/Issued 9:45 AM CST, Wednesday, December 4, 2013/
*13z HRRR model run remains consistent with prior runs in showing another 10-18″ of ADDITIONAL snow through This Evening from Duluth northeast along the North Shore of Lake Superior. Widespread amounts of 4-10″ across the remainder of Northern Minnesota and Northwest Wisconsin.
*Surface analysis from 8 AM Today. L on the map indicates an area of low pressure with the track of this low indicated by the red line. Bitterly cold air plunging south/east over the Western U.S. (behind this storm) mild air flowing north ahead of this storm.
*I increased 3-day snowfall totals along the North Shore of Lake Superior with 20-35″ amounts likely by the time the snow ends by later Tonight. The remainder of the Northland will likely have 3-day totals on average of 8-14″, but there will be pockets of higher amounts in the 14-18″ range.
*Upper Midwest radar loop ending at 9:15 AM CST.
*Winter Storm Warning continues for Duluth and Superior*
*At 9 AM low pressure was more or less over Western Missouri (1002mb) This low will lift north/northeast through Tonight and should track from Southwest to Northern Wisconsin through the Evening.
*Snow which could be heavy at times will be widespread Today in Northeast and East Central Minnesota and in far Northwest Wisconsin, or on the west/northwest side of the surface low. Note: Snowfall rates could reach 1″ an hour in some locations during the next 6-10 hours.
*Enough warm air is expected to move into the Southeast portion of NW Wisconsin to cause a mix of snow, sleet, and freezing rain by This Afternoon. The area at risk for this icy mix of precip looks to be from around Exeland toward the Hurley area, and points southeast from there. Ice accumulations could reach 0.05-0.15″ by late This Afternoon over parts of Iron and Price County, and over Southern Sawyer County.
*Brisk east to northeast winds will also continue Today with wind gusts to 25 to 40 mph near Lake Superior which will cause considerable blowing and drifting snow and possible brief whiteout conditions at times.
*If you must travel Today be sure to slow down and use extreme caution. Allow plenty of time to reach your destination. Have a winter storm survival kit in your vehicle in case you become stranded.
