Wider weather episode

Persistent and deep cyclonic flow bringing unseasonably cold weather overtop unusually warm lake surface temperatures continued to result in record-breaking lake effect snow through the remainder of the Thanksgiving weekend into December 1-2. This brought periods of whiteout conditions and hazardous travel conditions as snow bands shifted back and forth over the region. Snow under these most intense bands quickly accumulated to the tune of 1-3 inches per hour, even on main thoroughfares including I-75...resulting in numerous accidents. Widespread 4-day snowfall totals of 2-4 feet in NW/WNW flow snowband areas of NW Lower and eastern Upper Michigan. Highest reported storm total snowfall from trained snowfall observers was 46.7 inches 6 miles SSW of Gaylord, MI, ending 1300EST December 2.
