Flash Flood Prediction Program

-	Message 1's continue valid for Adams, Arapahoe, Denver, Douglas and Jefferson Counties until 8pm this evening, however the threat for heavy rainfall is diminishing.
-	A gust front moved through the District from NW to SE and generated a few isolated thunderstorms over eastern areas of the District but did not produce much additional activity. Now that this gust front has moved through we are lacking a trigger for new storms and the threat for thunderstorms is lowering with temperatures in the 60's to lower 70's over the plains.
-	A weak wave to the N may still be able to produce weak to moderate thunderstorm activity later this afternoon and early evening as it moves into the District.

STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak thunderstorms will produce a trace to 0.2" in 10-30 minutes. Moderate to strong thunderstorms will have the potential to produce 0.2-0.6" in 10-30 minutes.

WORST CASE SCENARIO: A large or slower moving thunderstorm may result in up to 1.2" of rain in 45-60 minutes.
