Today stays below average across Delmarva with partly sunny skies, highs in the upper 30s to low 40s, and a cold east-northeast wind off the ocean keeping conditions raw. Tonight turns partly cloudy with lows in the upper 20s to low 30s. The chill lingers Thursday before a warmer trend arrives Friday, the first day of spring, with highs near 60. Even warmer air builds in for the weekend, pushing temperatures into the 60s Saturday and low 70s inland Sunday before showers and cooler air return early next week.
