High pressure currently positioned off the Northeast coast will continue to influence the Delmarva region through today, delivering dry conditions and a gradual warming trend. As this system shifts offshore tonight, a return flow will develop, allowing temperatures to climb closer to seasonal averages today and well above normal by Thursday.

Expect increasing cloud cover through the day, but temperatures will still respond nicely. Highs this afternoon will reach the mid to upper 50s across Delmarva, followed by a much warmer day on Thursday with highs surging into the upper 60s to near 70 degrees.

This brief stretch of mild weather will be interrupted by an approaching cold front tied to a low pressure system tracking through the Great Lakes into eastern Canada. Rain showers will begin to move into the region Thursday evening, initially across western areas, before spreading southeastward overnight into Friday morning. Rainfall totals are expected to range between a quarter to a half inch.

There is also a slight chance for a rumble of thunder as modest elevated instability develops along the front, though severe weather is not expected at this time.

Winds will become a factor as well. A breezy southwest wind develops Thursday ahead of the front, with gusts increasing to 25 to 35 mph. Behind the front, winds shift to the northwest on Friday, maintaining gusty conditions and ushering in a much cooler air mass.

Temperatures will actually fall through the day on Friday due to strong cold air advection, setting the stage for a chilly start to the weekend. Highs on Saturday will struggle to reach the 50s across Delmarva.

Looking ahead, conditions improve by Sunday as high pressure builds back into the region. Skies will remain dry, and temperatures will moderate closer to seasonal norms.
