Winter Storm Expected

Written by on March 2, 2018

A winter storm is expected on Sunday and Monday (March 4-5). Confidence is HIGH that much of the area will see some accumulating snowfall. Confidence is HIGH that much of the area will have strong northwest winds. Confidence is LOW regarding the exact track of the system, and where the heaviest snow will fall.

Main points:
• Snow begins Saturday night over northeastern Wyoming and northwestern South Dakota before spreading eastward across western South Dakota on Sunday.
• Freezing rain may precede the snow across the western South Dakota plains, with rain over south central South Dakota.
• Snow will taper off Monday night across northeastern Wyoming and Tuesday over western South Dakota.
• Strong winds are expected Sunday evening through Monday Night. Windy conditions will continue on the western South Dakota plains through Tuesday.
• Blowing and drifting snow will reduce visibility and affect travel.
• The cold, wet, and windy conditions may be hazardous to young livestock.

A snow depth graphic is available at but it’s looking like north of I-90 in Wyoming will see 4-6″ possible, while south of there may be 2-3″
