Summary:
A meandering upper-level low near the 4-corners region sent a couple weak disturbances across Colorado yesterday, triggering scattered showers and thunderstorms across the state. Generally speaking, the main plume of moisture resided well above the surface, with drier air beneath it, resulting in activity that produced gusty winds and periods of light-to-moderate rainfall. A couple storms were on the strong-to-marginally severe side east of I-25, but even these did not result in any flash flooding issues. The lone storm report of the day came from southwest Colorado, where 0.5 inch hail was reported with a stronger thunderstorm located 3 miles N of Mesa Verde National Park (Montezuma County).
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.
