| Storms have currently developed over the higher elevations, around the Continental Divide, and will move into the District within the next hour or two. Storm motions will be moving NW to SE at 15-20 mph, which should limit point rainfall amounts. Stronger storms will produce outflow boundaries and could cause erratic movement, lower speeds, increasing point rainfall amounts for the District. The biggest threat will be this afternoon and early evening will be a quick 0.50-0.60” in 10-30 minutes rather than any long lasting rainfall. Storms will continue to impact the region over the next several hours with a few lingering showers in the early evening. Skies will gradually clear just after sunset with temperatures dropping into the low 60s in the plains and mid to upper 50s in the foothills. |
WORST CASE SCENARIO: A slow-moving, strong thunderstorm may be capable of producing up to 1.25” or more in 30 minutes or less.
