Excessive Heat — Little River, Arkansas

2023-08-09 to 2023-08-14 · Little River, Arkansas

Wider weather episode

An upper ridge of high pressure strengthened farther into Oklahoma and Texas through mid August. Meanwhile, a weak surface front remained stationary across portions of Eastern Oklahoma and Central Arkansas, with moisture pooling observed near this front across the Four State Region. Strong sinking motion observed beneath this ridge resulted in compressional warming, with temperatures climbing into the upper 90s to lower triple digits across all of Southwest Arkansas. Given the limited mixing of dewpoints observed, oppressive heat was observed with heat indices reaching or exceeding 110 degrees throughout much of mid August.
