Snow Remains Possible Monday Night Through Tuesday Across Western & Central Mass

For Tonight: The area of low pressure which brought today’s snow (just measured about 2-1/2 inches of snow so far here in Sturbridge) will push to the east as high pressure builds into the region tonight. Any leftover light snow will end by 8 pm or so this evening with skies expected to remain cloudy throughout the rest of tonight. Temperatures tonight will remain between 15 and 20 Degrees. Winds will be Southwest at 5 to 10 mph. Sunday: A frontal boundary will push through the area during the afternoon. This means that the day will be generally cloudy, but quite a bit milder than today. In addition, some scattered snow and rain showers are possible during the afternoon. No snow accumulation is expected due to the above freezing temperatures. High temperatures will be between 40 and 45 Degrees. Winds will be Southwest at 10 to 20 mph with gusts to 30 mph. Monday: A high pressure system will briefly control our weather on Monday with partly sunny skies expected during the morning. An increase in clouds is then expected during the afternoon. High temperatures will be near 35 Degrees. Winds will be North at 5 to 10 mph. Snow Remains Possible From Monday Night Through Tuesday: An area of low pressure is expected to take shape near the Mid-Atlantic coast during Monday night and then track east-northeastward passing south of New England during Tuesday. There continues to be uncertainty as to the exact track of this storm system as latest weather forecast guidance have trended a little further south with the track of this storm as compared to yesterday at this time. These wobbles in the forecast storm track are perfectly normal for a storm that’s still 2 to 3 days away. The further south track of the low pressure system as shown by weather forecast guidance has to do with how amplified the upper level wind flow may be over Atlantic Canada. A more amplified wind flow would lead to this storm escaping quickly to the south, while more blocking in the atmosphere would cause the storm to slow down and come a little further north. The guidance that are showing the quicker exit of the storm to our south are now showing a general 3 to 6 inch snowfall with even some guidance showing as little as 1 to 3 inches of snow. Meanwhile, the guidance that are still showing a storm that slows down in forward speed are forecasting snow totals of 8 to 12 inches. Based on all of the available data, here are my thoughts: I do think that we’ll see snow overspread the entire area during Monday evening with the snow expected to continue throughout all of Monday night and probably all of Tuesday. Snow probably will come to an end by about sunset Tuesday afternoon. My latest thoughts in terms of possible total snow amounts are for something like 4 to 5 inches or so in the Connecticut River Valley, 5 to 6 inches for areas near and south of the Mass Pike, 6 to 7 inches for areas north of the Mass Pike and 7 to 8 inches or so for the Berkshires. That said, there is still uncertainty to whether that storm zips off to the east quickly leaving us with a minor snowfall or whether we see a storm that brings a more plowable amount of snow. Rest assured though, I will be sending more updates in the coming couple of days with the latest on this storm. Low temperatures Monday night will be near 25 Degrees. High temperatures Tuesday will be between 30 and 35 Degrees.
