This forecast map from the GFS at about the five thousand foot level indicates that the dew point temperature of plus two to plus four degrees Celsius over a large part of eastern Minnesota suports rain at noon on Thursday. From about Brainerd to Duluth northward the surface temperatures will hoover close to thirty-two degrees.
Here is the latest concensus track for two surface low pressure systems. System one has the potential to dump four to seven inches of snow from Grand Forks to Roseau, including Thief River Falls on Thursday.
The second low tracking towards Kansas City on Thursday could turn north and produce a band of heavy snow close to the Twin Cities to Duluth on Friday into New Year’s Eve.
