Fire Weather Planning Forecast for S MS and SE LA
National Weather Service New Orleans LA
537 AM CDT Wed Aug 12 2026
.DISCUSSION...
High pressure will dominate the region through the forecast with
that look for the heat to build and the rain chances to continue
to drop. Isolated storms are still possible today but after today
it may be next week before we see another storm in the area. The
rapid lack of rain over the last month and above to well above
normal temps we have been seeing is quickly leading to drought
concerns that may become problematic for fire weather concern in
the next few weeks. As for other fire weather concerns, winds
will be light and variable to calm overnight, and then winds
around 5-10 kts coming out of the southwest to southeast as the
seabreeze develops. Humidity values will be of no concern the
next few days generally remaining in the 40-60% range but by
Friday and into next weekend as we continue to dry out and heat
up min rh values will start to drop into the 30s across inland
areas.
