SPM 09-09-2022: Record-Breaking Heat, Showers and Virga

Issue Date: Friday, September 9th, 2022
Issue Time: 11:00 AM MDT

Summary:

Record-breaking warmth continued across the state on Thursday, with locations such as Denver reaching 99° and smashing the previous record high by 5 degrees. This is quite the juxtaposition with two years ago, when Denver broke its daily snowfall record and Boulder recorded 5.6” of the white stuff!

In terms of precipitation, high elevations from the Northern Mountains southward through the Central Mountains and San Juans towards Durango saw light amounts of rainfall. Most locations that saw rain observed 0.25” at most, with stations generally reporting T-0.10”. Noteworthy totals include 0.33” on the Southwest Slope southwest of Durango and 0.27” near Virginia Dale in the Northern Mountains. Showers attempted to move eastward into the foothills and plains, especially along and northwest of I-76, but dry low-level air meant many locations saw only virga.

The heat and dry conditions of late also led to fire concerns, as a wildland fire was sparked north of Fort Collins yesterday. The Larimer County Sheriff’s Office ordered mandatory evacuations for some residents.

No flooding was reported yesterday. For precipitation estimates in our area, check out the map below. Remember, if you observe flooding in your area, you can use the “Report a Flood” page to make a flood report when you can safely do so.

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.
