Snowstorm potential grows.

The latest 12z run of the GFS has shown that as much 6-8 inches is possible over Northwest Ohio and some parts of Northeast Indiana.  This is a large upward in the original snowfall amounts that the GFS was forecasting last night, up from one inch around here.  Right now, the heaviest snow according to this model will fall right along the U.S. 24 corridor, extending back to about Fort Wayne, Indiana.  IF the next couple of runs from the GFS show this much snow or more over the same areas, I would have to say our snowstorm potential grows.  Then again, all of the other models are all over the place with this storm.  The NAM has heaviest snow totals from North Central Indiana through southern Michigan with only about an inch or two for around here.  The 00z run of the GFS was only showing a trace of snow around here.  In reality, I believe this event will be almost exactly like what happened last week.  One thing that cause this storm to be a bit different is the fact that this storm will be moving from the Southern Plains, drawing in arctic air on its north side, instead of Pacific air.  This means that snow potential could be much more than last week.  If the cold air is drawn farther east with this storm, I expect that the storm system will shift to the southeast, making for an even better snowstorm for this area.  If the NAM and ECMWF verify, we would likely get around an inch of rain Monday, along with rain changing to short period of heavy snow Monday Night, and around an inch or two of accumulation, while areas just to the north and west will receive abundant amounts of snow, possibly over a foot in some areas.  I will keep you updated as more data comes in.
