Tonight, under partly cloudy skies, the temperatures will range from the lower 60s by the mountains to around 70 degrees in D.C.
On Sunday, we quickly bring storms back to the region, but not until the afternoon hours. If you plan to head out for an early service, the weather will cooperate; however, by lunchtime, a line of storms is forecast to develop in Western Maryland and move east throughout the afternoon. Of course, there can always be changes in the timing of when any storm arrives in your neighborhood, but right now, the primary time to see storms impact the largest population centers throughout the DMV would roughly be between mid-afternoon and mid-evening (3-9 PM). The main hazard with any storm would be damaging winds, but isolated hail and even a brief tornado can’t be ruled out at this time. The one thing that I do feel most confident about is that widespread flooding would be very limited, just based on the progressive movement of any storm.
By Sunday evening, a “cool” front will move across the region and out to sea, allowing cooler and drier air into the area and bringing the threat of severe thunderstorms to an end. Overnight lows heading into Monday morning will look to range from the low 50s in Western Maryland to the mid-60s from the Beltway to the Bay.
Variably cloudy skies, along with a cool and dry pattern early in the week, will be followed up by a return to warmer temperatures, increased humidity levels, and potential for strong thunderstorms, especially Thursday.
