Flash Flood Prediction Program

Isolated Showers and Thunderstorms this Afternoon and Evening
A series of upper-level disturbances propagating across the Intermountain West will support typical springtime showers and thunderstorms along the District this afternoon and evening. Afternoon temperatures will reach the mid 60s with dewpoints in the low 30s. Isolated showers are possible this afternoon and evening. Storm motion today will be quick, limiting point rainfall amounts.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers will produce light rainfall of up to 0.10” total in 15-30 minutes.

WORST CASE SCENARIO: A strong thunderstorm has the potential to produce up to 0.20” total rainfall 15-30 minutes.

A LOOK AHEAD: A warming trend begins tomorrow as the cool airmass exits the High Plains. Temperatures will reach the upper 60s to low 70s with winds from the south between 10-20 mph, gusts as high as 30 mph. Chances for isolated showers and thunderstorms will improve during the afternoon and through the evening. Minimal precipitation is expected. Saturday will be similar with afternoon temperatures in the upper 60s to low 70s and winds from the south at 10-15 mph, gusts up to 20 mph.
