Issue Date: Monday, September 12th, 2022
Issue Time: 10:30 AM MDT

Summary:

Sunshine and warmer temperatures greeted the state yesterday, although early Sunday morning saw some of the coldest temperatures of the early fall with several mountain locations experiencing their first freeze. Dense fog was prevalent in the morning across the eastern half of the state before mixing out by late morning, while the western half of the state experienced smokey/hazy conditions throughout the day from western wildfires.

The majority of Colorado was precipitation-free, save for the southern San Juan Mountains where rainfall amounts up to 0.50” were observed. Notable rain gauge observations include 0.44” and 0.39” at automated stations east of Cortez and southeast of Durango, respectively. 0.75” hail was also reported near Vallecito.

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 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.
