Excessive Heat — Panola, Texas

2023-09-06 to 2023-09-07 · Panola, Texas

Wider weather episode

An upper-level ridge of high pressure expanded across the Southern Plains and extended eastward along the Gulf coast through the first week of September. Meanwhile, a weak surface front shifted southward into the Middle Red River Valley of Southeast Oklahoma, Northeast Texas and Southwest Arkansas, with moisture pooling observed near this front over much of the Four State Region. Strong subsidence observed beneath the upper ridge resulted in compressional warming, with temperatures climbing into the upper 90s to well into the triple digits across East and Northeast Texas. In addition, southerly low-level flow pushed dew points into the lower to middle 70s. Therefore, max heat indices reached or exceeded 110 degrees on September 6th and 7th.
