Looks like mainly a Metro Buffalo event, we've been in the transition zone this year. We should get hit pretty good but the lake is quickly freezing, so not sure how hard we get hit. Here is the map from KBUF. Looks like Philly and WxWatcher are chasing on the tug, we also have 2 posters from there in Redfield and Altmar.

850 temps are all well and good (and those are truly impressive) but people live at the surface.  Are records expected to be set where the people are?   

Even if there are no records those temps and windchills are sick

Dave,   I believe the coldest "maximum" temperature at Chicago O'hare is -11F.  Tomorrow should break that.   Quite a day for metro Chicago with highs around -15F and lows -25F or a bit lower.

I watched the evening news, ABC and NBC.   Showing the maps and talking about the temperatures was very confusing.  Real feel temps, wind chill temps and actual temps.  The maps were all over the place and half the time the anchors and their weather people were too.    I understand the difference but not sure the average person does.   Maybe it doesn't make a difference??

-5F right now. They have 3.5hrs to drop 7F. Gonna be tough to avoid the midnight high.

That 850 mb map that Ginx posted is pretty much record territory for Indiana.  We are at the mercy of RAOBs being taken only twice a day, so stuff can slip through the cracks so to speak (and there are no RAOB locations in IN) but looking at 3-6 hour reanalysis images of past arctic outbreaks... yeah, -37 basically never happens that far south.  

Low level lapse rates are pretty steep when those 850 mb temps occur... so while it's very cold at the surface, maybe not as cold as you would think.  Tomorrow night is a better radiational cooling setup, but there is a lack of snowcover with southward extent in IN.  The overlap of favorable sfc ridge position and deep snowcover is farther northwest... IA/WI/northern IL and maybe northwest IN.  Assuming clouds aren't an issue and winds go calm (or nearly calm), there could be some pretty nutty readings in that zone.
