The strong storm system is still on track to bring heavy snow and strong winds to the area. In fact, it now appears that the heavy snow will extend eastward onto the plains of western South Dakota.
Rain will move into the area Thursday. The rain will transition to snow over northeastern Wyoming and the Black Hills Thursday night and then change to snow over the South Dakota plains on Friday. Small deviations in temperature or track of the storm will make a big difference in how much snow accumulates. This is the updated snowfall amount expected Thursday night through Friday night. The amounts will probably change some as we get closer to Friday.
Strong northwest winds of 25-40 mph with gusts to 55 mph are expected across western South Dakota. This will cause poor travel conditions. Since many trees still have leaves, the combination of wind and snow may result in downed tree limbs and possible power outages.
