Updated at 609 PM CDT Sat Oct 24 2026

- Elevated fire danger will continue through the weekend. The current and worsening drought conditions and dry fuels combined with low humidity and slightly higher winds will lead to potential for rapid fire growth. Residents should obey all burn bans in place and exercise extreme caution with any open flames outdoors even in areas that do not currently have burn bans in place.

- Strong winds will continue to result in hazardous conditions for small craft across most coastal waters of southeast Louisiana and Mississippi through Sunday night.

Short Term

(Now through Tuesday night) Issued at 1224 PM CDT Sat Oct 24 2026

Strong and deep ridging will remain over the forecast area through Monday. The ridge axis will shift slightly to the east on Tuesday as a weak shortwave trough lifts out of the Four Corners, but a lack of moisture return will keep rain chances minimal through the short term period. With the center of the surface ridge to the north-northeast of the area, a persistent east- northeast wind will keep any low level moisture return at bay. Thus, a continuation of the conditions we have seen the past several days with clear skies, low humidity, and a larger than normal diurnal range of temperature will continue through Tuesday night. Highs will warm into the upper 70s and lower 80s each day and lows will dip into the low to mid 50s inland the upper 50s and lower south of the tidal lakes and along the immediate coast of Louisiana.

Long Term

(Wednesday through Friday night) Issued at 1224 PM CDT Sat Oct 24 2026

The dry pattern will persist through the end of the workweek even as the mid to upper level ridge axis becomes more centered over the eastern Gulf and southeastern CONUS. This dry pattern will be due to continued surface ridging centered to the north of the area maintaining a prevailing east-northeast wind pattern. This pattern will limit low level moisture return and keep rain chances at less than 10 percent through Friday. Temperatures will also continue to exhibit a large diurnal range on the order of 25 to 30 degrees. Highs will warm into the upper 70s and lower 80s and lows will still cool into the low to mid 50s over inland areas and the upper 50s and lower 60s south of the lakes and along the coast. Overall, no significant change from the weather we've seen the past several days is expected as we move through next week.
