The 2010 winter season is off to a slow start in terms of snowfall at the NWS office in Negaunee Township in Marquette county. So far, through December 3rd, the total snowfall for the season has only been 8.8 inches. This is the 2nd least amount of snow to start the winter season through this date on record. The previous lowest snow total through this date was just last year, with only 7.1 inches of snow through December 3rd, 2009. Another year with low snowfall during this time frame was in 1962 when when only 9.5 inches of snow occurred. To put this in perspective, the normal snowfall through this date is 32 inches while the highest snow total observed through December 3rd is 69.8 inches in 1989.
Snowfall totals have been higher in the lake effect snowbelts across the Keweenaw peninusla and also east of Marquette - in Munising and Grand Marais. Minimal snowfall has also occurred in the southern U.P as the storm systems that have moved through the area have brought mainly rain to those areas. For example, through November 30th the total snowfall at the Iron Mountain/Kingsford wastewater treatment plant in Dickinson county was only 2.5 inches.
Northerly winds and cold air will result in increasing lake effect snows along much of Lake Superior into the middle of the upcoming workweek. There are also indications that widespread accumulating snow may occur over all of Upper Michigan by late in the week as a low pressure system moves across the Upper Great Lakes region.
