Summary:<\/h3>\n

Some showers from weak storms over the Central, Southeast, and San Juan Mountains produced generally light rain totals for higher elevation locations, but finally the western San Juan Mountains got some rainfall. An isolated<\/span> area of high rain totals over the last 24 hours were recorded in La Plata County, where 1.12 and 0.76 inches of rain were reported by CoCoRaHS<\/span> observers in Hermosa and Trimble, respectively. A USGS rain gauge just north near Electra Lake picked up 0.38 inches and another station just southwest of town picked up 0.41 inches. Composite radar images indicate two rounds of storms moved over this area between 2PM and 5PM. Due to the limited low-level radar observations in the area and the small, isolated<\/span> storm core, today’s MetStorm Live QPE<\/span> map does not pick up on this rainfall. No flooding reports were submitted from this rainfall as of this morning. The high rain totals were likely possible due to a pocket of increased dew points<\/span> (low 40Fs) that banked itself against the southern edge of the San Juan Mountains, as visible from MesoWest observations and mesoscale analysis. This extra low-level moisture likely allowed increased instability and heavier rain rates. Farther east in Archuleta County, up to 0.22 inches of rain fell according to CoCoRaHS<\/span> rain gauges. Lower accumulations were observed elsewhere.<\/p>\n

Temperatures topped out at 98F in Denver yesterday, which beat the previous record of 97F from 2013. Grand Junction hit 97F, which was 3F from their daily record. Temperatures are likely a few degrees cooler than they normally would be with the thick smoke in the area. Near-record heat is expected to continue today with the very strong High pressure system.<\/p>\n

Wildfire Update:<\/strong>
\nPine Gulch – north of Grand Junction: 87,209 acres; 7% contained
\nGrizzly Creek – Glenwood Canyon: 25,007 acres; 0% contained (no change)
\nCameron Peak – Medicine Bow Mountains: 12,323 acres; 0% contained
\nWilliams Fork – Arapaho National Forest: 6,627 acres; 0% 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.
