This Afternoon Through Tonight: An area of high pressure will continue to control our weather this afternoon through tonight. Lots of sunshine is expected for this afternoon and it will continue to be cold. Temperatures this afternoon will be around 20 Degrees. Clear skies and bitter cold temperatures are expected tonight with low temperatures near Zero. Sunday: High pressure continues to control our weather for Sunday. Lots of sunshine is expected in the morning, however, there will be an increase in clouds during the afternoon. High temperatures Sunday will be near 25 Degrees. Long-Duration Winter Storm Expected From Monday Afternoon To Tuesday Night: An area of low pressure is expected to form near the Virginia coast on Monday morning and head slowly northeastward reaching near Nantucket late Monday night and Tuesday morning. This storm is expected to hang near the New England coast into Tuesday night and Wednesday. This means that a long-duration snowfall is expected across Western and Central Mass beginning on Monday afternoon and continuing until Tuesday night. It should be noted though that the heaviest snowfall is expected to occur from late Monday afternoon to Tuesday morning when most of the snowfall will accumulate. Much lighter snow is then expected during Tuesday afternoon and Tuesday night before it ends Wednesday morning. Here Is My Thinking As Of Right Now: Snow will begin across Western and Central Mass by early Monday afternoon. A period of moderate to heavy snow is then expected from late Monday afternoon through Monday night into Tuesday morning, especially across Central Mass. Light snow is then expected during Tuesday afternoon and Tuesday night with the snow finally coming to an end during Wednesday morning. Our forecast snow total map is attached to this post.
At the time of this writing (12:30 pm), snow has begun across southwestern Connecticut and the leading edge of this snowfall is progressing to the northeast. It is expected that snow will begin across Western Mass by 2 to 3 pm. The snow will then begin across Central Mass by 3 to 4 pm this afternoon. Once the snow begins, it should come down at a fairly quick rate on the order of around one-half of an inch per hour from late this afternoon through this evening before it lightens up in intensity by about midnight tonight. Intermittent light snow is then expected to continue into at least part of the day Wednesday before it finally comes to an end by Wednesday night. Total Snow Accumulations: It still appears that 3 to 4 inches of snow accumulation can be expected. Most of that snow is expected to accumulate between late afternoon today and midnight tonight. Road conditions are likely to be slippery during the last half of this afternoon through a majority of tonight. So, use care when traveling later this afternoon and tonight. The Next Chance For Snow looks to be on Sunday night and Monday as an area of low pressure takes shape to the south of Long Island and heads for the Cape and then towards Nova Scotia. The track of this storm will be crucial in determining how much snow accumulates across the region. Some of the weather forecast guidance are showing a moderate snowfall on the order of 3 to 6 inches. Other weather forecast guidance are showing quite the large snowstorm with a foot or more possible, especially across Central Mass. At this point, I’m leaning more towards the moderate type snowfall accumulations, but I’m not at all ruling out a much heavier snowfall. So, as I already mentioned snow looks quite likely across Western and Central Mass throughout Sunday night and Monday with the snow ending late Monday afternoon or Monday evening. Overall, my thinking is for a 3 to 6 inch snowfall across the region with perhaps up to 8 inches possible across Central Mass. Again, this is a early call and the forecast of this snowfall is very likely to undergo changes in the coming days, so stay tuned.
