New England faces frost risks as tropical activity develops in the Gulf

Southern New England is expected to experience a quiet weather week characterized by a cold air intrusion. Temperatures are projected to drop into the 30s in some interior locations on Monday and Tuesday nights. A risk of frost is anticipated across sizable portions of interior southern New England due to clear skies and light winds promoting radiational cooling.

In Maine, the National Weather Service has issued frost advisories for coastal regions and freeze warnings for interior Cumberland and Androscoggin counties. Temperatures in some inland areas, such as Fryeburg and Rangeley, could fall as low as 25 degrees. While these sub-freezing temperatures are expected Tuesday night into Wednesday, warmer air from the southwest is projected to bring more seasonable conditions later in the week, with some areas reaching 70 degrees.

In the southwest Gulf, an area of showers and thunderstorms is expected to organize into a tropical depression by mid to late week. This system may increase the threat of heavy rain for portions of the U.S. Gulf coast toward the end of the week or the upcoming weekend.
