SPM 05-25-2022: Last Day of Rain and Snow before Dry Weather Returns

Issue Date: Wednesday, May 25th, 2022
Issue Time: 9:45 AM MDT

Summary:

The upper-level trough responsible for our weather on Monday remained slow to depart the region on Tuesday, producing the final day of a prolonged stretch of cool and wet weather across the state. Once again, large-scale ascent and northerly upslope flow combined to produce rain and snow east of the divide. Rainfall amounts along the urban corridor were generally 0.25” or less, while the southeastern plains saw heavier rainfall totals approaching and exceeding 1”, especially Bent, Prowers, and Baca counties. A CoCoRaHS observer in Holly near the Kansas border reported 1.08” of rainfall, which was the highest precipitation total across the state.

Snowfall yesterday was confined to the high country along the urban corridor, where the previously dwindling snowpack was once again replenished with fresh powder. The central Front Range saw over half a foot, with 8.6” reported by CoCoRaHS observers near both Nederland and Dumont. The rest of the high country saw a trace to a few inches at most. The fresh snowpack on Pikes Peak was easily visible in the clear skies this morning behind yesterday’s departing storm system:

Precipitation rates on Tuesday were generally light to moderate. Several streams, creeks and rivers across the state, most notably the Arkansas River at Las Animas, are running above normal after the precipitation the past few days, but none are in flood stage.

There was no flooding reported yesterday. For precipitation estimates in your area over the last few days, 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.
