Heavy Precipitation Outlook
Flash Flood Prediction Program

Gust Front creating Minimal Chances for the District.
Dry air over the District is currently being modified by a gust front moving in from the east, bringing in moister conditions. PWAT values still remain around 0.50", but dew points are increasing to the upper 30s to low 40s, allowing the possibility of precipitation across the District. Storms still look unlikely within the District as they struggle over the higher elevations, however minimal chances remain. If a shower develops, it looks to produce a trace to 0.05". Precipitation chances increases towards the southern end of the District.
STORM RAINFALL POTENTIAL AND DURATION: If a shower does develops will produce Trace-0.05" of rainfall in 10-30 minutes. Stronger showers or an isolated thunderstorm will produce 0.05"-0.10" in 10-30 minutes.

WORST CASE SCENARIO: A strong/stationary shower/thunderstorm, or training of showers/thunderstorms, could be capable of producing 0.25" of rainfall total in 60 minutes or less.

A LOOK AHEAD: A secondary cold front moving in overnight will dry out the District even more, and should result in dry conditions tomorrow.
