SPM 07-28-2018: Smorgasbord of Weather Impacts

Issue Date: Saturday, July 28th, 2018
Issue Time: 9:30 AM MDT

Summary:

The atmosphere was primed yesterday to produce a myriad of weather impacts across Colorado, and it succeeded in fulfilling that potential. Heavy rain, burn scar flash flooding/debris flow, hail up to 3 inches in diameter, wind gusts up to 70 mph, and a few tornadoes were the impacts that Mother Nature threw at the state. As far as flooding flooding goes, in La Plata County, a mud flow was reported in the vicinity of County Road 203 and Tripp Gulch, and in Custer County, flash flooding caused washouts on County Road 387. Some of the more severe hail, wind, and tornado reports are as follows:

68 mph wind gust: 11 miles ESE of Thurman (Kit Carson County)
67 mph wind gust: 1 mile E of Kit Carson (Cheyenne County)
57 mph wind gust: 3 miles SW of Leader (Adams County)
3 inch hail: 5 miles E of Flagler (Kit Carson County)
1.75 inch hail: 3 miles NNE of Wellington Lake (Jefferson County)
1.25 inch hail: 7 miles NE of Ponderosa Park (Elbert County)
Tornado: 7 miles S of Byers (Arapahoe County), 2 miles NE of Ponderosa Park (Elbert County), 11 miles SSE of Leader (Adams 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 accumulation ending time is 6AM of the date shown in the bottom right corner. Also shown optionally are fire burn areas since 2012. The home button in the top left corner resets the map to the original zoom.
Note: We have identified a possible underestimation in QPE over the southwest part of the state. We are working to on this issue, and will provide an update as soon as possible.
