Front Range Snowfall Totals: December 9-10, 2024

A short-lived period of light to moderate snowfall accompanied the passage of a quick-moving shortwave disturbance Monday evening, mostly impacting the southern and western Metro area. We briefly review the snowfall totals across the region.

now ended almost as quickly as it began Monday evening in the Metro area. The radar animation below shows a roughly eight-hour period ending around 11PM Monday night. Bands of light to moderate snow formed Monday evening and drifted off to the southwest following a surge of upslope flow from the north-northeast direction. Basically only the southwestern half of the Metro area received any snowflakes, with places northeast almost completely missing out. Notice how the snow lingered longest right near the Foothills southwest of Denver — this was expected all along though some locations here had booming totals as a result of the snow stubbornly sticking around for so long.

Our snowfall forecast map issued Monday morning is shown below with storm totals overlaid. Green values indicate our forecast verified, Yellow values mean the observed total was just outside our forecast, while Red was a busted forecast (more than 1″ off). Booming snowfall totals were observed across the southwest Metro area where the snow lingered longest, with generally 1-4″ in these locations. Roads became slick and snow covered at times creating tricky travel late Monday evening. Elsewhere, most of us saw 1.5″ or less.
