For The Rest Of This Morning: Partly to mostly sunny skies are expected throughout the rest of this morning. This sunshine will be short-lived as an Arctic cold front approaches the region from the northwest. By midday, temperatures across Western and Central Mass will be in the low to mid 30s.
Snow Showers & Snow Squalls This Afternoon Into This Evening: An Arctic cold front is expected to push across the region later this afternoon and this evening. The combination of daytime heating, low level moisture and forcing from the Arctic cold front will lead to scattered snow shower activity to impact Western and Central Mass beginning around mid-afternoon today.
In addition, the atmospheric parameters for snow squall development are expected to be favorable from about 3 pm this afternoon to about 7 pm this evening.
So, I think that we will see scattered snow shower activity break out across Western and Central Mass by about 2-3 pm this afternoon and continue into early this evening. The highest chance for snow squall activity is expected across the Berkshires and the Pioneer Valley/I-91 corridor between about 3 pm and 6 pm today and then across the Worcester Hills between about 4 pm and 7 pm today. Any snow squalls will have the potential to drop a very quick 1 to possibly 2 inches of snow accumulation in under 30 minutes with gusty winds, leading to dangerous near-zero visibility conditions on area roads. This could make for difficult travel in a few spots during this afternoon and evening’s commute.
Tonight: Arctic air will pour into the region on gusty west to northwest winds which will gust up to 35 mph at times throughout tonight. The gusty winds combined with plummeting temperatures will lead to wind chill temperatures of 10 to 15 below zero. Low temperatures tonight will be between 5 and 10 above zero.
Thursday: An area of high pressure will gradually build into the region on Thursday. Even though it will be sunny to partly sunny on Thursday, it will be cold with high temperatures between 20 and 25 Degrees. Northwest winds will gust up to 30 mph at times which will lead to wind chill temperatures of around 10 below zero during the morning and near 5 above zero during the afternoon.
Quiet Weather is then expected from Friday right through at least Christmas Day.
