Time: 942 AM Thu August 1, 2024 Forecaster: Laura Smith ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- Smoky Skies with slight chances for Isolated Storms. Smoke from several wildfires along the Front Range foothills will inundate the Urban Corridor today as light upper-level winds carry smoke plumes onto the plains. Smoke aside, hot conditions will continue as afternoon temperatures reach the upper 90s. A few locations may reach or exceed 100°F today (which is about 10°F above normal). Dewpoints will be around 40°F, with precipitable water (PWAT) values around 0.65”. These conditions will support a slight chance for isolated showers and thunderstorms this afternoon and evening, primarily across the foothills and Palmer Divide. STORM RAINFALL POTENTIAL AND DURATION: Showers and thunderstorms today have the potential to produce up to 0.10” in 10-30 minutes. WORST CASE SCENARIO: A slow-moving stronger thunderstorm may be capable of producing 0.20” or more in 30 minutes or less. A LOOK AHEAD: The long-range forecast remains somewhat underwhelming with the arrival of an upper-level disturbance. Atmospheric moisture will increase slightly, resulting in PWAT values up to 0.75” and dew points in the mid 40s. No significant precipitation is expected with this pattern, but there is a slight chance for isolated showers and storms Friday and Saturday.
