Excessive Heat in Muskogee, Oklahoma

A ridge of high pressure in the middle and upper atmosphere redeveloped over the south central United States during late July. Unseasonably hot afternoon temperatures reaching the mid 90s to near 100 degrees, combined with unseasonably high humidity, resulted in heat index values in the 110 to 115 degree range across much of eastern Oklahoma on the 29th through 31st. At least six people were treated for heat-related issues in Tulsa, three of which were transported to the hospital. This heat wave persisted into early August.
