Flash Flood Prediction Program

-	Another hot day with record breaking heat as we approach triple digits once again. The record high temperature today at DIA is 98 degrees set in 1989. We should be at or above that just after midday.
-	Similar to yesterday, a slight chance for high-based afternoon rain showers/isolated thunderstorms. With high temps and low-level surface moisture mixing out this afternoon the largest threat today will be gusty winds and the occasional lightning strike as most precipitation will struggle to reach the surface. Best chance for storms today will be from 2-8pm with a few lingering sprinkles to light rain after 8pm.
-	A cold front moves in overnight bringing breezy to gusty north winds through the evening and into Saturday morning. Overnight lows will drop into the low to mid 60's with a chance for patchy fog into Saturday morning.

STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will produce a trace to 0.1" in 10-30 minutes. A weak to moderate thunderstorm will produce 0.1-0.3" in 10-30 minutes.

WORST CASE SCENARIO: A slower moving moderate thunderstorm or training of weak to moderate thunderstorm cells have the potential to produce 0.3-0.6" in 45-60 minutes.

A LOOK AHEAD: A reprieve from the heat this weekend as cooler temperatures ascend on us from the north. A very slight chance for rain showers/isolated thunderstorms Saturday afternoon with no heavy rainfall threat expected. Saturday and Sunday will be cooler with temperatures in the low to mid 80's. Dry conditions are likely both Sunday and Monday with storm chances picking up into Tuesday.
