The snow hitting the Boston area Saturday has temporarily impacted travel at Logan International Airport.

A ground stop was issued in the afternoon for snow and ice at the airport, at least briefly grounding flights headed to Boston while departing planes were being deiced, according to the Federal Aviation Administration.

Flight delays were expected along with the ground stop, which was set to be reevaluated at 2 p.m.

The city was expected to get 3-6 inches of snow by the end of the day, though parts of the North Shore had already gotten about a foot of snowfall before noon on Saturday.

Snow began falling in Boston early Saturday, and it could drop half a foot in places around the area, with a winter storm warning is in place north of the city. Here’s the latest forecast — plus a look at the frigid temps on Super Bowl Sunday.

CHESTNUT HILL – The Boston College men’s hockey team got ensnared in a Beanpot trap.

On the eve of a historic encounter, No. 11 Boston College was ambushed 6-1 by the Vermont Catamounts in a quantifiable trap game upset on Friday night at Conte Forum.

The Eagles fell to 15-9-1 overall and 10-6-0 Hockey East in their dress rehearsal for the 300^th Battle of Commonwealth Ave. against crosstown nemesis Boston University, a rivalry that dates back 108 years.

“Probably,” said BC coach Greg Brown when asked if he thought his players were looking ahead to Monday. “We talked about this game a lot, for league standings, for national standings, everything is important and we weren’t sharp enough.

“We have to get over this in a hurry. We will take a look at it, regroup so we can be sharper. We know we can’t make those kinds of mistakes and win games.”

The timing of the milestone match could not have been scripted any better. BC and BU will play for the 300^th time in the championship game of the 73^rd annual Dunkin Beanpot Tournament on Monday night (7:30) at the TD Garden.

The defending champion Terriers will engage the Eagles for the 24^th time in the title match. BU is going for its record 33^rd Beanpot title while BC looks to secure its 21^st. BU leads the overall series, 141-137-21.

BC advanced to the Beanpot title game with a 5-1 victory over Harvard. Boston Bruins 2025 first round draft pick and Hobey Baker Award nominee James Hagens had two goals and an assist against the Crimson.

BU scored two shootout goals after three-on-three overtime to beat Northeastern in the other semifinal. The game went into the books as a 2-2 tie with BU winning in the shootout. The No. 9. Terriers beat the No. 1 Eagles 4-1 in last year’s championship game.

“The timing just adds more excitement to it for everybody,” said Brown. “We know they are a great team and we have to play better than we did tonight.

“We have to play faster and execute at a higher level. It is going to be a fun game. I think both teams are capable of playing a lot of good hockey. It will be exciting to see who can execute better.”

BC showed early signs of being embroiled in a trap game when Vermont scored two unanswered goals in the first period. Top line center Colin Kessler forced a neutral zone turnover, broke in on the left flank and backhanded the puck around BC goalie Louka Cloutier at 1:20 for his fourth of the season. Vermont made it 2-0 when sophomore left wing Ethan Burroughs beat Cloutier top shelf on the glove side for his third of the season at 8:24.

“I thought it was a complete game from head to toe from our guys,” said Vermont coach Stephen Weidler. “I certainly felt like from the net all out we were dialed all the way into what our identity is and what our system needs to be.

“We were just playing our version of hockey. BC had their pushes and we didn’t get bored with being simple. We knew we had our hands full but for us it was about our process and staying focused on the first task at hand.”

BC attempted to dispel the notion of a trap game on the power play 47 seconds into the second period. The Eagles cut the lead to 2-1 when Hagens redirected a Lukas Gustafsson slapper from the point for his 15^th of the season.

Vermont appeared to take a 3-1 at 7:20 but the replay revealed that defenseman Caeden Herrington kicked the puck into the net. Undaunted, Vermont went up 3-1 on the power play at 12:40 when Herrington set up junior defenseman Sebastien Tornqvist for his fourth of the season.

Vermont went up 4-1 at 2:27 of the third on a scenario that added injury to insult. On the same play that senior left-wing Massimo Lombardi netted his fifth of the season, BC freshman center and Bruins’ draft pick Will Moore left the game in pain with an apparent right shoulder injury. Vermont freshman right wing Matteo Michels scored on a breakaway to make it 5-1 at 5:39.

“There is no update on (Moore) at all,” said Brown. “It looked like he got caught in an extended position but hopefully he is okay.”

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.
