Summary:
Daytime heating and a bit of mid-level moisture acted in concert to drive the development of scattered showers and a few embedded thunderstorms yesterday. Activity kicked off during the late morning hours over the High Country, with eastern Colorado following suit around lunch time. Most of the activity over the High Country was confined to the Front Range, Southeast Mountains, Northern Mountains, Northwest Slope, and Central Mountains, where mid-level moisture was best, relatively speaking. East of the mountains, the Urban Corridor, Northeast Plains, and Palmer Ridge enjoyed scattered showers and a couple thunderstorms, while the Southeast Plains and Raton Ridge remained dry.
Due to a lack of good surface moisture, activity yesterday was high-based, and much of the precipitation that fell evaporated before reaching the surface. This process shunted rain rates and rain totals, and most locations received less than 0.1 inches of rainfall. 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 vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas. The home button in the top left corner resets the map to the original zoom.
