SPM 05-10-2021: Calm Before the Storm

Issue Date: Monday, May 10, 2021
Issue Time: 9:15 am MDT

Summary

Much of the eastern half of the state received some measurable precipitation yesterday, thanks to the widespread, stratiform rainfall. Some areas lucked out more than others, especially along the Northern Front Range and Urban Corridor, where a consistent 0.2” – 0.4” fell in Larimer and Boulder counties according to CoCoRaHS observers and SNOTEL sites. The western half of the state remained dryer,but still picked up some moisture, which helps with the ongoing fire danger and all red flag warnings for the region have since expired. Due to the low intensity nature of yesterday’s precipitation, flooding was not reported on Sunday. For rainfall estimates in your area, check out our State Precipitation Map below.

Colorado is no stranger to wild swings of weather, especially in the springtime, and yesterday marked the start of a much wetter few days for the state. Heavy snow is forecasted for the central mountains, but there’s potential for even lower elevations to get some snow or wintry precipitation along with it. The SPM will be updated daily to reflect total moisture received with this system and exciting snowfall totals.

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.
