Isolated to Scattered Showers and Thunderstorms Today and This Evening
Elevated moisture levels following last nights cold front will support chances for showers and thunderstorms today. Afternoon temperatures will be in the low to mid 50s with dew points in the low 30s. Slight chances for isolated showers this morning will gradually improve throughout the day. Storm motions will be quick around 25 mph, limiting point rainfall amounts. Isolated storms are possible overnight, decreasing in coverage during the early morning hours tomorrow.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers will produce light rainfall of up to 0.10” total in 15-30 minutes.

WORST CASE SCENARIO: Stronger showers blowing off the foothills have the potential to produce up to 0.20” total rainfall 15-30 minutes.

A LOOK AHEAD: Chances for showers and thunderstorms continue Friday afternoon and evening with winds from the east between 5-10 mph and gusts up to 15 mph. This typical spring pattern continues into the weekend with chances for isolated to scattered showers and thunderstorms and warmer temperatures in the upper 60s to low 70s.
