KEY MESSAGES

Updated at 1130 AM CDT Tue Oct 13 2026

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

- Morning fog will be possible early to mid morning Wednesday and Thursday.

- 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 Friday) Issued at 1130 AM CDT Tue Oct 13 2026

Mostly a temperatures forecast through the week with a (strong of this time of year) H5 ridge builds across the southeast US. The 595 DAM ridge will help us warm into the 90s for most of the region through the week. That said surface high pressure will remain in control and humidities appear to be more on the comfortable side, so heat index values will be held down closer to actual temps. That said, as we have seen this morning radiation fog will be possible across the region each morning. Needless to say, if we can manage to get some higher clouds overnight, fog potential will be more limited. The lower spots such as the Pearl River and Pascagoula River basins will be most prone to morning fog. (Frye)

LONG TERM

(Friday night through Monday) Issued at 1130 AM CDT Tue Oct 13 2026

Globals are in agreement that a dry cold front will push through the region Friday night or early Saturday. This will usher in much drier and cooler temperatures across the region. At the surface, winds will also increase from a northeasterly direction with some gusts approaching wind advisory thresholds. Temperatures will be the big story with afternoon highs dropping from the upper 80s and lower 90s during the short term to struggling to approach 80 on Saturday. The H5 trough axis will position mostly east of the region, so higher upper heights start to build in from the west, which means a bit warmer signal toward the end of the forecast period. However, with low RH values, expect overnight lows to comfortable be in the upper 50s to lower 60s...warmer temps around the warmer bodies of water. (Frye)

AVIATION

(18Z TAFS) Issued at 1130 AM CDT Tue Oct 13 2026

Outside of potential morning fog Wednesday, VFR conditions can be expected across the region. IFR in fog between 10z and 15z, but otherwise light and variable winds expected. (Frye)

MARINE

Issued at 1130 AM CDT Tue Oct 13 2026

Winds and seas remain rather benign across our local waters. Winds of 5 to 10 knots and seas of 1 to 2 feet can be expected through much of this week as high pressure builds into the region. Toward the end of the week a strong cold front will move into the region increasing winds and seas with likely Small Craft Advisories or perhaps even Gale conditions this weekend. (Frye)
