Hmm.. it may not be a bug. I noticed that the location of the Texas Rangers is 'Texas', not 'Arlington, Texas'. It's possible that the game didn't know what weather to apply to Arlington Stadium.

I did another experiment tracking the Giants move from New York to San Francisco between 1957 and 1958. The new city and stadium name is correct but the weather for the stadium was still New York. I clicked on the 're-import weather database' button and Seals Stadium was updated with the new San Fransicso weather. A very balmy 63 degrees in June.

I think the game needs to automatically run 're-import weather database' after a team moves. Unfortunately, this doesn't help teams like the Texas Rangers or California Angels where the city isn't specified in the Lahman database.
