U.S. weather 2050

Winters and summers will be warmer in every U.S. city by 2050. By 2050, the weather in many cities will be similar to southern cities today. Midwestern cities like Chicago, Cleveland, and Detroit will see some of the most dramatic shifts in winter lows — from the low 20s up about 5.5°F to the high 20s. Bozeman, Montana; St. Paul, Minnesota; and Chicago will all see their average summer high shift up by nearly 6°F — a much hotter overall summer. And America’s biggest cities, with the exception of San Diego, will all see both their summer and winter temperatures shift by more than 3°F on average.
