SPM 09-01-2022: Wet Wednesday for Eastern Half of State

Issue Date: Thursday, September 1st, 2022
Issue Time: 11:50 AM MDT

Summary:

Wednesday featured more active weather across the state thanks to a shortwave trough moving into the region from Montana. Increased moisture over the eastern foothills and plains led to numerous showers and storms mainly along and east of the I-25 corridor, although isolated convection also impacted the southern San Juans. Rainfall amounts over this eastern half of the state were generally 0.50-1.00”, although locally higher amounts approaching and exceeding 1.5” are suggested by QPE data under the most intense storms. The heaviest widespread rain appears to have fallen along and south of the Palmer Ridge over the Southeast Plains; however, in the southern San Juans, an isolated total of 1.39” was recorded by a rain gauge just west of Durango.

Notable rainfall totals over the Southeast Plains include:

• 0.82” near Two Buttes
• 0.71” near Lamar
• 0.60” near Arapahoe

Farther west in the high terrain along the southern I-25 corridor, notable rainfall totals include:

• 0.98” near Beulah
• 0.75” near Trinidad
• 0.70” near Rye

In terms of severe weather, a Severe Thunderstorm Warning was issued just east of Colorado Springs, while 1” hail was reported near Seibert and a 53-mph thunderstorm wind gust was measured near Kit Carson. Right on the Colorado-Kansas border, local law enforcement reported a landspout tornado approximately 15 miles WSW of Saint Francis, KS.

Looking at the updated U.S. Drought Monitor released this morning, conditions are in better shape compared to one and especially three months ago. We’ve seen a complete elimination of drought conditions for central portions of the state, while extreme/exceptional drought conditions have been pushed and confined to the far southwestern and northeastern tips 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.
