heat wave

Extreme heat is scorching much of the eastern United States, and it's not expected to let up anytime soon. Experts at the National Oceanic and Atmospheric Administration's Climate Prediction Center say much of the southern half of the country will be hotter than normal in August, with the worst conditions in Texas, Louisiana and parts of Mississippi and Arkansas.

"We have quite a few records being set," said Deke Arndt, chief of the climate modeling branch of the National Oceanic and Atmospheric Administration's National Climatic Data Center. "This is a very large heat wave."

The agency has placed large swaths of the Midwestern and mid-Atlantic regions, as well as the Ohio Valley, under "excessive heat warnings," which it issues when it expects a heat index of at least 105 degrees Fahrenheit for three hours a day, two days in a row, or a heat index of 115 degrees for any length of time.
