| A cold front will pass through the Front Range Urban Corridor keeping fall-like temperatures in place and will likely bring widespread rain showers and thunderstorms. Highs this afternoon will be stunted, only reaching the mid 70s for the plains with upper 60s to low 70s along the foothills. Showers and thunderstorms have initiated along the foothills and will increase in coverage over the next hour or so. Showers and thunderstorms become widespread between 4-6 PM. Chances of severe storms are very unlikely within the District as temperatures remain cool today, however, elevated available moisture will bring pockets of moderate to heavy rainfall which could potentially lead to some localized flooding under stronger storms. The peak timing for heavy rainfall will be between 4-8pm. Thunderstorm and heavy rainfall chances will likely dissipate by 8-9pm with widespread light to moderate showers dominating the area and continuing through the overnight. Overnight lows will dip into the low 50s for the plains with mid to upper 40s along the foothills. |
WORST CASE SCENARIO: Strong stationery, or training of thunderstorms has the potential to produce 1.00” to 2.00” in under 60 minutes.
