Rain Tonight, Close Call Thursday

So here we go again!  Low pressure off the Carolina coast is tracking Northeast towards New England.  At least two more areas of low pressure will follow this Thursday and Friday,  Here is the surface chart

The rain tonight will be heavy at times especially in Southeastern MA.  Here is the northeast regional radar loop.  There is a noticeable expansion of moisture in CT.

The rain sticks around until 11 PM in CT, midnight Southeastern MA.  In Central and Northeastern MA some showers will stick around through 5 AM.  With the rain is the cold temperatures.  Outside of CT and RI most of Massachusetts is in the 40s.

Temperatures tonight drop down to the low 40s.  There will not be much of a rebound on Thursday.  A mini spring nor'easter will develop from the low I circled in the Great Lakes in the image above.  Here is the water vapor satellite that shows the general flow through the Eastern US

Showers return mid morning tomorrow.  The biggest threat for heavy rain tomorrow is Eastern MA closer to the coast.  Winds will also gust up to 30 MPH near the coast so it will feel like its about 40 tomorrow in Plymouth, Boston, Gloucester etc.  Showers and some steady rain will extend back into RI and Worcester County tomorrow afternoon as well.  The good news with this system is some guidance is taking it just far enough offshore that its just some rain and drizzle.  But either way tomorrow is another miserable May day.

I am finally seeing some signs of warmth but its not for another week or so.  For now I'll settle for a glimpse of the sun on Saturday afternoon and maybe 60-65 Sunday?  Fingers crossed.
