Overview

A major winter storm moved through the Northern United States from January 2nd to January 3rd, 2023.  This winter storm brought record snow to some locations, with upwards of 27 inches reported in portions of south central South Dakota, northeast into western Minnesota.

Thundersnow was reported at the peak of the storm early on the morning of the 3rd, producing snow rates as high as 2 to 3 inches per hour within a narrow band from central Nebraska into Southwest Minnesota. 

Warmer air on the southeast side of the system limited snow accumulations in northwest and west central Iowa, but produced rain, freezing rain, and sleet with generally minor impacts. 

This multi-day storm produced record snowfall in many locations, and has pushed the seasonal snowfall totals in city such as Sioux Falls, towards the top of the historical records.
