Friday afternoon will be oppressively hot and humid. Daytime temps will reach the middle and upper 90s. Heat indices make it between 100 and 110°F. As always in situations like this, please make sure children and pets stay away from empty vehicles, check on neighbors and take advantage of cooling centers in and around the city of Detroit.
