Winter on the first day of spring

Spring begins on Monday.  As it begins, we'll see some rain, snow and sleet in New England.

Today:  Bright sunshine, highs in the mid and upper 40s south, near 40 north.

Tonight:  Increasing clouds, lows in the mid and upper 20s south, teens north.

Tomorrow:  Snow to start, changing to rain in part of Southern New England(details below), highs in the mid and upper 30s south, upper 20s and low 30s north.

Tomorrow night:  Leftover rain and snow comes to an end, lows in the low 30s south, mid 20s north.

Tuesday:  Mainly cloudy, highs in the low 40s south, 30s north.

Discussion:
High pressure is still in control of the region for today, this will provide lots of sunshine and temperatures a few degress above normal.  A low pressure system will start to move in tonight, with the precipitation holding off until after the sun comes up tomorrow.  Most places, except maybe extreme southwestern New England will start with snow.  Gradually the rain/snow line will move toward the north and east, making it as far as Central New England, somewhere near Manchester, NH by late afternoon.  There will likely be a few spots that have a period of sleet in the morning to add to the fun.  Fortunately, there won't be too much accumulation on Monday.  Northern New England will have the best chance of accumulating snow with 1-2 inches possible, generally less than an inch everywhere else.

This low pressure system will move out of the region on Monday night.  Our sky will remain cloudy for the most part on Tuesday as we will only have a brief break before another storm system arrives on Wednesday.  This storm looks a little more potent and there again will be cold air around for some wintry precipitation.  Exactly what we will see remains to be seen, but right now I think it will be a bit colder than Monday's storm so I expect to see more in the way of accumulating snow.  More on this storm over the next couple of days.

Beyond Wednesday, it looks like our weather will be generally be dry, but below normal temperatures.  A large upper level trough will set up over New England, locking cold air over the Northeastern US.
