From heat to snow: Rocky Mountains see 60-degree plunge
Associated PressSALT LAKE CITY — Summer came to an abrupt halt in parts of the Rocky Mountains on Tuesday as temperatures reaching into the 90s plunged about 60 degrees in less than 24 hours, with a powerful surge of cold air from Canada unleashing snow and damaging winds in several states. The roller coaster weather ripped up trees by their roots, piled up snow that shut down parts of the scenic road through Glacier National Park and knocked out power to tens of thousands. However, Denver’s temperature drop, from 93 on Monday to 32 on Tuesday, is “much earlier than we usually get this,” state climatologist Russ Schumacher said. Warm weather in Montana over the weekend also fueled the rapid growth of a wildfire near the university town of Bozeman, forcing people to evacuate their homes and trapping three firefighters who had to deploy their fire shelters — a last-ditch effort to protect themselves — as the blaze burned over them, the Department of Natural Resources and Conservation said.
