The northeast is prepping for snow on Saturday, with bitter arctic cold to follow by Sunday morning. 

The National Weather Service issued a winter weather advisory for the areas of Boston, Worcester, Providence and Manchester, New Hampshire, with a winter storm watch issued for Essex County. And a cold weather advisory is in place for Sunday — the city of Boston issued a cold emergency.

Friday is a transitional day, as we get light snow to flurries due to ocean effect offshore and along the coast through the day. Temps will be in the 20s to near 30, with cloudy skies for everyone in New England. Tonight’s lows drop to the teens and 20s, with incoming snow out in western New England.

Saturday snow

The First Alert Weather Team has issued a First Alert for Saturday’s snow. The updated snow map (issued Friday at 11am) shows an increase in totals at the coastline. This is due to a Norlun trough and ocean effect that typically enhances lift and therefore, snowfall. 

Scattered snow showers will start up in western New England Friday night, moving into Boston by sunrise Saturday. The heaviest snowfall rates seem to develop around midday Saturday and from the New Hampshire coast, then spinning down into the south shore by mid afternoon through Saturday evening. 

The scattered snow showers taper inland, while the mountains see several inches of snow due to upslope development Saturday evening. Lingering outer Cape Cod snow showers will be around for Saturday night with a gusty northwest breeze. Stay tuned to snow map adjustments as the system develops. 

Dangerous cold Sunday

Another First Alert is on for Sunday as we see the coldest temperatures and wind chills of this season.  Extreme Cold Warnings and Advisories are up for Saturday night through Sunday midday.  Wind chills will be -20 to -30 degrees as actual lows drop to around zero. The wind remains strong 30-40 mph gusts from the northwest Sunday morning, slowly subsiding to 20 mph gusts at night. 

The cold means it is a great day to stay inside and watch all the Patriots Super Bowl coverage on NBC10 Boston. The big game will be warm and in the 60s by kickoff out in California. 

10-day outlook

The cold remains for Monday as highs will be in the teens to 20s with some sun. Slowly, we see milder air returning midweek as highs reach the mid 30s. 

A wintry mix to snow showers will be around as a system moves in for Wednesday into the end of the week. There’s a possibility that the storms stalls offshore in the Gulf of Maine for the end of the week and if that happens, we will trend colder with snow near the shoreline. Another model shows a similar trend with the system stalling nearby, but with less precipitation from it. 

Stay tuned to updates on the forecast as we near Valentine’s Day next weekend.

Boston Police, working with the US Postal Service, seized six kilos of drugs worth over $1 million in an East Boston bust Tuesday.

Officers executed search warrants at multiple locations, including 11 Trustman Terrace and 906A Saratoga Street.

During the operation, police said they recovered 3.5 kilos of fentanyl and 2.5 kilograms of cocaine, valued at about $1 million and $150,000 respectively. They also found a 9mm large-capacity semi-automatic firearm, a large-capacity feeding device, ammunition, an additional feeding device, as well as cellphone, an undisclosed amount of U.S. currency and pills they believe to be narcotics.

Police arrested Anny Perdomo-Santana, 35, of East Boston, for allegedly trafficking the drugs they seized.

Perdomo-Santana faces charges of trafficking more than 200 grams of fentanyl, trafficking more than 200 grams of cocaine, unlawful possession of a large capacity firearm, unlawful possession of a large capacity feeding device, firearm violation in commission of a felony, and improper storage of a large capacity firearm near a minor.

“Additionally, an individual was summonsed to court, in lieu of arrest, to face a charge of Trafficking of a Class B Substance (Cocaine) Over 200 Grams due to medical considerations identified at the time of the enforcement action,” BPD said in a statement.

Citing “chaos” on the streets of cities like Minneapolis and Lewiston, Maine, and referencing the fatal shootings of Renee Good and Alex Pretti, Mayor Michelle Wu announced a series of executive actions designed to hold federal officials accountable in Boston.

Wu said in an executive order Thursday that city departments shall “work with the Boston Police Department to publicly release video footage of violence or property damage by federal officials captured by Boston Police Department body-worn cameras or other City-controlled surveillance cameras.”

The hope, the mayor’s executive order says, is to deescalate any potential confrontations.

Wu’s order comes as speculation continues to swirl around the city that a surge of federal immigration officers is imminent. Last month, the Herald photographed the delivery of scores of new SUVs to an ICE operations center in Burlington.

Wu cited violent clashes between protesters and ICE officers in Minneapolis, noting the fatal shootings of Renee Good and Alex Pretti, in her order.

“In these deployments, federal agents have fomented chaos, violated residents’ constitutional rights, and perpetrated egregious acts of violence, including the fatal shootings of Renee Nicole Good and Alex Pretti,” Wu’s order states.

The mayor is also seeking to restrict federal officials from using city property without a court order or warrant, declaring that Boston property, parks or even parking lots cannot “be used as an unpermitted staging area, processing location, operations base, or any similar purpose in furtherance of civil immigration enforcement operations.”

The mayor’s order was issued during a press conference Thursday at City Hall.
