Rain with Isolated Thunder This AM

Some of you may have awoken to a few rumbles of thunder this AM (I know I did).  Bands of showers and thunderstorms are wrapping around a surface low south of New England.  The first band is lifting through the Blackstone Valley now (as of 445 AM).  This band extends to Boston and Springfield as well.  I expect another band around 8 AM.  Here is the radar loop this morning

The counter clockwise motion of the low shows up nicely on radar.  Here is the zoomed in surface chart

Here is the radar as of 8 AM.  I feel this could be overdone in Eastern MA but keep the umbrella handy and give yourself an extra 15 minutes if you are commuting this morning.

The rain shifts to Western MA and Northern CT this afternoon.  We should stay dry in Central and Eastern MA/RI.  Northeast winds keep temperatures around 60-65.  Winds begin to shift this afternoon and temperatures will rise overnight.

I have some changes to my weekend forecast that I will discuss in my next post.
