Winter Storm Recap: The first “Rainy Christmas” in Boulder since 1942, but the Foothills got blanketed by wet snow!

Yesterday on Christmas Day, a deluge of rain dumped on the western Denver Metro area during the afternoon and evening, but amazingly not a single snowflake fell across most of the lower elevations as temperatures remained several degrees too warm for frozen precipitation. This led to the first “Rainy Christmas” that most of us have ever experienced. As expected, a white Christmas was enjoyed by those in the higher terrain where temperatures were colder. We recap the holiday raindrops and snowflakes, including a look at just how rare Christmas rain really is and if it will be the new normal in a warming climate.

November 2024 Graphical Weather Review: Modest but widespread drought improvement in eastern Colorado thanks to one of our all-time wettest Novembers

November 2024 was exceptionally moist across most of eastern Colorado, with some locations nabbing their wettest November on record.

While there is certainty still more work to do, the widespread wet weather allowed for modest drought improvement across much of the state. Despite a late and lackluster start to the snow season, Boulder and Denver have both surged above normal season-to-date. Here’s a quick and colorful graphical recap of our weather during November and how it relates to climatology.

October 2024 Graphical Weather Review: Wrapping up the driest May to October period ever recorded in Boulder!

October was yet another exceptionally warm and dry month in the Front Range, with most areas landing more than six degrees above average while receiving very little if any precipitation. The period of May to October only produced 4.64″ of precipitation in Boulder, the driest such stretch in recorded history. It’s no surprise that drought has further expanded across the region. In contrast to our boring weather, space-related activity was booming in October with multiple nights of auroras lighting up Colorado’s skies and a multi-week comet display. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.
