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.

This Week in Colorado Weather: Autumn Finally Arrives! 🍁🍂🎃
You wanted fall? You got it! After one last summer-like day Monday, a strong trough will bring the risk of rain for a few days with much cooler temperatures to follow. Still no snow tho: https://t.co/6bvFJ8V15T #COwx pic.twitter.com/jpmUeP15lE

It's about time! We hate making snow maps when we're not in "snow zone", but here you go… ❄️
6-12" possible in the high Mountains, heaviest late Wednesday night into Thursday evening. Elsewhere, just a trace to 1" possible high Foothills!

#Boulder's frost of the season is in the bag as we officially hit 30°F this past Friday morning, only a few days later than median during El Niño! Frost is defined here as the minimum temperature being less than or equal to 32°F. #COwx pic.twitter.com/VgqbB5GIj5

🥵🌡️ #Boulder officially tied a 20-year-old record high on Tuesday reaching 85°F! It will be cooler today behind an overnight dry cold front, but still we will be above normal. Not the kind of cold front we want to see this time of year, that's for sure! #COwx #Boulderwx pic.twitter.com/4Wn8TAnUpI

Well… El Niño is finally back and it’s a strong one! Here’s what it means for Colorado this winter ☃️🏔️🌎–> https://t.co/rXHgYBI4es #COwx #Colorado #Denver #Boulder #ElNiño #ENSO #COsnow

🏜️ It's been incredibly dry of late — even by Front Range standards. Just 0.03" of rain has fallen in #Boulder over the last 7 weeks. This is the second driest this stretch has ever been since the 1800s! #COwx pic.twitter.com/uPhlP0X6SX

Not much action is expected during the day Saturday, but things will get cranking quickly around mid-afternoon! Take advantage of the next few hours, if needed, but plan for difficult travel developing late afternoon through Sunday morning! #COWx pic.twitter.com/jtXEnlKwUN

How about a look at Most Likely vs Actual snow totals? Overall this storm came in low for most, but not too bad. This was the biggest dumping of moisture we've had in EIGHT weeks #COwx pic.twitter.com/K9ory4lcxj

Last Halloween in 2022 had a high of 70° and sunny skies in #Boulder. This year we may technically get credit for a "white Halloween" with one inch or more of snow on the ground! 🎃❄️ #COwx pic.twitter.com/RTP9pl0X6v
