An upper level ridge of high pressure over the Southern Plains eventually shifted east and became centered over Southwest Arkansas and North Louisiana during the second week of August, resulting in a period of excessive heat as afternoon temperatures climbed into the upper 90s to in excess of 100 degrees from the 11th to the 14th. This ridge, which resulted in sinking air that compressed atop a dry ground, occurred over an area south of a weak stationary front over Southeast Oklahoma and Southwest Arkansas, which only allowed for minimal mixing each afternoon. This resulted in heat indices consistently ranging from 110-114 degrees each day across much of North Louisiana. The approach of a weak surface front, increased cloud, and isolated to scattered showers and thunderstorms during the 14th resulted in slightly cooler temperatures and lower heat indices over the region.
