Jan 31, 2019 at 17:50	comment	added	dplmmr		That looks like the same class of Automated Weather Observing System (AWOS) mentioned by the State Climatologist Office for the -37 °F measurement, and the reports around that time don't have any error codes. So a site like that could conceivably produce an official record low temperature if it passed a more detailed quality control analysis (although in this case I wouldn't be surprised if it doesn't get any special attention since it wouldn't quite make a major new record).
Jan 31, 2019 at 17:41	comment	added	DavePhD		This report of -35 °F wrh.noaa.gov/mesowest/… looks more official. But that doesn't specify what the minimum was, only reports at 20 minute intervals.
Jan 31, 2019 at 17:18	comment	added	dplmmr		My understanding is that the surface observational data assimilated into operational forecast models typically comes from only a set of "official" stations with at least some known maintenance/quality control criteria, not the set of all possible weather stations. That's mainly based on my recollection of what I've learned from the US forecast model community, and based on results from some searching (e.g. the UK community: rmets.onlinelibrary.wiley.com/doi/full/10.1002/qj.2372) it seems to hold up at least to some extent. But that's probably a topic worthy of its own entire question.
