SPM 05-03-2022: Soaking Rain and Even Snow for Northern and Eastern Colorado

Issue Date: Tuesday, May 3rd, 2022
Issue Time: 10:10 AM MDT

Summary:

The low-pressure system and associated cold front impacting the state’s weather over the last few days continued its eastward progression yesterday. This allowed for morning rain, and even snow, for much of the northeast quadrant of the state. As the day progressed, a general drying trend from west to east followed the exiting system, with precipitation largely ending by late afternoon. Available moisture at the surface from a few days of precipitation and cooler temperatures allowed for fog formation overnight, which has lingered into this morning for the Northeast Plains, Palmer Ridge, and Urban Corridor.

Precipitation totals from yesterday are most impressive in the Northeast Plains, including 1.57 inches from a CoCoRaHS observer in Wray (Yuma County), who also noted  “Nice rain turning to snow about 10:30am. Snow melted about 4pm. Heavy frost and fog overnight.1.25 inches was reported in Sterling (Logan County) and 0.96 in Burlington (Kit Carson County).

Precipitation totals were more modest to the west along the Urban Corridor and Front Range Mountains. QPE, as seen in the map below, has precipitation totals around 0.25 inches; however, CoCoRaHS and other local gauge networks reports generally range between only 0.0-0.15 inches across the Urban Corridor, with values approaching 0.25 on the eastern edge of the Front Range Mountains.

There were no flood reports yesterday. For rainfall estimates in your area, check out the MetStorm Live QPE 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.
