The National Weather Service says another powerful winter storm is bearing down on Minnesota. The latest forecasting models predict the region will begin seeing an icy mix of precipitation Wednesday night. The rain, freezing rain, sleet, and snow is expected to change over to all snow Thursday night and some areas could see a foot of accumulation by the time the storm ends on Friday. A winter storm watch has been issued for southwest, south-central and eastern Minnesota from 1 p.m. Thursday through 4 p.m on Friday. At this point, Rochester is not included in the watch area, but forecasters currently have the Rochester area on the southern edge of the band of heavy snow.
