A cold front yesterday evening brought cooler and more humid low-level air from the Great Plains into the Front Range. That should fuel some showers and thunderstorms this afternoon and evening. Many of us will likely get at least a brief shower, and a few spots will probably see a strong thunderstorm with heavy rain and hail. One of the most popular local-scale models (the HRRR) is suggesting that the heavy thunderstorms may stay south and east of Denver, but there is enough uncertainty that I think all of the Front Range should be prepared for the possibility of thunderstorms.
There should be another, but smaller, chance for thunderstorms Tuesday afternoon. Then a mainly dry and warm (but not very hot) week is in store for the Front Range. Very hot weather will likely be close by in the western U.S., including western Colorado valleys.
