Good-bye Isaac…

Training thunderstorms produced major street flooding for a time in SE Mass earlier today with many towns receiving between two and three inches of rain in about 2 hours.  This was simply too much for storm drains to handle and water backed up on the streets.  The worst hit area was Fall River where over five inches of rain fell…much of the city was undrivable this afternoon.  Today’s drenchers were remnants of Isaac and thankfully they are now shifting offshore with drier air filtering in for the next 24 hours.

Dew points are in the process of dropping back to more respectable levels from the lofty 70s to the more comfortable 60s, this will set the stage for a solid Thursday with a mix of sun and clouds and temps a little above normal in the lower 80s inland and seabreeze cooled 70s at the coast.  Another front will approach on Friday and out ahead of it southerly winds will grab the muggy air sending it our way for several days.  The inbound front on Friday will be able to tap into that increasing moisture providing a storm chance.  The highest chance appears to be late morning and early in the afternoon with the threat diminishing later in the day as warm air advection aloft should start to cap any convection.

The weekend is going to be very very soupy.  A pattern changing trough will dig out of the Lakes to the East Coast over the weekend.  Along the leading edge a very active, slow-moving coldfront will be producing more torrential downpours.  WHile the air will be very sticky on Saturday, the forcing along the front will still be off to the west so much if not all of Saturday will be dry.  Sunday, however, will be a different story with soaking downpours and thunderstorms for the morning that may linger into the afternoon.

We will be rewarded with some lovely weather early next week.
