These maps show the projected increase in average daily July heat index relative to the
present. The largest increases are in the southeastern states, where the models projects
increases of more than 25°F.

A July day in Atlanta that now reaches 105°F would reach 115°F in the Hadley model, and
130°F in the Canadian model.
