DELMARVA - Sussex County residents should brace for an active stretch of weather as a potent cold front sweeps across the region Tuesday night into early Wednesday.
Clusters of heavy thunderstorms will develop ahead of the front and are expected to move into Delaware overnight. These storms carry the potential for locally damaging wind gusts and torrential rainfall, with the greatest flooding risk occurring during the late evening and overnight hours. Forecast models indicate that some storms could produce between one and three inches of rain in a short period, with isolated amounts up to four inches possible if storms train over the same area.
As the front edges eastward, showers and thunderstorms will linger into Wednesday morning, particularly across southern Delaware. Conditions will gradually improve through the afternoon as skies begin to clear from west to east. High temperatures on Wednesday will reach the 80s, with areas seeing more sunshine warming into the upper 80s.
By Wednesday night, high pressure will begin to build south and west of the area, bringing drier and quieter weather. Overnight lows will dip into the 60s under clearing skies.
Thursday is expected to be mostly dry with warm temperatures climbing into the mid to upper 80s. A weak cold front may pass near the area later Thursday afternoon and evening, sparking a few showers or an isolated thunderstorm mainly north and west of Sussex County.
Looking ahead to Friday and the start of the weekend, high pressure is forecast to settle over the region, ushering in pleasant conditions with seasonable temperatures in the 80s and lower humidity—a welcome respite after the unsettled weather midweek.
Residents should monitor forecasts and be prepared for changing conditions Tuesday night into Wednesday, especially in areas prone to flooding.
