How about the weather of Chicago?

The climate of Chicago is typical of the Midwestern United States, but with distinctive characteristics associated with its position where the Great Plains meet Lake Michigan. Sudden changes of weather, large daily temperature ranges, and unpredictable precipitation patterns are all staples of Chicago weather. Chicago has four clearly defined seasons, although in certain years some seasons may linger into months they do not traditionally occupy, or arrive exceptionally early, preempting the current season. For example, in Chicago it has snowed in September (1942), been 90°F (33°C) in March (1982), and had a day where the high and low temperatures differed by more than 65°F (31°C) (February 8, 1900).
