DELMARVA - The beach communities are in for a sharp weather shift from early Wednesday morning into early Thursday, with summerlike warmth giving way to showers, thunderstorms and cooler air overnight. Forecast guidance for Delmarva shows the cold front reaching the peninsula during the evening, after a very mild start to the day with overnight temperatures holding in the 60s.
Wednesday morning should begin warm and somewhat humid, with the beaches staying cooler than inland communities. Through much of the day, areas farther south and east, including Sussex County, are expected to remain on the warmer side of the front longer than locations to the north, allowing temperatures to climb well into the upper 70s and possibly the 80s inland, while coastal communities stay cooler.
The greatest weather concern arrives Wednesday afternoon and especially Wednesday evening, when the chance for showers and thunderstorms rises as the front moves across Delmarva. Forecasters say a few storms could become strong, with damaging wind the main threat. Heavy downpours could also lead to isolated flooding in spots where storms repeatedly move over the same area.
By late Wednesday night into early Thursday morning, the front is expected to settle south of the area, bringing cooler and more stable conditions. Skies are likely to remain mostly cloudy, and a few light showers or areas of drizzle may linger into early Thursday. Temperatures by daybreak Thursday should fall back into the 50s across parts of Delmarva, including Sussex County, after the warm and unsettled weather from earlier in the day.
For beach communities, the overall message is to expect a breezy, cooler turn by early Thursday after a warm Wednesday. Residents and visitors should keep an eye on the forecast through the day Wednesday, especially for evening plans, when storms are most likely to affect southern Delaware
