SPM 06-29-2022: Isolated Storms for Southwest Colorado, Hot and Dry for Rest

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

Summary:

Building high-pressure to the west of Colorado allowed for mostly clear skies and limited rainfall potential yesterday. Still, some isolated high-based showers and storms were able to develop in the early afternoon in the Southwest Slope, San Juan Mountains, and Central Mountains. As the afternoon progressed, discrete but widely scattered cells extended into the Northern Mountains, Front Range, and Southeast Mountains as well.

In Western Colorado, daily maximum dewpoint temperatures increased the further south in the state. Dewpoints in the 40s were seen in the Grand Valley and Central Mountains, compared to mid-to-upper 50s for the Southwest Slope and San Juan Mountains, which corresponded with the highest precipitation totals in the state yesterday.

One CoCoRaHS observer in Pagosa Springs reported 0.84 inches yesterday, though other observations around town are between 0.04-0.28 inches. A quick storm west of Durango dropped 0.64 after noon, as seen in the hyetograph below from La Plata-Cherry Creek Ditch near Hesperus. The isolated nature of yesterday’s storms is also seen in the QPE below, with pockets of higher accumulations limited to higher elevations of the San Juan, Central, and Southeast Mountains.

The eastern half of the state remained hot and dry, with temperatures across the Urban Corridor, Northeast Plains and Southeast Plains reaching into the 90s. 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.
