Can someone explain how the snow in Illinois is LES (or at least lake-enhanced) with a W/NW flow?

It's odd given the SFC and flow aloft is out of the WNW/NW, but there have clearly been LE elements affecting Cook Co (From about Chicago on south), as well as Lake Co (IN).

perhaps left over seeders from when the flow was more NNE...then as the vort gathered steam...it enhanced things

 

It appears to be old-fashioned deformation snow to me, with lift squarely in the DGZ (ahead of the main trough axis). Somewhat similar to 12/26/09...

 

Any LE connection seems like a stretch at best.

Interesting stuff.  Semi-persistent area of returns there on the southern part of the lake but doesn't really make sense for there to be lake enhanced precip in that location.  Whatever it is, the models seemed to sniff it out.

 

Besides that, the radar returns would be moving in a more south/westerly direction if it were truly LES or lake-enhanced...

That fine band that Chicago Storm outlined in his post above does look like a lake signature though.  It's a little hard to spot at first since it's mixed in with all the other stuff.
