I have a distinct memory of a report on NBC nightly news from some time in the 80s where they said Mount Washington recorded a wind chill of -200. I'd have to think the -107 is more likely but maybe I'll try to find it in the archives somewhere.
I'm afraid if I go snow blow now that band just to the west is going to drop another 6 before morning. Seems like it wants to slowly come east. 30F, light-mod snow
