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:

Loveland Pass is on the edge of two weather worlds: Low clouds and drizzle will persist across the east slopes of the Front Range and plains today. Above about 11,000 feet and west of the Continental Divide it will be another sunny, mild day. #cowx

Summary:

After Thursday’s record-breaking heat, a much welcome cool down came to the state Friday following an early morning cold-frontal passage, which significantly cooled temperatures and brought broad overcast, gloomy conditions to much of Eastern Colorado. Daily highs for the Front Range, Urban Corridor, and Northeast Plains were in the 50s and 60s, compared to 90s just the day before. In the afternoon through evening, the Southeast Mountains and southern I-25 corridor saw showers and thunderstorms, with up to 0.31 inches reported in Colorado City.

Overnight upslope flow from a shortwave trough dipping in from the north brought long-duration, soaking rainfall overnight to the Front Range, Urban Corridor, and Northeast Plains. From north to south, some impressive rainfall totals from CoCoRaHS for the Urban Corridor include:

• 0.82 in Fort Collins
• 0.90 in Boulder
• 0.94 in Lakewood
• 0.61 in Littleton

Western Colorado saw a bit of a cool-down as well yesterday, though not as significant – highs were in the 80s and low 90s. The west also stayed largely dry with the exception of the very Southwest Slope and San Juan Mountains, where afternoon storms were able to fire up from the moisture associated with the tropical remnants of Kay. Up to 0.44 was reported from CoCoRaHS observer in Durango.

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.

Summary:

Colorado kept up the hot and dry weather yesterday, with record-breaking temperatures reported by the Boulder National Weather Service in Denver, Fort Collins, and Boulder among others. The state continued to see very little precipitation. A few 0.1” -0.12” observations were reported in the Central Mountains and Southwest Slope, but most areas received only a few hundredths of an inch if they saw any rainfall at all.

The state may have continued to see dry weather and record-breaking heat, but the drought monitor showed up improvements from last week. See the weekly drought monitor update below to view the improvements in most of the categories!
