On the NWS Facebook page, there are, unsurprisingly. claims of 110 and 120ºF one day temperature ranges. Considering that the US record is evidently 103 degrees at Loma Montana, that would be something. My response is: what day? My guess is that people are either telescoping changes that occurred over a few days or a simply exaggerating, which, believe or not, does happen with weather.
So what is the Alaska record for one day temperature change? That's a good question. I'm sure it's over 70 degrees, and will update when I find some examples. If you know of any documented 70+ degrees ranges in one day, let us know.
