SPM 06-11-2019: Return of Warm Temperatures with Light Precipitation in the Southeast Mountains

Issue Date: Tuesday, June 11th, 2019
Issue Time: 10:30 AM MDT


Warm temperatures returned across the state yesterday after well below average high temperatures on Sunday. Moisture and cloud cover increased throughout the morning and into the afternoon over southern Colorado, as a high-pressure system centered over southern New Mexico advected warm, moist air from the Gulf of Mexico into the region. Dewpoints in the low 40’s provided moisture for light precipitation over the Southeast Mountains, with measurements primarily between 0.1 and 0.25 inches. CoCoRaHS in the area recorded between 0.15 and 0.3 inches. Isolated, light showers were also radar reported over the southern San Juan Mountains, southern Front Range, and the Urban Corridor between Colorado Springs and Castle Rock. Totals remained low in these areas, with precipitation measurements between 0.01 and 0.1 inches.

Snowmelt continued throughout much of the state yesterday, with maximum temperatures reaching into the 80°F’s over the high country. Overnight lows remained mostly above freezing, inhibiting the snowpack from refreezing overnight. Flood Warnings remain in effect for parts of western Conejos, western Rio Grande, Mineral, and southern Saguache counties. Gauges along the Rio Grande west of Del Norte and in Alamosa remain in Action stage, with waters expected to rise as a result of rain and snowmelt within the area. Minor flooding will be confined to stream banks and low laying areas. Waters within the upper Arkansas River have steadily increased, with Minor flooding and a Flood Warning for issued for Avondale. Areal Flood Advisories have been issued for the following: Los Pinos River near Bayfield, Eagle River at Red Cliff, San Juan River at Pagosa Springs, Green River near Jensen, Duchesne River near Randlett, Gunnison River above Grand Junction, Colorado River near CO-UT state line, Mancos River near Mancos, La Plata River at Hesperus, Animas River at Durango, and Williams Creek upstream from Lower Cristobal. For the latest warnings and advisories, see today’s FTB post as well as NWS Grand Junction and Pueblo.

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 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.
