Flash Flood Prediction Program

-	Warmer and drier weather arrives along the Front Range Monday, as a flat ridge of high pressure builds into the Rockies. Mostly-sunny skies will help daytime temperatures climb into the low 80s today.
-	Lingering moisture will maintain the threat for isolated showers and thunderstorms this afternoon and early evening, most numerous over the foothills, Palmer Divide, and Cheyenne Ridge. With limited low-level moisture in place, today’s showers and storms will produce little measurable rainfall, with brief gusty winds being the main threat.
-	Today's showers and storms will track to the ESE around 15-20mph, with the best chance for a storm over the District occurring between about 2pm-6pm.

STORM RAINFALL POTENTIAL AND DURATION: Showers and thunderstorms will produce rainfall amounts between Trace-0.20" in 10-30 minutes.

WORST CASE SCENARIO: A stronger thunderstorm produces rainfall between 0.20-0.40" in 30-60 minutes.

A LOOK AHEAD: Conditions remain similar on Tuesday, with highs in the low 80s expected once again along with plenty of sunshine. A weak ripple arrives from the W during the afternoon, which may lead to a slight uptick in high-based shower and storm activity along the Front Range.
