Alaska sometimes gets wind chills that low, but I don't think it's typical. A quick websearch for Alaskan windchill records didn't turn up anything conclusive but a few results suggesting record-setting chills of -97 F and other claims in that neighborhood. Fun fact: the Antarctican interior sometimes gets cold enough to freeze CO2 (if the CO2 were at 1 atmosphere of partial pressure, which it isn't in air.)
