Excessive Heat — Bienville, Louisiana

2024-07-01 to 2024-07-05 · Bienville, Louisiana

Wider weather episode

An upper ridge of high pressure built in across the Southern Plains during the first several days of July, before eventually sliding off to the east into the Mid-South and Lower Mississippi Valley. Meanwhile, a stationary front lingered from Southeast Oklahoma into extreme Southwest Arkansas and portions of North Louisiana, which aided in compressional heating and low level moisture pooling, with temperatures climbing into the upper 90s to in excess of 100 degrees. The moisture pooling resulted in minimal mixing of dewpoints, with attendant heat indices ranging from 110-115 degrees each afternoon on July 1st through the 4th. However, slightly cooler and drier air were able to mix into the area on the 5th, resulting in slightly lower heat indices.
