- | Unseasonably warm temperatures will continue over the District today with readings in the upper 80's to lower 90's over the plains. Somewhat drier air will move overhead and reduce the thunderstorm coverage today. There will still be isolated afternoon thunderstorms but the heavier rain threat pushes eastward with storms that develop today generally producing light rain and gusty winds. |
- | By early afternoon thunderstorm activity will initiate over the higher terrain to the west. Upper level steering winds will push the storms eastward onto the I-25 corridor by 2 or 3pm. Isolated storm coverage is then expected until around sunset. Most storms will trend on the weaker side but a stronger thunderstorm will be capable of producing brief moderate to possibly heavy rain. |
- | After sunset as daytime heating is lost any shower or thunderstorm activity will diminish with dry conditions for the overnight period. |
WORST CASE SCENARIO: Surface moisture remains higher than anticipated resulting in a strong thunderstorm with the potential for heavy rainfall of 0.3-0.8" in 10-30 minutes.
A LOOK AHEAD: Temperatures on Tuesday will warm well into the 90's over the plains with 80's in the Front Range foothills. Thunderstorm activity lifts northward with dry conditions expected south of the CO/WY border over the plains with possibly a higher elevation afternoon thunderstorm. Hot and dry weather then looks to continue through the rest of the work week with a chance for thunderstorms returning over weekend.
