SPM 05-30-2022: Showers and Storms, Strong Winds on Sunday

Issue Date: Monday, May 30th, 2022
Issue Time: 11:30 AM MDT

Summary:

Sunday saw precipitation statewide, with the highest totals across the northern half of the state generally along and north of I-70. An upper-level trough across the western U.S. provided steep lapse rates and modest instability, allowing showers and storms to develop along another front as it tracked southward across the region. There were numerous reports of strong winds and hail associated with the showers and storms, including thunderstorm wind gusts in excess of 60 mph near Alamosa and hail up to 0.75” diameter near Vail and Grand Junction. Below is a video of hail falling just outside of Denver in Lakewood:

Precipitation totals were generally confined to 0.25-0.50”, although amounts approaching and exceeding 1” were reported by CoCoRaHS observers in Garfield and Routt counties. A maximum of 1.22” was reported near New Castle. Several high elevation locations saw their precipitation in the form of convective snow showers, but totals were light with a maximum of 3.8” reported near Silverthorne.

Sunday also saw a continuation of high winds across the state outside of the thunderstorm activity. A non-thunderstorm wind gust of 83 mph was reported in Gunnison County near Wuanita Hot Springs! Several other non-thunderstorm gusts of 60+ mph were reported. As such, critical fire weather continued with Red Flag Warnings south of I-70.

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.
