Late Week Storm to Impact the Midwest/Great Lakes

While rain falls this morning and afternoon we're already eyeing another significant storm system that could impact the Midwest and Great Lakes by next Thursday and Thursday Night.



European Model Thursday Evening

Even though it's several days out, low pressure looks to develop near the panhandle of Oklahoma and lift north of Springfield Missouri by Wednesday evening and then north of St. Louis, MO to just south of Chicago by Thursday evening.  A swath of heavy snow will likely fall somewhere from Iowa, Illinois, Wisconsin to Michigan by Thurday night.  It's just a matter of where exactly that band will be.   The first image on the left is a snap shot of the European model for Thursday at 6pm.  If this were to hold true precipitation would initially begin as a mixture of rain and snow late Wednesday night into Thursday morning.  As the low passes near Chicago a possible change over to heavier snow would occur from northwest to southeast.

The second image is a snap shot of the American GFS model during the same time period.  It also has a strengthening low developing by Thursday evening but it's shifted a little further northeast.  A shift in either direction would mean a big difference in precipitation type and accumulation.  We'll continue to analyze each model run as they continue to come in this weekend and early next week and provide the latest updates right here as shifts in the track and intensity are to be expected.
