This Week in Colorado Weather: October 16, 2023

October 16, 2023 / Andy

The week ahead will usher in persistent unseasonable warmth and sunshine to Front Range Colorado. There’s a better chance of setting record high temperatures this week than there will be to see any kind of precipitation. We are watching a couple of cold fronts, but they will be the dry variety with temperatures not even dropping below normal on their backside. Upper-level ridging will continue to push in from the West Coast for the weekend keeping things pleasant and dry through at least Sunday for our area. As you might imagine, there’s no chance of snow or additional sub-freezing temperatures in the pipeline.

Forecast Update: The first significant storm of the season for Colorado is here, but unfortunately it’s going too far north

October 11, 2023 / Ben Castellani

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!

This Week in Colorado Weather: October 9, 2023

October 9, 2023 / Andy

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 Graphical Weather Review: A quiet transition from summer to autumn, except for one day of torrential rain

October 6, 2023 / BoulderCAST Team

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.
