Another round of snow is forecast for Tuesday and the latest computer trends are for more snowfall than originally forecast. Instead of a bitter cold blast after the storm this time around it will be milder temperatures that follow. We actually have a few days of above normal temperatures to look forward to through the second half of the week.
But first a word about Tuesday. Low pressure is going to develop south of New England very early Tuesday and quickly jump up the coast during the day to be positioned over southeast Massachusetts Tuesday evening. It will provide a heavy burst of snow early to late afternoon and probably impact the evening commute. The onset of snow is during the morning commute but is expected to remain on the light side through the morning hours. As the low races northeastward toward Nova Scotia the precipitation shuts off quickly early Tuesday night.
Snow accumulations have been increased to 3 to 6 inches across the Pioneer Valley. A Winter Weather Advisory has been issued by the National Weather Service.
Weather systems are moving at a fast clip this week and that means changeable weather conditions. Even though we dry out early on Wednesday another disturbance may bring a few light showers late day or at night before we briefly dry out again. Then, low pressure will push into southern Canada dragging a warm front through late Thursday or Thursday night followed by a cold front later Friday. A period of showers can be expected Thursday night with steadier and heavier rain likely on Friday.
Meanwhile, after Tuesday temperatures will become milder as the week goes on. Highs may be near 50 degrees Friday after climbing to around 40 Wednesday and the low 40s Thursday.
The seesaw probably continues into the weekend with a dry Saturday and possibly a wet Sunday.
