WRF----
The WRF says that the storm will come in just a tad weaker, but still stick around the Chicago/Milwaukee area for a while, still enough to produce very nice accumulations.

GFS----
The GFS reports the same thing as the WRF. Very very similar.

UKMET----
The UKMET puts some more strength and organization into the storm.

CMC----
The CMC shows the storm entering the Illinois area a bit south from Rockford, but still putting in some good snow totals.

WRF vs. AVN----
The AVN shows the storm coming in quicker than the WRF. But they both show the storm putting out good totals.

12-ensemble run----
12 out of 12 ensembles show precipitation occurring from the clipper.
11 of the ensembles show snow occurring.
1 of the ensembles show rain or ice occurring.

Conclusion- Snow will occur, with probably 5 or 6 inches.
