These posts contain some discussion of the white stuff, whether it be mountain snow pack or a Front Range snowstorm.
The first real storm of the season is heading towards Colorado, but unfortunately it will track too far north limiting the overall impacts to the Denver Metro area. While the Mountains are poised to receive plenty of snow from this system, the lower elevations will see just a little bit of rain alongside gusty downslope winds. In the wake of the storm, temperatures are expected to drop below freezing Friday night bringing an end to the growing season for many plants. Let’s take a look at the latest timing of the rain and snow and discuss the drastic change in temperatures headed our way!

All is quiet to kick off the week in the Front Range with high pressure in place across the Rockies. Temperatures will start out close to 80 degrees Monday and Tuesday but that won’t last long. All eyes are on a potent autumn storm system moving in from the Pacific Northwest later this week. Model uncertainty is somewhat high in regards to the storm’s track, but consensus currently would indicate a decent chance of rain in the Denver Metro area with snow possible along the Wyoming border and in our nearby Mountains. Things could certainly change as we get closer though. Either way, it will be a colder end to the week with the first freeze of the season possible Friday and/or Saturday mornings.
September 2023 was an overall warm and dry month in Boulder, but technically we did finish with above normal precipitation. Almost all of that came on a single day as a result of a locally heavy thunderstorm. We’re yet to see a real autumn storm in the Front Range and as a result it hasn’t snowed yet outside of the Mountains, which is fairly normal with our average first snowfall not coming until mid October. Here’s a quick and colorful graphical recap of our weather during September and how it relates to climatology.

BOULDERCAST 2023 FIRST SNOW CONTEST ENTRY FORM
*Sorry but this contest is now closed to entries*
A ridge of high pressure will remain in control of Colorado through the extended and even intensifies this weekend keeping us mostly dry and hot. The best chance of rain in the pipeline comes on Friday, but only limited rainfall is expected from storms due to a lack of moisture. Additionally, the remnants of major Hurricane Hilary in the Eastern Pacific will arrive to the USA this weekend but stay well to the west of Colorado unfortunately (boo!). Things dry out further this weekend into early next week as temperatures once again make a run towards triple digits in the Denver Metro area.
