DELMARVA - Get ready for another unsettled weekend weatherwise. A stalled out front will be the focus for showers and storms throughout the weekend. Have a plan B for Dad with rain in the forecast for Sunday. Â
An area of low pressure riding along a stationary front will arrive later today, triggering the first of multiple rounds of showers and thunderstorms 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. High temperatures in the mid 80s, with 70s and 80s at the coast.
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.
Showers and storms wind down around sunset with mild and muggy conditions with temperatures in the 70s. By morning, lows only near 70 with mainly cloudy skies.
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. High temperatures in the 70s are expected.
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.
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. Have alternate plans with Dad, with cool and wetter weather. Highs Sunday only in the low 70s.
Travelers and outdoor event planners are advised to monitor weather updates and prepare for wet conditions throughout the weekend. Rain gear will be essential, and those in flood-prone areas should remain alert.
