Colorado’s first snowstorm of the season may not go down in the record books, but it still managed to blow past average monthly snow totals for the Front Range and Eastern Plains and provide much-needed moisture for the region. The storm’s long duration was a buffer against some of the worst impacts on metro Denver, said David Barjenbruch, a meteorologist with the National Weather Service’s Boulder office. Denver International Airport and the southeast metro, including Highlands Ranch and parts of Aurora, saw around 20 inches of snow over 96 hours, almost tripling the November average of 7.3 inches.
