Massachusetts.

The “jackpot” areas, including northeastern Massachusetts, the Merrimack Valley, MetroWest, and interior southeastern Massachusetts could see 1-2 inches.

“Some spots could locally go up to 3 inches,” Spear said.

Cape Cod and the Islands might be too mild for sticking, but flakes will be flying.

Arctic air arrives

Frigid temperatures with highs in the upper 20s and low 30s are on tap for Saturday.

Sunday will bring freezing sunshine with temperatures in the teens and 20s.

NANTUCKET, Mass. – Two endangered North Atlantic right whales have been spotted off Massachusetts with entanglements that could potentially be life-threatening to the massive mammals.

According to NOAA Fisheries, an aerial survey team recently spotted a pair of whales approximately 50 miles southeast of Nantucket on Dec. 9. 

The smaller of the two marine animals was first sighted in 2021 and was seen free of gear as recently as April. 

But now, the survey team said a thick rope was located over the whale’s head and back, which could cause its eventual death.

The larger whale, identified as an adult female, was last seen without gear as recently as July and, due to its size, is unlikely to be as significantly impacted as the juvenile.

“This whale has two lines exiting the left side of her mouth, with both lines extending a half to two thirds of the way down the body,” NOAA stated. “After reviewing the entanglement, NOAA Fisheries biologists have made a preliminary determination that it meets the Unusual Mortality Event criteria as a ‘morbidity’ (sublethal injury) case.”

FIRST RIGHT WHALE CALF OF SEASON SPOTTED OFF SOUTHEAST COAST

Due to conditions and the distance to shore, NOAA entanglement response teams did not mount a response but stand at the ready should the occasion arise.

The agency estimates that over 85% of right whales are entangled in fishing gear at least once during their lifetime, which can cause serious injuries.

The marine animals tend to spend most of their time off the coast of Canada and the Northeast in the western Atlantic before migrating southward for the calving season.

The right whales are considered to be the 149th and 150th documented cases in the ongoing North Atlantic right whale Unusual Mortality Event (UME), which includes dead, seriously injured or health-compromised animals.

FLORIDA IDENTIFIES NEXT INVASIVE SPECIES THREAT

NOAA Fisheries estimates there are only around 370 North Atlantic right whales left in existence – down from a peak of around 20,000 during the late 1800s.

Since 2017, the species has been experiencing an Unusual Mortality Event, which has caused dozens to become sick, injured or ultimately pass away.

“While entanglements remain the leading cause of death and injury, this year [2024] there were at least six vessel strike-related injuries/deaths, highlighting the importance of addressing this issue soon,” Heather Pettis, a research scientist at the Anderson Cabot Center and the chair of the North Atlantic Right Whale Consortium, previously stated. “The persistent aggregation of more than 50 right whales in the New York shipping lane this summer underscores this even further.”

Are you dreaming of a White Christmas?

You could be in luck if you live in certain spots of the Bay State.

A few rounds of snow showers in the days leading up to Dec. 25 means there’s a “decent chance” for a White Christmas in parts of Massachusetts, according to the National Weather Service’s Boston office.

The first round of snow is expected to come late Friday night into Saturday from an offshore coastal storm. Meteorologists are forecasting about 1 to 3 inches of snow, with the highest amounts across interior eastern Massachusetts.

“… Not expecting much in the way of impacts from this wintry system, more of a festive pre-Christmas snowfall that will drop anywhere from a coating to an inch or two from Friday into Saturday afternoon,” reads the National Weather Service’s forecast discussion.

Following the snow, get ready to bundle up. It will get downright frigid over the weekend.

“It will be one of the coldest air masses we’ve seen so far in the early portion of these winter months,” Andrew Loconto,a  meteorologist at the National Weather Service’s Boston office, told the Herald.

High temps on Saturday will be around freezing, and then the coldest air will be on Sunday when high temps will be in the low 20s — with wind chills around 10 to 15. The wind chills Sunday night could drop to five below zero.

Temps Monday should rebound into the upper 20s before ticking up for Christmas Eve and Christmas Day.

But as far as precipitation goes for Christmas Eve and Day, there could be rain or snow depending on where you live. It’s looking more likely for rain in southeastern Massachusetts, and snowfall across the interior.

A White Christmas is defined as one inch of snow depth measured on Christmas morning.

“The areas with the best shot for an inch of snow is probably interior New England,” Loconto said. “There’s a decent chance (for a White Christmas) for those interior areas, and for northeastern Massachusetts.”
