MESSAGES WILL BE ALLOWED TO EXPIRE AT 10:00PM
-Message 1's will be allowed to expire at 10:00 PM as the threat for heavy rainfall has come to an end.
-A few isolated showers and weak thunderstorms will be possible over the next couple of hours before conditions completely dry out for the overnight period. Any shower activity should remain minimal with a few areas of isolated moderate showers or thunderstorms possible, although the threat for any additional heavy rainfall has ended due to the lack of daytime heating and a relatively stable atmosphere in place over the region at this time.
-Best chances for an isolated shower or thunderstorm will be through 11:00 PM, with a very slight chance for any additional shower activity after midnight and will favor eastern areas of the District.
STORM RAINFALL POTENTIAL AND DURATION: Isolated rain showers and weak thunderstorms will produce a trace to 0.2".

WORST CASE SCENARIO: A stronger thunderstorm, or stationary thunderstorm will produce 0.2-0.4" in 60 minutes.
