| - | Another hot and hazy day for Colorado as highs reach the low to mid 90's on the plains this afternoon with mid to upper 80's along the foothills. Colorado will continue to tap into monsoon moisture today resulting in another chance for isolated heavy rainfall this afternoon and evening. |
| - | Thunderstorms will develop over the mountains/foothills during the afternoon. Thunderstorm chances increase over the plains between 3-4pm with prime time from 4-10pm. Additional showers and weaker thunderstorms will remain possible through midnight. At least 1 round of thunderstorms is expected this afternoon, with a good chance for an additional round of rain showers/isolated thunderstorms in the evening, however, the initial afternoon round likely being the strongest and will have the best chance for heavy rainfall. |
| - | Relatively slow storm motions from W to E between 5-10mph will allow for extended periods of heavy rain under stronger storms. Storm motions may also become erratic or potential stationary at times due to outflow boundaries/gust front interactions. This behavior will also increase the chance for isolated heavy rainfall this afternoon. |
WORST CASE SCENARIO: A nearly stationary strong thunderstorm may result in up to 2.0" in 60 minutes or less.
A LOOK AHEAD: As the high-pressure ridge remains over the Central/Southwest US, Colorado will continue to tap into monsoon moisture through the weekend with afternoon/evening rain showers/isolated thunderstorm chances both Saturday and Sunday. The intensity of rainfall will hinge heavily on how much surface moisture can remain in place throughout the day with upper 40's to low 50's dew points projected Saturday, at least a low chance will remain for isolated heavy rainfall. Conditions dry out at the surface slightly on Sunday, however a very low threat will remain for isolated heavy rainfall at this time.
