Cold Start Tuesday, Warmer & Wet Tonight

It is another frigid morning in the cold valleys of interior SNE. Low pressure will track to our west today dislodging some of the cold air.  There will be some wintry precipitation is Western MA this afternoon.  Overall precipitation will have to overcome dry air in Southern New England so by the time it falls it will be as rain.   It is certainly colder this morning than originally anticipated.

Temperatures will stay cold through 9-10 AM.  It is coldest where the wind is calm.  The regional radar shows a band of showers associated with the warm air push in Western PA/NY.
NWS Northeast Regional Radar 
That is snow right now as the precipitation is well ahead of the actual storm system.  As the whole mess pushes east this changes to sleet/ice before going over to plain rain.

Max temperatures for Wednesday will be in the AM.  Temps drop into upper 30's for PM but return near 50 on Thursday.  The thaw is on and might be around for a couple weeks.  That said it only takes a few hours for some snow to screw things up so we will be watching.  All records appear safe for the date.
