UPDATE: An earlier version of this story said that Monday’s snowfall couldn’t break the record for the earliest snowfall in Casper and Cheyenne. Since both cities set the record on the date Sept. 8 in years past, Monday’s storm could break the record if accumulation is attributed to Sept. 7.
CASPER, Wyo. – Monday’s snowfall could break records in Cheyenne or Casper if the snowfall leaves measurable accumulation recorded on Sept. 7.
Wyoming’s two largest cities both recorded their earliest measurable snowfalls on Sept. 8, according to the National Weather Service.
Casper’s earliest measurable snowfall occurred in 1962; Cheyenne’s in 1929.
“Both Casper and Cheyenne, Wyoming, had their earliest measurable snowfalls – at least 0.1 inch – on September 8 in 1962 and 1929, respectively,” the NWS said Monday. “Cheyenne’s record earliest one-inch-plus snowfall set while William McKinley was President – September 10, 1898 – is likely to be shattered.”
The Casper Star-Tribune reported in 2013 that the earliest snowstorm in “populated areas” in Wyoming occurred on Sept. 6, 1929 in Riverton when the town saw three inches.
The NWS says that “snow is considered average in September along the Front Range from eastern Wyoming into eastern Colorado.”
“However, this could still be one of the record earliest measurable snowfalls in these Front Range cities,” the NWS said of Monday’s storm.
