SPM 07-22-2022: Hotter and Drier, Less Coverage of Storms

Issue Date: Friday, July 22nd, 2022
Issue Time: 9:30 AM MDT

Summary:

The heat continued Thursday with rising heights and warming temperatures aloft as the upper-level ridge shifted slightly eastward. Drier air, especially near the surface, was also able to work its way into the state. Together, the warmer temperatures aloft and drier air helped to suppress both convective intensity and coverage for most of Colorado. Nonetheless, isolated storms developed over the high terrain by midday, especially across the southern Front Range and into Park County. Convection remained confined to the mountains and foothills, with cells dissipating if they tried to move out into the adjacent Plains. Precipitation amounts were generally T-0.20” for the high elevations and Urban Corridor, although an automated station northeast of Ft. Collins reported 0.52”.

Farther east across the eastern Northeast Plains, better low-level moisture persisted, and two cells were able to produce heavier rainfall. Rain gauge coverage is sparse, but QPE data suggests localized totals of 1-2” across portions of northeast Lincoln and southeast Yuma Counties.

No flooding was reported yesterday; if you observe flooding in your area, remember to use the “Report a Flood” page to make any flood reports when you can safely do so. For precipitation estimates in our area, check out the 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 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.
