Blizzard in Southern High Plains, Montana

Blizzard conditions with winds gusting 30 to 50 mph from 9:30am to 3:45pm MST. Severe driving conditions reported by Montana Department of Transportation and webcam images confirmed the blizzard conditions. Highway 287 between Augusta and Choteau also did close down. A COOP observer 4 SSE Bynum measured 15 inches of snow.

A complex, multi-day weather system moved across the region bringing rounds of wind, snow, and when combined, blizzard conditions. Strong winds aloft brought a round of high winds to the region beginning late on the 11th through the 12th. A low pressure system with a cold front pushed south through the 12th, ending the high wind threat, but bringing a heavy snow threat to the mountains and lower elevations of North-Central MT. The front then stalled, continuing periods of heavy snow through the 14th when gusty winds developed across the I-15 and MT Highway 200 corridor which led to blizzard conditions.
