Hail — Stillwater, Montana

2021-06-10 · near Park City, Stillwater, Montana

Wider weather episode

Severe thunderstorms began across the western half of the Billings Forecast Area during the afternoon of the 10th. A few of these thunderstorms continued into the early evening hours. An inverted trough and strong jet stream moved over the area during this time. In addition, a strong cold front moved across the entire forecast area during the late afternoon hours through the late evening hours. All of these factors led to a few severe thunderstorms producing large hail and damaging winds. The largest hail reported was 2.5 in diameter with the strongest thunderstorm winds being 75 mph.

A different scenario developed behind the front across the Beartooth/Absaroka and Red Lodge Foothills. Very strong winds aloft mixed down to the surface as 50 to 75 mph winds continued for several hours behind the front. These winds resulted in additional damage. Locally higher winds estimated at 80 mph occurred just above and to the south of the city of Red Lodge.
