Rain today, Quiet Pattern Follows

The highest temperatures of the day are being recorded right now.  A strong cold front is pushing east across New York and into New England.  There is a strong temperature gradient
From NCEP temperatures at 4 AM.  Widespread lower 60's (deep blue)
Along this gradient there are heavy showers and embedded thunderstorms

First band will likely reach Central MA before 7 am while the bulk o the rain will fall between 9 AM and 3 PM.  Short range computer guidance has hinted at some moderate thunderstorms around 7-8 AM.  Temperatures will drop like a rock after the cold front passes.  Expect temperatures to fall from the mid 60's to the upper 40's.   After today the weather settles down for a 4-5 day stretch.  Temperatures will be in the mid to upper 40s Wednesday through Sunday.  Skies will be mostly sunny until Sunday, when clouds will begin to build back in.

There is a lot of chatter about a potential Nor'Easter next week.  It looks likely that something will form and try to move up the coast.  The American GFS from Dr Ryan Maue's Weatherbell model page
00z/13 run, hour 156.  
And the EURO
00z/13 run, hour 192
There are significant differences in both model runs.  However at this range it is important to note that each of the models is picking up on a coastal storm.  Each model also has high pressure to our North and East.  This needs to be watched because if the high ends up further over New England we could see snow from this event.  Thanksgiving week is always very busy so this storm may cause a lot of headaches and travel delays.  Will keep you posted.
