FNUS54 KLIX 180518 FWFLIX Fire Weather Planning Forecast for S MS and SE LA National Weather Service New Orleans LA 1218 AM CDT Mon May 18 2026 .DISCUSSION... Fire weather concerns are limited as moisture continues to move back into the area leading to gradually increasing rain chances. Showers and storms should mainly be limited to areas west of the I-55 corridor this afternoon and Monday, spreading eastward toward the I- 59 corridor midweek, and then becoming more area-wide Thursday through the weekend. Over the next 7 days forecast rainfall totals vary from 2-3 inches across northwestern areas to less than an inch for extreme southeast Louisiana and much of the Mississippi coast, though obviously point-specific totals will depend on exact locations of any heavier thunderstorms.
