Flash Flood Prediction Program

-	A potent trough of low pressure will move through today producing strong S/SW winds of 15-30mph with gusts to 40-50mph or more possible. Temperatures will be held down today due to cloud cover with highs over the plains in the 80's to possibly around 90 if we get some periods of sun.
-	Isolated to widely scattered rain showers will move through this morning with chances for thunderstorms by around noon or before. There will then be a round or two of thunderstorms that move through during the afternoon with conditions expected to be drying out by 7 or 8pm.
-	Thunderstorms that develop today may become strong to severe with moderate to brief heavy rainfall, gusty winds, large hail and frequent lightning. Fast storm motions from S to N at 30-35mph will help to reduce point rainfall amounts from a single storm with training of thunderstorm cells potentially producing a longer period of moderate to heavy rain that could lead to excessive runoff.

STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak to moderate thunderstorms will produce a trace to 0.3" of rain in 10-30 minutes. Strong thunderstorms will have the potential to produce 0.3-0.8" in 10-30 minutes.

WORST CASE SCENARIO: Training of strong thunderstorm cells may result in up to 1.5" of rain in 60 minutes or less.

A LOOK AHEAD: Remaining breezy on Sunday but conditions will be dry area wide under sunny to mostly sunny skies.
