All of the hi-res models have a break in the precip ranging from 1-3 hours during the morning - a break between the initial warm advection shot and the frontal band.   Unclear if drizzle/freezing drizzle would persist during that break.

Freezing drizzle, mist and fog are horrible to deal with. Had it happen once at school and my car door was frozen shut from all the ice build up overnight. Coats everything and accretes very easily. I've been seeing the cutoff of precip too. Judging by soundings, looks like it could be a drizzle with the lower profile still marginally saturated. That will play a role on ice accumulations for areas east of the BR. I think areas like WV Panhandle and HGR will be pretty tough to completely scour out the cold.

The Swiss model has widespread freezing fog in the NW burbs around 9am tomorrow.

Interesting. I don't have access to the Swiss model, but it seems to do an okay job overall. How's it handling the setup so far?

It's free on weather.us.  It's been shifting around a bit like the other short-range models, but I'm keeping an eye on it because from what I can tell it did pretty well a couple of days ago.  Here's its 06z run before the last event.

Here's the map I generated above for tomorrow's event.

Nice. Thanks! About to changeover at work. Will take a look when I get home.
