Truly Miserable Tuesday

Between 1 and 2 AM, Worcester Airport reached 50 F for the day.  If we can't get over 51 this afternoon Worcester will break a record for lowest maximum temperature for the date.  Our 3 other major climate sites will come close but ultimately will land a degree or two over the record low max.
The first batch of rain was delivered by a storm tracking south and east of Nantucket.  If we had the temperature anomalies we are seeing today in late January with this storm track we would be in business with a big time winter storm (or at least I would, snowstorms are big $$, thanks!).  Alas, it's June 6 so I apologize for even bringing up snow.
WPC Surface Fronts/Precipitation Tuesday 8 AM
Although the low is moving out to sea, rain will return later this AM as the upper-level disturbance that has been squatting to our west for days will finally make its way into the Atlantic.   Here is the regional northeast radar as of 6 AM.
NWS Northeast Regional Radar Loop through 548 AM
Showers are ending across most of Southern New England.  Light showers and drizzle will remain for the AM commute.  You can spot the low-pressure center in Upstate New York on the radar. That will work west throughout the morning. Steady rain showers will return from west to east after 10 AM in Springfield, 12 PM in Worcester, and 1 PM in Boston.

The heaviest rain today will be in the Berkshires where up to 1" is possible.  Over a 0.5" is likely north of a line from New Haven to Providence to Plymouth up into S NH and VT.

Winds out of the east will gust up to 40-45 MPH along the east coast of Massachusetts.  Sustained winds will be 20-25.  Elsewhere winds will gust up to 30 MPH with sustained winds 10-15 MPH.

It really is days like this that give New England a terrible weather reputation.  East Northeast winds off the cold ocean with an air mass that will only allow temperatures to rise into the upper 40's and low 50's.

High pressure will build to our west so showers will begin to wane tonight.  A few leftover showers will be possible tomorrow morning.  The high marks the beginning of a transition phase for our weather.  Another coastal storm is likely Friday before the summerlike weather makes a return next week.
