DES MOINES, Iowa (AP) — It looks to be a miserably hot weekend in parts of Iowa and Nebraska this weekend. The National Weather Service has issued a heat advisory for Des Moines and central and northern parts of Nebraska and Iowa.

The service says temperature in the mid to upper 90s, combined with high humidity, will send heat index values into the triple digits in Nebraska on Saturday. The heat advisory will remain in effect for Des Moines and other parts of Iowa through Sunday evening.

The service cautions people in the advisory areas to drink plenty of fluids, stay out of the sun and stay in an air-conditioned room, if possible.
