Good evening! What a treat it was weather-wise today! Temperatures topped off in the lower and middle 50s under mostly sunny skies. Get ready for a enormous change in the comfort level over the next 36-48 hours though.
Our storm is still expected to track close enough to us to give us a lot more rain than snow from it. However, the data has cooled slightly from yesterday’s numbers. The precipitation will begin as some scattered snow or mixed precipitation showers early Wednesday with little in the way of accumulation.
We should catch a break during much of the morning where it’s mostly dry except for a shower or two. In northern areas though, some occasional snow or mixed precipitation may continue. During the afternoon, rain will overspread all of western Massachusetts from northwest to southeast. The rain could become heavy at times by the afternoon commute and result in some poor drainage/urban street flooding. By this time, temperatures will have warmed well up into the 30s to near 40 south.
As we head into Wednesday evening and overnight, the fun begins! As the powerful storm center passes just to our south and then east, cold air gets rapidly pulled down in its wake and into western Massachusetts from the north. The result is the rain will first change to a period of freezing rain and then sleet and finally heavy, wet snow. This process may take much of the evening but takes place from north to south by midnight. After midnight, it’s all snow that falls. The snow will only be wet for a short while and then quickly becomes powdery as temperatures continue to crash. By dawn, readings will be all the way down into the teens in spots with blowing snow and strong winds. Any standing water or slush will be solid ice by then and road surfaces will become treacherous. The “flash freeze” will likely mean plenty of frozen car doors, locks and windows too!
During the day Thursday, the steady snow will quickly taper to flurries and end during the morning with clearing to follow in the afternoon. The sun will do little to warm us up though as highs stay in the teens north and in elevated areas to lower 20s south. Wind chills will be bitterly cold throughout the day and likely stay near zero. Winds will be strong enough to occasionally gust over 40 mph which means scattered power outages are possible.
The wind will diminish Thursday night and with fresh snow on the ground and an extremely cold late season air mass in place, record cold is possible once again. The record low for Friday morning is currently -2 set way back in 1948.
Snow Accumulations: Snowfall will range from just an inch or two along the Connecticut border to nearly a foot of snow possible in the higher terrain north of Route 2. Most of us in the valley will see between 2-6″ of snow from this storm.
