Internal Message Status
Flash Flood Prediction Program

MESSAGES WILL BE ALLOWED TO EXPIRE AT 9:00PM
-Messages will be allowed to expire at 9:00pm as the threat for heavy rain has ended.
-Strong to severe thunderstorms moved through the District this afternoon with mostly moderate to large hail impacting several regions before moving out onto the eastern plains this evening. As these storms propagate eastward, a more stable air mass has moved in behind resulting in overcast skies with a small chance of an additional light shower through the overnight hours and into Sunday morning.
-Any additional rainfall will be light as temperatures have cooled this evening with the loss of daytime heating. Heavy rainfall and hail is no longer a threat.
STORM RAINFALL POTENTIAL AND DURATION: Isolated rain showers and possibly a weak thunderstorm will produce a trace to 0.10"

WORST CASE SCENARIO: A slow moving shower or weak thunderstorm will produce 0.1-0.3" in 30-60 minutes.
