Time: 957 AM Sat July 13, 2024 Forecaster: Tim Tonge ------------------------- Heavy Precipitation Outlook Flash Flood Prediction Program ------------------------- Very hot with isolated showers in southern foothills Relatively stationary high pressure remains over the Four Corners region today, bringing another solid chance for triple digit temperatures across the District. The District will continue to be almost entirely dry, with a slight chance for isolated, high based, gusty showers in the southern foothills in the late afternoon. Storms are unlikely to drift to lower elevations, but those that do will favor Boulder, Jefferson, and Douglas counties. Moisture slowly begins to fill back in to the region over the course of the next few days. STORM RAINFALL POTENTIAL AND DURATION: Thunderstorms over the foothills today have the potential to produce up to 0.10” in 10-30 minutes. WORST CASE SCENARIO: A slow-moving thunderstorm may be capable of producing 0.20" or more in 30 minutes or less. A LOOK AHEAD: Similar pattern tomorrow with triple digits temperatures and isolated, high-based, gusty storms, mostly contained to the foothills. Moisture slowly returns as the work week arrives, driving increased chances for storms Monday.
