First Warning Forecast

Winter arrives tomorrow and snow is right on its heels

Posted: Updated:

Gusty northwest winds have been persistent this evening, but overnight they will gradually get lighter. Clouds decrease and temperatures drop with many reaching middle to upper teens by morning.

High pressure is in control Thursday, which will keep skies mostly sunny and winds light to calm. For the official start to winter, we will feel like it with high temps in the lower 30s. Temperatures return to the teens Thursday night under a mostly clear sky and it will be a dry, cold start Friday morning.

Friday Storm: A warm front approaches in the morning, bringing clouds back across western Mass. Light snow will eventually start reaching the ground by the late morning-early afternoon.

It’s looking like a minor snowfall for southern Mass with an inch or two along and south of the Mass Pike. Farther north, 1-3 inches are possible and north of Rt. 2 up to 6 inches may fall by Friday night.

We will start to see warm air nose in aloft, changing snow to freezing rain sometime in the evening in the lower valley, then farther north throughout the night. Light, scattered freezing rain continues into the overnight hours and possibly through Saturday morning for the valley and lingers in the hills into the early afternoon. Most should see a trace to a tenth of an inch of ice, but some higher elevations may get as much as 0.2". Power outages aren't a big concern here, but travel will be. Look for Winter Weather Advisories for snow and ice to be issued for this storm. 

Saturday is looking much colder compared to recent days and our temperatures linger in the 30s nearly all day, but we do get above freezing. We will see everyone change from an icy mix to rain-first the lower valley early in the morning, then eventually the hill towns and Berkshires by the early afternoon.

Scattered rain showers will be around through Saturday afternoon and night as a cold front passes through. We dry out Sunday morning and temps return to the upper 30s in the afternoon. It will be a quiet day-good for travel.

Christmas Eve/Day: Low pressure will develop Sunday and move up the stalled cold front from Saturday evening. This will push high clouds in during the afternoon and light snow around midnight. Now, the track of this low will determine if we see all snow or more of a mix, but for now, snow is looking likely at least at the start. If the low tracks closer to the coast or over SE New England, then we could go to a wintry mix (which may include ice) Monday morning for a time before changing back to snow on the backside of the low. It’s a tough call and we still have a few days to fine tune the details. It is looking like a tricky travel day though and something to consider for your Christmas Day plans.

This storm will be followed by a shot of very cold, dry air that sets in midweek. Some of the coldest temps of the season may arrives for Wednesday and Thursday!
