KEY MESSAGES

Updated at 112 AM CDT Mon Oct 12 2026

- Near record high temperatures are expected for much of the workweek with little or no precipitation.

- A cold frontal passage on Friday will bring cooler weather to the area for next weekend along with potentially hazardous marine conditions.

SHORT TERM

(Now through Thursday) Issued at 112 AM CDT Mon Oct 12 2026

An upper level ridge over the northern Gulf will remain over the region through the short term period. Subsidence will keep rain chances close to zero and with surface high pressure winds will be on the light and variable side. The forecast will mostly revolve around the temperature forecast. With the H5 594dam ridge over the southeast, temperatures will have no issue warming well into the upper 80s and lower 90s...nearing record values for this time of year. With RH values on the low side, expect more comfortable overnight lows. There also will be possible very shallow ground fog in the lowest spots across the region. (Frye)

LONG TERM

(Thursday night through Sunday) Issued at 112 AM CDT Mon Oct 12 2026

Upper ridging will be centered over South Carolina Thursday night, with the surface high off the Georgia and Carolina coasts. An easterly wave will be moving northward around the west side of the ridge on Friday. As this happens, the upper ridge will build back into the lower Mississippi River Valley over the weekend, behind a cold front that will move across the area Friday night.

While the frontal passage isn't expected to bring any significant rainfall, it is expected to usher in cooler temperatures. While highs to end the work week will be in the upper 80s and lower 90s, they will be departing behind the front. By Saturday, highs across the area are expected to be mainly in the 70s. Ahead of the front, lows will be mainly in the 60s. but behind the front, lows will be in the 40s and 50s in most areas. Warmer and more moist air will return just beyond the end of this forecast package period, which could bring a little light precipitation to lower portions of the Louisiana coastal parishes Sunday or Monday. So enjoy the cooler weather next weekend. (RW)

Toward the end of the week a strong cold front will move into the region increasing winds and seas with likely small craft advisories next weekend. (Frye)
