A heat wave is expanding from the Plains and Midwest and will linger in the East through this weekend, bringing many cities their hottest temperatures so far this summer and creating dangerous heat indices.
The National Weather Service has issued excessive heat warnings, watches and heat advisories in the Plains, Midwest and much of the East to warn residents of the dangerously hot conditions over the next few days.
Excessive heat warnings are issued when afternoon heat indices are expected to be dangerous, if not deadly, for those with prolonged exposure to the heat.
