- | An upper level disturbance over western Colorado this morning will move through the District this afternoon and produce scattered showers and thunderstorms some of which may be capable of producing brief heavy rainfall, gusty winds and hail. Temperatures will reach the 70's over the plains before cloud cover increases this afternoon. |
- | Thunderstorms will initiate over the foothills before noon and then spread eastward onto the plains. Storms will be relatively fast moving from SSW to NNE at 25-35mph helping to reduce point rainfall amounts. One to three rounds of storms are likely through the early evening. |
- | Surface moisture has increased from previous days with dew points expected to be in the mid 40's to around 50. The modest surface moisture will allow for some storms to produce brief heavy rainfall which may lead to excessive runoff. |
WORST CASE SCENARIO: A slower moving strong thunderstorm or training of strong thunderstorm cells may result in up to 1.3" in 45-75 minutes.
A LOOK AHEAD: Drier air aloft will move into Colorado on Saturday lowering the threat for thunderstorms activity but there will still likely be isolated afternoon thunderstorms favoring the foothills. Temperatures will continue to lower with highs on the plains in the 60's.
