Overview
A strong spring snowstorm brought blizzard conditions to Montana and North Dakota, as well as far northwestern South Dakota, on April 12-13, 2022. There was a very tight gradient of snowfall amounts, with around a foot of snow across the ND/SD border, to only 1 to 2 inches near Faith and Belle Fourche, and little to no snow accumulations farther south. What we didn't have in snow, however, we made up for in wind, with yet another multi-day high wind event across much of the area. Wind gusts were 60 to 70 mph. Snow finally ended on the 13th, but strong winds continued into the 14th.
