The heat will be widespread into next week. On Friday, Denver could reach 100F (38C), according to the weather service. Chicago temperatures could reach 96 degrees (36C) on Sunday. On Tuesday, Washington, D.C., could see a high of 99F (37C) and New York Central Park could reach 96F (36C).

On Sunday, Iowa, Wisconsin, Missouri and Illinois also see a category 4 rating. ...
