Less Humid Air on The Move...Cooler MidweekA warm and muggy night, but a cold front will push off the coast and drier air will move in overnight with clearing skies and lows in the 60's. Tuesday will be a warm, but less humid day. There will be plenty of sun in the morning, but cooler air aloft supplied by an upper level low over us will keep the air unstable. Expecting building PM clouds with the potential for a spot shower or thunderstorm. Breezy WNW will warm the coastal plain with many areas climbing into the mid-upper 80's
Tracking A Few Showers Before An Improving Weekend.The cold front which helped to trigger strong to severe storms late yesterday across the Pioneer Valley has weakened and stalled over southeast MA. This cold front will likely become the trigger for a few scattered showers or thunderstorms to form later this afternoon across Bristol, Plymouth and Barnstable counties. These areas, including along the south coast have dewpoints in the upper 60's to near 70 which will help to fuel the scattered afternoon convection.
Rainy Mix This Time..But A Wintry Week AheadA solid .50"-1" of rain is likely and this water will easily be absorbed by the snow pack to only become heavier and add more stress to the rooftops. As the storm deepens over us tonight and pulls away, a change over to snow will occur mainly after midnight..with northern New England having the best chance of any substantial snowfall. SNH could see 1-2" with N. MA a coating to an 1" at best as the storm departs.
