Blizzard in Fergus County Below 4500ft, Montana

ASOS KLWT Lewistown Airport reported blizzard conditions with winds gusting 30 to 40 mph between 3:22pm to 6:22pm MST. Montana Department of Transportation reported severe driving conditions along MT Highway 200 through the Lewistown Divide, and on US 191/MT Highway 236 from Lewistown through Winifred. A COOP observer in Grass Ranger reported a 24 hour snow total of 22 inches, with a storm total of 27 inches. Another snow report 2 SE Lewistown reported 22 inches storm total 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.
