Flash Flood Prediction Program

-	All LIF's and Message 3's issued earlier have already expired and the remaining Message 1's will be allowed to expire at 10:00 PM as the the threat for heavy rainfall has ended for the day.
-	Strong and severe thunderstorms late this afternoon and evening resulted in heavy rainfall over a large portion of the District. These storms have since weakened and moved out of the area leaving only a chance for a few isolated light rain showers or possibly a weak thunderstorm through midnight.
-	With surface moisture still in place on Thursday, thunderstorms that develop in the afternoon and evening will continue to have the potential to produce heavy rainfall. With the heavy rainfall today it may not take as much rainfall tomorrow in saturated areas to produce excessive runoff.

STORM RAINFALL POTENTIAL AND DURATION: Rain showers and possibly a weak thunderstorm will produce a trace to 0.2".

WORST CASE SCENARIO: A moderate to briefly strong thunderstorm is able to develop with the potential to produce 0.2-0.6" in 10-30 minutes.
