Hot and humid weather continues across Delmarva today, with highs reaching the upper 80s to mid 90s and heat index values approaching 100 degrees in some locations. Showers and thunderstorms are expected to develop later today, with southern Delaware and portions of Maryland’s Mid-Shore under a Marginal Risk for severe weather

Delmarva is entering a prolonged stretch of hot and very humid weather that will continue through at least Tuesday. Daily chances for showers and thunderstorms will accompany the heat, with some storms capable of producing damaging wind gusts, torrential rainfall and localized flash flooding. A weak cold front Sunday may provide a brief break from the oppressive humidity before moisture surges back Monday and Tuesday. A stronger front could finally bring more noticeable relief by late Tuesday or Wednesday.

 

After an unseasonably warm weekend, Delmarva will experience a sharp weather shift as a strong cold front moves in Monday night. Slight risk for severe thunderstorms and heavy rain. Cooler, drier air returns Tuesday before another unsettled pattern arrives late week.
