SPM 09-11-2022: Cool and Gloomy East, Milder and Pleasant West of the Divide

Issue Date: Sunday, September 11th, 2022
Issue Time: 10:45 AM MDT

Summary:

Saturday saw a continuation of fall-like weather, with cool temperatures and gloomy conditions east of the Divide from the Front Range out into the Plains. In fact, many locations saw their coolest high temperatures since May or early June, with highs struggling to reach 60. Overcast and light rain lingered throughout much of the day, with 0.20-0.40” observed from the Front Range southward along the Urban Corridor and southern I-25 corridor. The heaviest rain appears to have accumulated in the vicinity of Colorado Springs, where a CoCoRaHS observer measured 0.60” near Falcon Estates. For the Plains, amounts were generally 0.10” or less.

West of the Divide was a much different story, with sunshine and milder temperatures making for a more pleasant September Saturday. Check out this webcam shot from Loveland Pass capturing the east/west difference in weather across the state:

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. The home button in the top left corner resets the map to the original zoom.
