Overview

A dynamic and complex low pressure moved through much of the Plains on Saturday, March 5 into early Sunday, March 6. Across our forecast area, this system brought everything from thunderstorms and small hail in northwestern IA, rain and freezing rain, sleet and graupel, before transitioning to snow from South Dakota into southwestern MN and northwestern IA through the afternoon and evening. Ice accumulations were generally a tenth of an inch or less.

 

Some areas across south central into southeastern SD reported heavy snow, with isolated reports of over 6 inches. Breezy northwesterly winds gusting up to 45 mph at times created plenty of blowing and drifting snow through the night.
