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 Canadian model projects increases of more than 25°F.
For example, a July day in Atlanta that now reaches a heat index of 105°F would reach 115°F in the Hadley model, and 130°F in the Canadian model.
