Significant Snows Possible!


A significant winter storm looks to be on track to impact South Dakota starting Friday afternoon and continuing through late Sunday night.  The National Weather Service has placed much of the state under a Winter Storm Watch ahead of the pending storm.  View the winter weather alerts map at our Winter Weather Page.

As of right now, the highest snowfall amounts look to fall from south-central, South Dakota up towards northeast, South Dakota with some locations could easily receive a foot of snow by Sunday evening (purple areas on map below).


Moisture will start to move into southern regions of South Dakota by Friday afternoon and continue to spread northward as the afternoon and evening continues.  Some mixture of rain, freezing rain and snow is expected.

By Saturday, snow is expected for central and southwest, South Dakota with a wintry mixture for east-central, South Dakota and back towards western regions of southeast, South Dakota.  Temperatures look to be warm enough to support rain across the southeast.

By Saturday night, all the precipitation looks to change over to snow.  Areas of blowing snow is possible with strong north to northwest winds.

Snow chances continue into Sunday and even Monday.
