Did you know?

The value of 118°F is confirmed as a valid observation, but the station sits on a bluff above the river and the observation is characteristic more of the local microclimate than the area climate. If this value is in doubt, the next highest value is 117°F on July 25, 1936 at both Logan and Atlantic.

Minimum (Coldest) Temperature Recorded: -47°F
