The first accumulating snowfall of the season occurred over portions of South Dakota and Minnesota last evening through early Thursday morning, October 24-25th. A majority of the snow fell along and south of line from Pierre to Watertown to Ortonville. Snowfall amounts were generally light - ranging from a trace to as much as 3-4" in isolated areas. Due to the brief duration and relatively low intensity of the snow, accumulations were generally confined to grassy areas - with roadways remaining primarily wet.

A few images of the snowfall from area webcams are provided below.
