Two issues though...
For one, widespread warning criteria snowfall amounts did not occur in Lake or Northern Cook counties. Those type of amounts did occur in Northern Ogle, Winnebago, Boone and McHenry counties though. However, that sort of outcome for much of that corridor had very little in the way of support going into the event. As we all know, higher corridors often do occur, as do 'screw zone' corridors.
As much as I tend to hate on the NWS at times (More-so the SPC), their headlines were perfectly fine in the LOT CWA.
