Summary:<\/h3>\n

Storms stuck to the southern mountains yesterday, producing up to 0.31 inches of rainfall near Cortez (Southwest Slope) according to rain gauges. A similar total of 0.29 inches was recorded near the CO\/NM border southeast of Durango. Radar indicates storms fired over the San Juan Mountains and moved south over these areas over an hour or two during the early afternoon. These rain totals match well with the expected rain rates for the area (0.3 in\/hr) in yesterday’s Flood Threat Bulletin. Further east, along the western edge of the Southeast Mountains, rain totals up to 0.1 inches were reported by CoCoRaHS<\/span> observers.<\/p>\n

Storms were unable to break the cap<\/span> over the eastern border yesterday, even though the low pressure system set up a convergence boundary over Kit Carson County. It is possible the thick smoke over eastern Colorado yesterday may have reinforced this cap<\/span> with mid-level heating from absorption of sunlight by dark smoke particles, potentially suppressing storms over the eastern border.<\/p>\n

Temperatures soared again across the state, as Denver reached 97F (1F shy of tying the record), Grand Junction reached 98F (beat old record by 1F), and Pueblo reached 103F (beat old record by 3F). These hot temperatures are surprising considering the amount of smoke that lingered over the state yesterday, but the drier air and drought conditions likely are exacerbating the heat.<\/p>\n

Wildfires continued to burn across Colorado yesterday (see updated info below). These CO fires along with fires across the US West are generating large amounts of smoke, which is blanketing much of the US West and causing unhealthy air quality. Check out this interactive map from AirNow that shows smoke plumes and air quality across the US:<\/p>\n

Wildfire Update:<\/strong>
\nPine Gulch – north of Grand Junction: 129,715 acres; 19% contained (2nd largest CO wildfire, grew ~ 3,000 acres)
\nGrizzly Creek – Glenwood Canyon: 30,362 acres; 30% contained (increase in containment)
\nCameron Peak – Medicine Bow Mountains: 18,287 acres; 0% contained (grew ~ 1,000 acres)
\nWilliams Fork – Arapaho National Forest: 10,813 acres; 3% contained<\/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.
