Issue Date: Sunday, June 6, 2021
\nIssue Time: 9:20AM MDT<\/p>\n

Summary:<\/h3>\n

Thunderstorms began to develop in the late morning at high elevations as moisture was funneled in Western Colorado around a high-pressure system situated southwest of the state. Widespread<\/span> thunderstorm activity increased in the afternoon bringing light, but much needed, precipitation to the west, including 0.11” in East Grand Junction, and similar 0.10-0.15 inch totals in the Southwest Slope and San Juan Mountains according to CoCoRaHS<\/span> observers. For additional rainfall estimates in your area, check out the State Precipitation Map at the bottom of this post. <\/p>\n

Several flood advisories or warnings were issued across the state over major burn areas, including flood advisories for the East Troublesome and Williams Fork burn areas, and flash flood<\/span> warnings for the Cameron Peak and Spring Creek burn areas. These warnings were issued after Doppler radar indicated heavy rain due to thunderstorms. However, no additional flood reports were made at these locations (or elsewhere in Colorado). For the burn areas, a lack of reports could simply be due to their remote locations, which limit human observations of flooding. <\/p>\n

As the day progressed to the evening, some storms began to spill over from the Front Range and into the Urban Corridor. A severe thunderstorm<\/span> warning<\/span> was issued for Castle Rock and the surrounding areas after radar indicated quarter-sized hail. Again, precipitation totals with these storms were light, but they did put on quite a lightning show, as seen in many social media posts, including the following taken in Centennial<\/a>. <\/p>\n

\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE<\/span>) 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<\/span> 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.
