Flash Flood Prediction Program

-	Message 1's will be allowed to expire at 8:00pm as the threat for heavy rainfall has come to an end. Strong to severe storms have moved well out onto the eastern plains this evening with cloudy and cool temperatures heading into the evening.
-	A few additional scattered showers/isolated thunderstorms could be possible this evening and through the overnight into Sunday morning. Any rain shower activity will typically produce a trace to 0.2" in 10-30 minutes, although a moderate rain shower or thunderstorm could have the potential to produce 0.2-0.4" of rainfall in that same timeframe. Storm motions will continue to be relatively brisk between 10-20mph from S/SW to N/NE helping limit any point rainfall amounts.
-	Cloudy skies will persist through the evening with overnight lows dropping into the upper 40's to low 50's on the plains with upper 30's to low 40's along the foothills. With excess surface moisture in place, expect a few areas of patchy fog tomorrow morning with partly sunny skies into the later morning hours. Temperatures tomorrow will reach the 70's to around 80, breezy, with another chance for afternoon rain showers/isolated thunderstorms.

STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will produce a trace to 0.2" in 10-30min. A weak to moderate rain shower/thunderstorm could produce 0.2-0.4" in 10-30 minutes.

WORST CASE SCENARIO: A slower moving thunderstorm or training of thunderstorms could produce 0.8" in 60-90 minutes.
