October 2023 was an overall warm and very dry month in Boulder, but the days leading up to Halloween turned markedly colder with our first snowfall of the season arriving just a tad later than usual, and it was a sizable one for many! Despite the dry last few months, officially drought has not yet returned to the Front Range. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.

It’s been over six months now, but winter weather is finally set to return to the Front Range this weekend as the coldest air of the season shows up alongside several inches of fluffy snow. An interesting weather setup will have a stalled jet streak directly over Colorado Saturday evening seeding a lengthy period of scattered heavy snow bands. Snowfall amounts, while still somewhat uncertain, have trended upward and some of us could see up to a foot of snow this weekend! Read on for our latest thoughts on the storm, including when the heaviest snow will be around, how much accumulation to expect and just how cold it will get. We also reveal the entries to our 2023 First Snowfall Contest since a winner for that will surely be crowned this weekend!
Key Messages:
- The Colorado Buffaloes football game Friday night in Boulder begins at 8PM — there will be nice weather but cold with temperatures in the 30s throughout the game under clear skies
- The first hard freeze of the season is possible but is now looking less likely for the Metro area Friday night as high clouds will move in overnight
- The same clouds will be be around early Saturday morning, possibly impacting the view of the annular solar eclipse
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.

August 2023 ended up warmer and wetter than normal in Boulder — an uncommon pair of outcomes indeed. The summer monsoon failed to produce consistent precipitation across the state throughout the whole month (woefully dry in the middle), but most areas made out alright with drought still thankfully absent from eastern Colorado. The month had 14 90-degree days bringing the total count to 30 days year-to-date. Elsewhere, a DVD-sized hailstone that fell in far eastern Colorado was confirmed to be a new state record. Here’s a quick and colorful graphical recap of our weather during August and how it relates to climatology.
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.
Temperatures and precipitation ended up about as close to normal as possible for July in Boulder. The month began active with numerous severe weather outbreaks, some of which produced landspout tornadoes in parts of Denver. The last few weeks turned up the heat with a total of fifteen 90-degree days during the month. Here’s a quick and colorful graphical recap of our weather during July and how it relates to climatology.
