Flash Flood Prediction Program

Time: 900 AM Tue June 8, 2021 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- HOT, SUNNY AND GENERALLY DRY - High-pressure holds over the region leading to unseasonably high temperatures once again as they reach the low to mid 90's on the plains with low to mid 80's along the foothills. - Most areas will remain dry today, with a very slight chance for a few high-based rain showers/isolated thunderstorms for the foothills, although the biggest threat today from any storms will be gusty winds and possibly a lightning strike or two. Very little precipitation will be possible as most will evaporate before reaching the ground, although a trace to a tenth of an inch cannot be completely ruled out if a moderate storm is able to develop. Best chance will be from 1-6pm with skies clearing through the overnight. - Low temperatures early tomorrow morning will reach the upper 50's to low 60's with another hot and dry day expected tomorrow. STORM RAINFALL POTENTIAL AND DURATION: typical high-based foothills rain/isolated thunderstorm with produce a trace-0.05" in 10-30 minutes. WORST CASE SCENARIO: A moderate thunderstorm is capable of producing 0.05-0.10" in 10-30 minutes. A LOOK AHEAD: Unseasonably hot and dry over the next several days with temperatures in the mid 80's to mid 90's across the plains under mostly sunny skies. Looks like the next chance for rain will not be until next week as a high-pressure ridge takes hold over the region through this weekend.
