Scattered Showers This Afternoon

Cold air in the upper atmosphere will help to keep temperatures in the 50's with scattered showers this afternoon.  This cold air is left over from the rainstorm over the weekend.  While the cold pool will slowly dissipate and move east, it will linger for the rest of the week.  The weather will be dry most of the time, but a few isolated showers will be possible.

General Overview/Current Conditions
Temperatures have fallen into the mid 30's across most of Southern New England.  Clear skies and light winds have led to the development of frost in SE MA.

Temperatures tonight will again fall into the mid 30's.  Frost will again develop in the typically prone regions.  Temperatures are forecast to be near 60 tomorrow.  There is a slight chance of showers, mainly in Eastern Massachusetts.   Below normal temperatures will linger into the weekend.  There is a chance for another coastal storm Saturday night into Sunday.
