Summary:
A plume of mid-level moisture from the west provided the fuel for an afternoon and evening of scattered showers (and couple thunderstorms) over the High Country. The bulk of the activity occurred over the higher terrain of the Northwest Slope, Northern Mountains, and Grand Valley, and Central Mountains, where moisture coincided best with a passing disturbance. Further south, over the Southwest Slope, San Juan Mountains, and San Luis Valley, conditions remained mostly sunny and dry, with only one or two isolated, gusty showers.
East of the Continental Divide, mainly dry conditions won out during the daylight hours as scattered cumulus clouds bubbled, but resulted in mainly virga and gusty winds. A few showers and thunderstorms moved across the Northeast Plains, Palmer Ridge, and far northern Southeast Plains early this morning as the disturbance worked across the area. Gusty winds and periods of light-to-moderate rainfall were the result.
No flash flooding was reported yesterday. For a look at precipitation estimates in your area, please see the State Precipitation Map below.

The map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE) across Colorado. The map is updated daily during the operational season (May 1 – Sep 30) by 11AM. The following six layers are currently available: 24-hour, 48-hour and 72-hour total precipitation, as well as maximum 1-hour, 2-hour and 6-hour precipitation over the past 24 hour period (to estimate where flash flooding may have occurred). The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. The accumulation ending time is 7AM of the date shown in the bottom right corner. Also shown optionally are fire burn areas (post 2012), which are updated throughout the season to include new burn areas. The home button in the top left corner resets the map to the original zoom.
