Summary:<\/h3>\n

A surface low over the western Southeast Plains helped pull moisture in on it’s east and north side, while it scoured out moisture to the east on its south side. This increased the chances for heavy rainfall over the Northeast Plains and Palmer Ridge, and decreased chances further south and over the Southeast Mountains. With less upper level support on Thursday, the severe storm and larger hail threat was lessened. Storms began to fire over the Front Range and Palmer Ridge by mid-afternoon, and they increased in intensity at about 104W or around Highway 71. Over the Palmer Ridge, storms produced wind gusts around 60mph and hail up to 1 inch. Outflow<\/span> winds caused 4” diameter tree branches to snap near Byers. QPE<\/span> was measured between a half inch and 3 inches in the cores of the storms. I’m not completely convinced that 3 inch value is real, but it is showing up on the MRMS, AHPS, and MetStorm QPE<\/span> maps. I can’t find any other observations in the area, so it’s hard to confirm. In south, central Logan County, a 1.1 inch CoCoRaHS<\/span> station was the highest observation for the day.<\/p>\n

Another area of heavy rain was over Logan County with a storm report of 2.48 inches. Along with heavy rainfall, this storm produced a 59 mph wind gust and hail up to 1 inch. There may have been some hail contamination with the hail reports directly over the observation, and the hourly rainfall totals don’t look quite right at the gauge itself. QPE<\/span> between 1.5 and 1.75 inches seems more fitting for storm and the duration of rainfall.<\/p>\n

Back to the west over the mountains, 0.35 inches were measured by the Fort Collins mesonet with the scattered<\/span> storms that formed. It was bone dry over the western slope, although clouds that formed near the Divide<\/span> may have caused a sprinkle or two. Flooding was not reported on Thursday.<\/p>\n

\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE<\/span>) 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<\/span> 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.
