Today starts a much cooler stretch across Delmarva with mostly cloudy skies, highs in the mid 50s, and gusty winds. The biggest concern is tonight, when a widespread freeze is expected inland with a Freeze Warning in effect from midnight to 9 AM Tuesday. After a chilly Tuesday, temperatures rebound into the 60s and 70s by mid to late week before cooler weather and a better chance of rain return for the weekend.
