Time: 835 AM Sat June 11, 2022 Forecaster: Justin Brooks ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- NEAR RECORD BREAKING HEAT WITH A VERY SLIGHT CHANCE FOR SCATTERED HIGH-BASED AFTERNOON RAIN SHOWERS/ISOLATED THUNDERSTORMS - High-pressure continues to dominate over the region today leading to near record breaking heat as high temperatures reach the upper 90's to 100°F this afternoon. The current record for today at DIA is 100°F set back in 2013. - With highs well into the 90's and dew points projected in the upper 20's to low 30's this afternoon will result in a very slight chance for a few scattered rain showers this afternoon and early evening. However, due to rather dry conditions at the surface, most if not all precipitation will struggle to reach the surface today resulting in a better chance for gusty winds rather than any rainfall. Best chance to see and high-based showers will be from 2-6pm with skies clearing into the evening. - Overnight will remain mild and dry with lows dropping into the low to mid 60's across the plains with mid to upper 50's along the foothills. STORM RAINFALL POTENTIAL AND DURATION: Typical high-based rain showers/isolated thunderstorms will produce 0-TR of rainfall in 10-30 minutes. A weak to moderate thunderstorm could produce a TR-0.1" of rainfall in 10-30 minutes. WORST CASE SCENARIO: A moderate to strong thunderstorm is able to develop and will have the potential to produce 0.1-0.4" in 45-60 minutes. A LOOK AHEAD: The heat will stay through the weekend as high temperatures are expected to remain in the 90's. A slight increase in mid to low-level moisture tomorrow will increase afternoon and evening rain shower/isolated thunderstorm chances, however the threat for heavy remain will remain minimal at best. Monday will be dry with continued heat as highs remain in the 90's. Similar conditions Tuesday with a slight chance for scattered afternoon rain showers/isolated thunderstorms.
