Excessive Heat in Muskogee, Oklahoma

A ridge of high pressure in the middle and upper atmosphere redeveloped over the south central United States during mid August. Temperatures reaching the mid 90s to near 100 degrees, combined with unseasonably high humidity, resulted in heat index values in the 110 to 120 degree range across much of eastern Oklahoma from August 13th through 19th. At least sixteen people were treated for heat-related issues in Tulsa, eight of which were transported to the hospital.
