| West-northwesterly flow aloft has developed broadly across Colorado as an upper-level disturbance traverses the Northern Plains. As a result, down sloping winds will help to suppress thunderstorm activity today on the Plains. This morning will be sunny followed by high temperatures in the upper 80s to low 90s and dew points in the low 40s. Scattered showers and thunderstorms will develop over the mountains this afternoon. A few storms will move east of the mountains in the late afternoon and evening. Lightning activity will be limited, but weak showers may produce localized gusty winds with little rain. |
WORST CASE SCENARIO: Training thunderstorms have the potential to produce 0.40” to 0.80” in 60 minutes.
A LOOK AHEAD: Conditions will be similar this weekend, with highs in the upper 80s to low 90s and a slight chance for isolated showers and thunderstorms. On Sunday evening, an upper-level disturbance and its associated cold front will bring a chance for scattered showers and storms across the Front Range Urban Corridor.
