Will Pats fans be tossing snow in celebration Sunday afternoon?

Local meteorologists are closely watching the chance for a coastal storm to bring some snow to the region as the Patriots face off against the Texans in Foxboro on Sunday.

Forecasters ahead of the weekend said the odds are increasing for at least “plowable snowfall” for portions of southern New England, especially for southeastern Massachusetts.

The track and timing are still uncertain, but the National Weather Service’s Boston office expects the snow will probably arrive Sunday afternoon. The Pats game kicks off at 3 p.m.

“We’re starting to see increasing confidence in the models that snow will be in the area,” NWS meteorologist Caitlyn Mensch told the Herald.

If the system tracks further west, then that would lead to higher amounts of snow across the region.

But if the coastal system tracks further offshore, that would lead to lower amounts.

Overall, it won’t be a major whopper of a storm — like the 2002 blizzard Snow Bowl when the Pats beat the Raiders following the Tuck Rule and kicker Adam Vinatieri’s heroics.

“The greatest probabilities for seeing 2″+ of snow are generally southeast of the Boston to Providence corridor, followed lower probabilities for rest of RI, northeast CT, pushing back toward Worcester and lower as you go further west,” the National Weather Service wrote.

“It is still worth considering the potential for a further west extent of plowable totals at this time,” NWS added. “Across all guidance, the probabilities for 6″+ are low to none which at least leans totals more likely toward the Advisory level in the favored areas.”

There’s a general consensus for snow to begin sometime in the afternoon Sunday before pushing out very early Monday morning.

Forecast details should continue to become more clear as the system approaches, which will help nudge amounts and potential Winter Advisories/headlines.

Ahead of Sunday, forecasters were tracking snow for Saturday across western Massachusetts and northern areas of the state.

A Winter Weather Advisory is in effect on Saturday for portions of the region. Meteorologists expect widespread accumulations of 2 to 4 inches, with locally higher amounts of up to 6 inches across the Berkshires.

Temps will remain warm enough for only rain in eastern Massachusetts on Saturday.

“The snow will impact travel conditions especially from the Berkshires to Worcester Hills,” NWS wrote. “Lesser impacts expected in low elevations where temps a bit above freezing will limit accums on roads.”

Then after the second chance for snow on Sunday, it’s going to get downright frigid.

There will be a shot of arctic air Monday night as a cold front pushes through. That will bring well below temps and bitterly cold wind chills, with the coldest temps felt Tuesday.

“This will translate to the surface with high temperatures Tuesday ranging between 15 to 25 degrees,” NWS wrote. “To put it into perspective, that’s about 10 to 15 degrees below normal temperatures for that time of year. To add on, winds will be favored to be breezy to gusty Monday night and Tuesday.”

Wind gusts could be up to 35 mph Monday night through Tuesday.

This will plummet wind chill values into the negative single digits to single digits Tuesday morning, and single digits in most spots during the day Tuesday.
