DELMARVA - Sussex County residents should brace for a soggy stretch of weather starting early Friday morning and continuing through early Sunday, as a slow-moving system brings rounds of rain, scattered thunderstorms, and muggy conditions.
An area of low pressure riding along a stationary front will arrive Friday morning, triggering the first of multiple rounds of showers across the region. Rainfall is expected to increase in coverage and intensity throughout the day Friday, with the heaviest periods likely occurring during the evening and overnight hours.
Though thunderstorm chances remain isolated, any stronger cells that do form may produce locally heavy rain and gusty winds. Dew points in the mid- to upper 60s will make for an oppressive atmosphere, and moisture-rich air could support rainfall rates capable of causing minor flooding in low-lying or poorly drained areas.
By Saturday morning, the initial low-pressure system will begin to exit, but the front over the Mid-Atlantic will lift north as a warm front, drawing in additional moisture and instability. A second, weaker disturbance may follow Saturday afternoon, renewing the threat of more showers and isolated thunderstorms. While the threat for severe weather remains minimal, forecasters are monitoring for potential pockets of heavier rain.
The Weather Prediction Center has placed the region under a Marginal Risk for excessive rainfall through Saturday night, meaning isolated flooding can’t be ruled out—especially in areas that see repeated downpours.
Temperatures will remain subdued under cloudy skies and rainfall, with highs on Friday and Saturday in the upper 70s to low 80s inland and lower 70s closer to the coast. Overnight lows will hover in the upper 60s to low 70s, thanks to persistent cloud cover and high humidity.
By early Sunday morning, the low pressure responsible for the unsettled weather is expected to shift toward the northeast, allowing rain to gradually taper off. However, additional showers and storms could redevelop later Sunday into Monday as moisture lingers over the Mid-Atlantic.
Travelers and outdoor event planners are advised to monitor weather updates and prepare for wet conditions through early Sunday. Rain gear will be essential, and those in flood-prone areas should remain alert.
