CASPER, Wyo. — The next round of winter weather will impact the western Wyoming mountains and Natrona County Monday night and throughout Tuesday, said the National Weather Service (NWS) in Riverton.
Snowfall amounts of 2 to 4 inches are possible in Natrona and southeast Fremont counties, “with locally higher amounts possible in heavier bands of snow,” the NWS said.
The weather system should start impacting the western part of the state on Monday afternoon and evening. Below 8,000 feet, the precipitation is likely to be rain and transition to snow in the evening and nighttime hours.
The Teton and Gros Ventre Ranges could get 6 to 8 inches of snowfall, with 2 to 4 inches in Yellowstone. 4 to 6 inches are possible in the Owl Creek and Bridger Mountains, with around 6 to 10 inches or more possible in the Bighorns.
Accumulations will be minimal “due to the marginally cold-enough temps and warm ground temperatures thanks to several days in the 50s and 60s ahead of the event,” the NWS said. “By Tuesday morning, precipitation will be widespread across the region and quickly end from west to east Tuesday night.”
