Heavy Precipitation Outlook
Flash Flood Prediction Program

Isolated showers and thunderstorms this afternoon and evening
Cooler conditions are expected today following yesterday’s cold front. Afternoon highs will reach the mid to upper 80s followed by slight chances of afternoon to evening showers and thunderstorms. Dewpoints will be in the low 40s with precipitable water (PWAT) values around 0.70”. Storm motions will be from west to east, around 20-30 mph. Quick storm motions today will help limit point rainfall amounts, therefore any precipitation is expected to be relatively light. However, there is still a chance that clustering thunderstorms produce more meaningful rainfall in the District.
STORM RAINFALL POTENTIAL AND DURATION: Typical thunderstorms today have the potential to produce up to 0.25” in 10-30 minutes. Strong thunderstorms may produce up to 0.50” in 10-30 minutes.

WORST CASE SCENARIO: Thunderstorm clusters or complexes may be capable of producing 1.00” or more in 30 minutes or less.

A LOOK AHEAD: Upper-level winds will be westerly tomorrow, supporting mostly sunny skies with afternoon temperatures climbing into the 90s. Isolated showers and thunderstorms are possible during the afternoon and evening with the passage of another cold front.
