DELMARVA - Residents across Sussex County should be prepared for intermittent showers and brisk breezes through late Friday and Saturday as a closed upper-level low continues to dominate weather patterns over the eastern U.S.
A closed H5 low spinning over eastern Canada will remain in place through Saturday, influencing conditions from the Northeast down into the Mid-Atlantic. This system will send several potent shortwaves through the region, the most impactful of which is expected to arrive Saturday.
For Friday evening, scattered showers will pass through the area, with a chance for isolated thunder. However, no severe weather is anticipated. Showers are expected to taper off overnight, leading to partly cloudy skies. West winds will remain breezy at 10 to 15 mph, with gusts up to 25 mph before diminishing to 5 to 10 mph overnight. Overnight lows will dip into the 40s, making for a chilly end to the day.
Saturday will mirror Friday’s conditions with partly to mostly sunny skies and additional scattered afternoon showers. Thunderstorms are not expected, and rainfall amounts will be light. High temperatures will reach into the 60s, and west winds will increase again, gusting between 20 and 25 mph.
Looking ahead to the remainder of the weekend and into Memorial Day, the region will enjoy a break from the unsettled weather. Upper-level ridging and a surface high will usher in more tranquil conditions. Sunday may bring a slight chance of showers overnight as another shortwave moves across Maryland and into the Delmarva Peninsula. Temperatures will remain a bit below average, with highs in the upper 60s to low 70s and overnight lows in the 50s.
As the new week begins, expect a brief stretch of dry weather Monday night, followed by increasing shower chances Tuesday into midweek. Temperatures will stay below average through Wednesday, before rebounding closer to normal by Thursday and Friday.
