Breezy and Mild Monday. Showers / Few Downpours / Likely Tonight

Simulated Radar Imagery for Today and Tonight

A warm southwesterly flow of air developed on Sunday and pushed temperatures back into the 60s for afternoon highs. Readings continued to tick upward last night and we started our work week with temperatures between 65 and 70F around the Cape. With some partial sunshine around the area and a continued flow of mild air into the region on southerly winds, we’ll see readings top out in the 70s across most of the Cape today. There will even be a touch of humidity in the air as dew point values climb through the 60s.

The warm and “muggy” air won’t stick around for too long as a much cooler air is poised to return to the region on Tuesday and remain in place through the remainder of the upcoming week.

That cooler air mass will arrive tonight courtesy of a cold front approaching our area from the west. That frontal zone will sweep eastward through our region overnight, bringing with it numerous showers and likely a few embedded downpours. In fact, some of our high resolution short-term convective model guidance show multiple rounds of heavier showers developing and crossing the Cape tonight, yielding some notably heavier rainfall totals vs our lower resolution global models – totals closer to 1 inch vs 1/3 of an inch.
