Issue Date: Tuesday, June 28th, 2022
Issue Time: 9:45 AM MDT

Summary:

Similar to yesterday, most precipitation was confined to the mountains and southern portion of the state- the Northwest Slope, Northern Mountains, and Grand Valley on the western side of Colorado all saw very little or no rainfall. In the southwest, totals were lower than those from yesterday’s activity- up to almost 1.0” in Pagosa Springs with reports of hail, while high observations from other areas were generally between 0.2”-0.45”. The San Luis Valley and Southern Mountains also received up to 0.45”. A flash flood warning was issued southwest of Colorado Springs in the Sangre de Cristo Mountains, and a severe thunderstorm warning was issued directly southwest of Colorado Springs earlier that afternoon. Despite this, Pueblo and Colorado Springs received little to no rainfall. In the Southern Plains, areas received 0.1″-0.5” from steady rain yesterday morning.

In the Central Mountains, most areas were dry or saw less than 0.1”, but brief storms produced up to 0.62” in some locations. There was a flash flood warning issued east of Glenwood Springs yesterday afternoon over the Grizzly Creek burn scar that caused I-70 to be shut down overnight. However, no flooding was reported and the highway is now back open. There was also a Flood Advisory issued over a western part of the Cameron Peak burn scar, but no flooding was reported there as well.

The Front Range received up to 0.32” of precipitation near Idaho Springs in the mountains, and up to 0.35” of rainfall north of Estes Park. Additionally, north of Fort Collins, there was a short evening storm that created up to 0.28” of rainfall. Reports from the mountains and foothills outside of these higher observations, however, generally reported under 0.1″ of rainfall.

There was no flooding reported yesterday. For precipitation estimates in your area, check out the map below.

Note: The Grand Junction radar is down for maintenance. This will impact the accuracy of QPE, especially in the southwestern portion of the state.

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 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.
