Message 1’s will continue to be valid until 10pm as the threat of heavy rainfall remains.

After a round of moderate to strong showers and thunderstorms across the District, with skies clearing behind. Another round of showers will be possible later this evening, likely between 8-10pm. Some sunshine and dew points in the 50s will keep the threat for moderate to heavy rainfall into the evening hours, favoring the foothills at this time.

Once this final round of showers moves through, a very slight chance for a few lingering showers after 10pm with skies gradually clearing through the overnight. Temperatures overnight will drop into the low to mid 60s for the plains with mid to upper 50s along the foothills.
