If I were LOT, I don't know if I'd even bother issuing an advisory in most of the cwa. Total amounts may make it into advisory criteria in some areas, but magnitude of road impacts are questionable overall. And for Chicago metro, precip onset doesn't look to be until around the start of rush hour Wednesday morning, so not like there will be ample opportunity for conditions to go to shit prior to the commute.
The best argument for an advisory may be the ridiculous lack of snow so far this winter, lol
