An update on this weekend’s system

  • Computer models remain far apart on a storm track for this weekend.
  • Euro model continues to be the furthest east, with little to no impact/snowfall in northeast Minnesota and northwest Wisconsin.
  • GFS model has also shifted quite a bit to the east compared to 24 hours ago, with the GFS model showing a stripe of snow impacting southeast Minnesota through the southern half of Wisconsin, with little if any snow across the Northland this weekend.
  • And then you have a few models which remain much farther west with the storm track resulting in a higher impact snow event across the Northland, those models include the UK and Canadian.
  • So although uncertainty remains high on a storm track for this weekend, the trend at least in the two major computer models (GFS and Euro) is to keep this system south/east of the Northland, with very little snowfall in our local area from Friday through Sunday, December 11-13.

Note: Blue areas on the map below represent where accumulating snow would occur this weekend based on the different storm tracks per UK and Euro models from the 12z model run from Monday morning, December 7, 2020.

8/20 or 40% of GEFS members (12z run) show at least 2″ of snow in Duluth this weekend, this is down from 70% on Sunday. This isn’t a good trend if you like snow.
