The coldest temperature recorded in every state

On this snowy January day, it was Lucille Hereford, the postmaster and town volunteer weather observer, who recorded the -27-degree temperature, calling it a "terribly cold" morning in a 1988 interview with an Alabama State climatologist.

Per a 2021 news report by WHNT, a local news outlet, the official story comes with a caveat: The temperature was initially erroneously recorded as warmer than the -24 degrees Fahrenheit reported at Russellville the same day. It wasn't until years later that a Birmingham reporter uncovered the truth, and the National Climatic Data Center finally issued a correction in its records.

The Anchorage Daily News reported in 2013 that there have been unofficial measurements of even lower temperatures. On the National Weather Service Alaska website, Phil Schaefer said it hit -84 degrees Fahrenheit in Coldfoot in 1989, and Joe Cochran said the temperature in Hughes dropped to -85 degrees Fahrenheit in the '90s, The Daily News reported.
