Flash Flood Prediction Program

Time: 1239 PM Thu September 12, 2024 Forecaster: Tim Tonge ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- Potential final 90 degree day of 2024, dry and windy The dry slot of a potent storm system over Wyoming and Montana is placed firmly over Colorado today. Upper-level flow is out of the southwest, and hot, dry, desert air has cleared out available moisture from the District, and no storms are expected today as a result. Temperatures across the District are likely to hover at or just below 90 this afternoon. As the aforementioned storm system pushes east, a surface low will deepen over southeastern Wyoming, which in turn will cause winds to pick up across much of Colorado today. Much of the District will see consistent winds of 15-20mph through the afternoon and evening with gusts to 40mph possible, especially over the Palmer Divide and in eastern portions of the District. Winds will calm after sunset. Large wildfires east of Los Angeles have produced a plume of smoke that is currently draped across the majority of the desert southwest. Under southwesterly flow, this smoke will arrive in Colorado around sunset and produce hazy conditions and poor air quality overnight. STORM RAINFALL POTENTIAL AND DURATION: No rainfall is expected in the District today. A LOOK AHEAD: The thunderstorm season has essentially come to an end, with the only upcoming chances for rainfall near the District coming Sunday, and even Sunday the storms appear highly isolated and contained to the high country outside the District. Otherwise, a pleasant stretch of fall days is ahead until a shift in the weather pattern brings back a chance of rainfall and cooler temps mid/late next week.
