FOG BLOG WEATHER LOG: WORST SNOWSTORM SINCE '03 HITS WYOMING , COLORADO AND NEBRASKA:

A widespread, late-season snowstorm laid siege to parts of Colorado, Wyoming, Nebraska and South Dakota on Saturday and Sunday, dumping snow measured in feet in some areas and setting historic snowfall marks in two state capitals. As of 5 a.m. Monday, Cheyenne, Wyo., had received 30.8 inches of snow in the storm, with drifts as high as four feet. The snowfall topped the city’s previous record of 25.2 inches for any two-day period and 25.6 inches for any three-day period, both set in November 1979.

Denver International Airport (DIA), the city’s official weather-observation site, recorded 27.1 inches of wind-driven snow on Saturday and Sunday. This ranks as the largest two-calendar-day snowstorm on record for Denver (though larger two-day totals have fallen in more prolonged storms, such as the mammoth 37.4 inches recorded on December 4 to 5 in 1913 within a five-day marathon that produced 45.7 inches). It’s also the largest three-day total since 2003.
