Summary:<\/h3>\n

General increase in shower coverage during the afternoon hours thanks to a passing shortwave trough<\/span> rounding the ridge. The shortwave<\/span> started the morning over the northwest corner of the state, but without much instability and low-level moisture, cloud cover and virga<\/span> were the main outcome. Throughout the day the shortwave<\/span> traveled to the southeast and arrived to the Front Range and Southeast Mountains by mid-afternoon. Instability was greater over the southern mountains, Raton Ridge and Palmer Divide<\/span>, so coverage of storms was greater over these area. Some weak thunderstorms were also able to form over the southern ridgelines of the San Juan Mountains.<\/p>\n

For the most part, the lack of low-level moisture had the storms producing more gusty winds and dangerous lightning than wetting rainfalls. A CoCoRaHS<\/span> near Arriba measured 0.6 inches with radar estimates up to 1 inch\/hour. A USGS gage recorded just over 0.5 inches outside of Colorado Springs in the Black Forest. Small hail was also reported (0.88 inches) in the storm near Colorado City. 24-hour totals over the SNOTEL ranged from 0.1 – 0.3 inches over the Southeast and San Juan Mountains. Storm activity began to decrease from west to east after sundown. Lastly, a Flash Flood<\/span> Warning<\/span> was issued for the Spring Creek fire, but as of Thursday morning, there was no flooding reported.<\/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 fire burn areas (post 2012), which are updated throughout the season to include new burn areas. The home button in the top left corner resets the map to the original zoom.
