Friday, November 7th: The East Coast high hasn't moved much, but a new low is shown centered over Minnesota/Wisconsin. This was probably a misrepresentation of an upper-level trough, which meteorologists had no knowledge of in 1913. Unknown to the Weather Bureau, a cold front is sweeping across Lake Superior. Behind it are gale-force northwest winds, and ahead of it are southwesterly gales. The Weather Bureau posted storm warnings at 10:00am Friday. (excerpt from
