Weather map drawn by the Weather Bureau's Toledo observer and published in the Toledo Blade in Nov. 1913. Depicts the formation of the w:en:Great Lakes Storm of 1913. Unlike modern weather maps, these showed no warm/cold fronts, since frontal mechanisms were not yet understood, and isobars were located in part by eye and guess.

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 White Hurricane)
