December 14-17 Snow Event (Upper Midwest Affected)
A low pressure system will move northward from the South Central US into the Upper Midwest while intensifying. This system will be drawing in warm air and moisture from the East as well as colder air from the North. It appears that enough cold air should wrap around the western edge of the system so that there will be snow in Minnesota, Iowa, and possibly into the Dakotas. The big question is how much. The trustworthy ECMWF model is predicting upwards of 4 inches widespread across the affected area, while the GFS indicates that the warm air may overpower the cold air wrapping into the western edge of the storm system. It is apparent that the level of cold air and warm air will be the determining factors of this storm, as well as track; the GFS has been shifting southward in the last few cycles, which may affect the amount of snow and rain, as well as placement of the snow and rainfall.
