The All-Time Low Temperature in Each U.S. State

We've examined all the weather records in the NOAA database to determine the all-time lowest temperature recorded in each U.S. state.
There are very few weather stations at high elevation, so the actual lowest temperatures might be quite a bit lower in states with high mountains.
All data displayed in U.S. customary units.
All data displayed in metric units.
Note: All records are current as of August 10, 2021.
