SPM 06-20-2020: Widespread Showers and Thunderstorms East of the Divide

Issue Date: Saturday, June 20th, 2020
Issue Time: 9:00 AM MDT

Summary:

It was another cool day across Colorado thanks to an upper-level disturbance swinging across the state. West of the Continental Divide, the disturbance provided enough support for scattered showers/weak thunderstorms. East of the Divide, enhanced moisture provided the fuel for widespread showers and thunderstorms; a few storms were strong, especially over the Southeastern Plains and Raton Mesa, where copious amounts of small hail were reported from one supercell in particular that rumbled along the NM/CO border. The only severe storm report coming from 7 miles North of Brandon (Kiowa County) where 1.75-inch diameter hail was reported. As far as rainfall reports are concerned, the following “top reports” come from CoCoRaHS observers (as of 7:15 AM):

0.74 inches: Las Animas County
0.59 inches: Weld County
0.50 inches: El Paso County
0.49 inches: Boulder County
0.43 inches: Kit Carson County
0.41 inches: Lincoln County

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 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. 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.
