Light Snow Showers Monday AM

A cloudy Sunday AM start will give way to party cloudy skies this afternoon with max temperatures right around 40.  Winds will diminish as the day progresses and we stay dry.  A fast moving atmospheric wave will arrive in the pre dawn hours Monday bringing a brief burst of accumulating snow to Southern New England.  A lot of factors will prevent this from being a big event but it will impact the AM commute in Hartford, Springfield and Worcester metro areas.

General Overview
If you have stepped outside for church, grocery shopping, sports etc you will notice the air has a cold bite to it.  AM lows were in the mid 20's for much of SNE.

We will rebound and clear up a bit but temperatures will still a few degrees below average for early December.  The Patriots will be dry today as they take on the Rams and for December that has to be considered a win if you have tickets to the game.  High pressure slides east throughout the day as our next weather makes quickly tracks east behind it.
WPC Surface Fronts/Precipitation Sunday 7 PM
The precipitation will enter SW New England between 3-4 AM and will work into the Springfield and Hartford metro areas before 5 AM and between 5-6 AM in the Worcester area, 6-7 AM in Eastern MA.  Ignore the green fuzz in this image it will be cold enough to support snow tomorrow AM this is just too light to reach the ground.

The heaviest burst of snow is from the get go before the snow intensity wanes throughout the AM.    By noon the precipitation will be switching over to light rain south of the MA Pike and also ending from west to east.

Temperatures tomorrow AM will be in the upper 20's.  Temps climb into the mid 30's for highs tomorrow PM (near 40 at the South Coast).

SO how much snow will fall?  Very little.  1-2" tops in Central MA/RI/E MA.  I can see a few 2-3" spots in Western MA/CT and in the higher elevations of NW Worcester County.  I would advise DPW crews to pre-treat roads overnight.
NWS Boston snowfall accumulation forecast Monday 
There will be more chances for precipitation during the week and another cold blast Thursday PM into Friday AM.  I'll update as needed this evening.
