Denver is taking this whole “Labor Day means the end of summer” thing seriously.
Just three days after hitting a record 101 degrees on Saturday, Denver was covered in a dusting of snow Tuesday, marking a swing of 60 degrees in under 72 hours, NBC News reports.
Nearly six million people will be under winter weather advisories in the northern and central Rockies Tuesday as a strong dip in the jet stream rushed a torrent of cold air into the region from Canada.
Snow fell in Idaho, Utah, and Wyoming yesterday, with 15 inches falling in western South Dakota.
The 60 degree temperature swing may sound extreme, but it doesn’t come close to a record. On January 15, 1972 in Loma, Montana, temperatures jumped from -52 degrees to 49 degrees, a swing of 103 degrees.
