Mainly Rain for SNE

Snow will fall tomorrow night into the morning before changing over to plain rain.  A surge of warm marine air will work into New England overwhelming the cold at mid levels.  The Berkshires, extreme Northern Worcester County, and NH, VT, and ME will do well with this storm.

Timing
Snow breaks out West of 495 in MA and North of 95 in RI/CT between 1-4 AM.  It will accumulate in these areas until 7-8 AM before daylight and warm air take over South of the MA Pike.  Here is the latest NAM with snow totals by 10 AM Wed
06z NAM 33 hour snow totals (image weatherbell)
I expect Northern Worcester County to do better than this model is advertising but the rest looks good.    The NAM and EURO agree in principle.  Here is the storm total by Thursday Morning
06 NAM 60 hr forecast
Total precipitation 
HPC 3 day precip totals
Finally there is some hint that another low pressure system tries to form Thursday Afternoon/night.  It may be like Sunday afternoon or something heavier in SNE.  I'm still watching that.  Average confidence in the forecast overall.  

Enjoy today, highs in upper 30's/low 40's with a mix of sun and clouds.
