Oklahoma continues to get scorched by extreme heat and drought.
The entire state is now in extreme drought, and more than 70% of the state is in
severe drought (or worse), up from 50% just a week ago.

According to Gary McManus of the Oklahoma Climatological Survey, July was the
23rd month out of the last 28 to come in warmer than statewide averages.
Bloomberg reports:

More than 64 temperature records were broken in Oklahoma during a scorching
July, and additional ones fell across the state Wednesday on the first day of
August, according to the National Climatic Data Center.

The National Weather Service reported that Guthrie, about 30 miles north of
Oklahoma City, registered 114 degrees to break the statewide record of 113
degrees, set at Meeker in 1896 and tied in Ralston last year.
