The Monday morning radar analysis showed a growing area of showers and embedded thunderstorms over the Mid-Atlantic states headed northeastward. This initial batch of wet weather is expected to spill into western portions of Southern New England over the course of the afternoon hours, reaching our neck of the woods as scattered showers this evening.
Consequently, our morning sunshine is expected to fade out behind advancing clouds through midday and early afternoon, with skies trending toward overcast this afternoon. Temperatures in the 50s and lower 60s first thing this morning will rise into the middle 70s for highs.
A second surge of moisture is forecast to approach the region tonight as a wave of low pressure develops and passes very near or over Cape Cod and the Islands during the overnight hours. It is this follow-up wave of moisture that has the potential to produce some pockets of very heavy rain and possibly a few thunderstorms. Activity should shift eastward and offshore toward dawn Tuesday with slow drying thereafter.
