Overview
A Winter Storm that transitioned to a Blizzard (for portions of the area) brought a swatch of 6-12 inches of snow, mainly along the Highway 2 corridor, from 6 pm on 12/4/2021 to 6 am on 12/6/2021. Isolated areas west of Bemidji saw the highest amounts, near 14 inches. The snow was associated with strong frontogenesis and warm air advection. This band of heavier snowfall amounts was tricky to pinpoint, as the frontogenesis axis was finite and it shifted with multiple ensemble runs. The system started out with lower wind gusts (near 30 mph at times), but these later grew to 50 to 55 mph as the surface low passed through the area. The stronger wind gusts caused whiteout conditions within the Red River Valley Sunday night, which resulted in the closure of Interstate 29. Snow began to decrease along with wind gusts early Monday morning.
Snow
Snow totals from 6 pm, Saturday, December 4, 2021 to 6 am, Monday, December 6, 2021. Note that these totals are preliminary and may not be exact in all areas. Snow measurement is extremely difficult during high wind events.
