OKLAHOMA CITY (AP) _ Oklahomans struggled through another day of triple-digit heat Thursday, but the National Weather Service said relief was on the way.

Temperatures topped 100 degrees in a number of Oklahoma cities, including 109 in Hobart, 104 in Enid, 107 in Guthrie and Altus, and 101 in Tulsa.

A front was expected to move into the state Friday, lowering temperatures into the 80s and 90s, said Cheryl Sharpe, a National Weather Service meteorologist.
