Heat in Caldwell, Louisiana

Strong heating developed over portions of North Louisiana during the afternoon of August 13th, ahead of a weak upper level disturbance that lingered across portions of extreme Northeast Texas, Southeast Oklahoma, and Southwest Arkansas. As this weak disturbance began to weaken on the 14th-15th, upper level ridging began to amplify east across the region into the Lower Mississippi Valley, resulting in afternoon temperatures climbing into the mid 90s to near 100 degrees each day through the morning of the 19th, before the heat wave intensified further. When combined with the humidity, heat indices ranged from 105-110 degrees.
