Light Snow Tonight

A weak cold front will slide across New England tonight.  A weak ocean storm will pass well to our South at the same time.  These two features will produce some light snow tonight across Southern New England.  It appears the snow will set up north of the Pike and outside I-84 but some flurries are possible from 95 to 495 and some rain iis possible in SE MA/RI.  Little to no accumulation is expected.

Short Term Forecast
Here is the forecast surface fronts and precipitation for 8 PM tonight.
WPC Surface Fronts/Precipitation Tuesday 7 PM
The latest simulated radar returns for this evening show a decent band of snow moving through Southern New England around 10 PM.   By midnight it snow stretches from Lowell to Springfield.

By 6 AM most of the precipitation is off the coast with the exception of the Cape/Islands.

There will not be much wind as this front passes.  There also will not be much of an air mass change for tomorrow.  Low temps tonight are in the upper 20's tonight in the interior and low 30's in the coastal plain of SE MA.

High temps Wednesday rebound into the upper 30's but look to the west to see the highs that are coming for Thursday and Friday.
NWS maximum temperatures Wednesday (image Weatherbell)
We will have a few more shots at snow this week but nothing major.  The big story will be the cold Thursday-Saturday AM. Some snow is likely Saturday AM before going over to rain.  How can it go from near 0 to rain in 36 hours?  I'll show you tomorrow.
