A strong upper ridge of high pressure built over the Mid-South from July 24th through July 26th, 2010. Meanwhile, a surface boundary sagged further south into East-Central Arkansas that allowed higher dewpoints to pool along the boundary. The combination of the heat from the ridge and the higher dewpoints produced heat index readings between 105-109 degrees during this period.
