Heavy Precipitation Outlook
Flash Flood Prediction Program

HOT WITH ISOLATED HIGH-BASED AFTERNOON THUNDERSTORMS
-SW upper-level flow remains in place today leading to slightly warmer temperatures this afternoon with highs in the low to mid 90's across the plains with upper mid to 80's along the foothills. Winds will pick up this afternoon from the S/SW with gusts up to 35mph favoring eastern portions of the District.
-A few weak showers and isolated high-based thunderstorms will develop this afternoon and could continue to around sunset. Due to limited surface moisture the storms that develop today will produce minimal rain and gusty winds.
-Conditions will dry out completely into the overnight as low temperatures drop into the upper 50's to low 60's. Wednesday will be hot and dry throughout the day and evening.
STORM RAINFALL POTENTIAL AND DURATION: High based showers and weak thunderstorms will produce a trace to 0.10" of rain.

A LOOK AHEAD: A cold front moves through the region Wednesday evening resulting in cooler daytime temperatures in the 70's with a increased chance for afternoon and evening rain showers/isolated thunderstorms Thursday and Friday. A better chance for rain showers/isolated thunderstorms Saturday, although the threat for heavy rainfall remains minimal at this time.
