Weekend Forecast

An upper level disturbance will swing through New England today touching off an isolated shower or storm. The weekend will be top notch with mostly sunny skies and temperatures in the mid to upper 60's.  Sunday will likely be around 70.  After today's light rain there will be an extended dry period for 7-10 days.  Guidance is hinting at something around day 9-10 coming out of the SW Atlantic and being energized by an upper level system as it moves up the coast.  More on that tomorrow and next week.

Friday
Temperatures this morning are chilly especially outside of SE New England.
