Arctic high pressure keeps Delmarva cold through Tuesday, with clouds increasing and a brief window for light snow late today into this evening. Any accumulation should be minor and mainly on grassy or elevated surfaces, with roads staying mostly wet as snow melts. Overnight, snow changes to sleet or a wintry mix, then turns to light rain by Tuesday morning. After a damp Tuesday, temperatures surge mid-week into the weekend, running 10 to 20 degrees above normal with occasional showers and even a chance for a rumble of thunder Thursday night.
