Fire Weather Planning Forecast for Southwest Arkansas...
Northwest Louisiana...East Texas...and Extreme Southeast Oklahoma
National Weather Service Shreveport LA
145 AM CDT Tue Aug 18 2026
.DISCUSSION...
This intense heat shows no hope of breaking anytime soon as
triple digit heat is here to stay. Even worse is the very low
afternoon humidity with values ranging from near 22 to 36
percent...at least for today through Wednesday. The driest
humidity will be across Northeast Texas and Southeast Oklahoma
the next couple days. There are small rain chances in the forecast
late today into this evening across portions of North Louisiana,
Southeast Oklahoma and Southwest Arkansas but if we see these
storms, they will be few and far between.
