While a flood watch for the region has been lifted on Saturday evening, humid temperatures and scattered showers will persist overnight and into Sunday.
WTOP Meteorologist Mike Stinneford said that the potential for heavy showers will wind down overnight, but Sunday will remain unsettled, with scattered showers and thunderstorms. Highs will be in the 80s.
The warm weather will continue on Monday as there will be a mix of sunshine and fair-weather clouds with much lower rain chances. Humidity will ease and temperatures will remain in the low to mid-80s, making it a good day to be outside, taking a walk or walking your pet.
However, the humidity will increase a bit on Tuesday. Temperatures in the afternoon will rise to the lower 90s under mostly sunny skies.
