MODELS:

CMC----
The CMC indicates a strike on Chicago and Milwaukee. It shows the same set-up as this weekend's storm in the Lower GL, except this time, the models show it veering slightly into Chicago and not out as much towards the Quad Cities, Iowa.
Thickness remains fine, and Relative Humidity centered in Western Illinois again. However, it is still affecting most of the area around the GL.

NOGAPS----
The NOGAPS shows the clipper-like system completely missing the Quad Cities, Chicago and barreling into the Upper Great Lakes as a weak system but stronger by the lakes.
Relative Humidity and Thickness fine for the Upper GL.

GFS----
The GFS shows Madison, Milwaukee, and all of Wisconsin facing the storm head on while clipping North Illinois. However, RH (Relative Humidity) will be conductive for the entire East Illinois area. Thickness will be fine.
