In mid-June 2025, Wyoming experienced an unseasonal winter storm, leading to the temporary closure of the Beartooth Highway. The Wyoming Department of Transportation (WYDOT) worked to clear between 12 and 14 inches of snow, with drifts reaching up to 3 feet, to reopen U.S. Highway 212.
The storm originated from a surge of cold, moist air from the Gulf of Alaska, impacting northwest Wyoming on Saturday and spreading across the state by Sunday. Mountain ranges in western Wyoming received several inches of new snow between Saturday and Monday, with Togwotee Pass reporting 2.5 inches.
The event also brought record-low temperatures to various communities. Casper/Natrona International Airport recorded a low of 32°F, breaking a 1987 record. Riverton, Worland, and Rock Springs also set new record lows. Meteorologist Don Day described the storm as an "everything-but-the-kitchen-sink" event, underscoring the state's unpredictable climate.
The Beartooth Highway reopened on June 23, 2025, and travelers are advised to check road conditions before traveling.
