KEY MESSAGES

Updated at 1245 AM CDT Thu Sep 3 2026

- Daily shower and thunderstorm chances increase especially on Friday, with scattered to numerous showers and storms continuing into early next week. A few storms could become strong with locally strong wind gusts and isolated flooding from intense rainfall rates the primary concerns. A mainly morning waterspout risk will also continue each day across marine areas.

- Highest heat index values of 103 to 107 are expected mainly Sunday and Monday, and a few areas may see values of 108 to 110. Heat related products may be needed for portions of the area early next week.

DISCUSSION

Issued at 1245 AM CDT Thu Sep 3 2026

A gradually lessening of the upper high pressure area centered over the Tennessee Valley to a more elongated ridge from the central and southern Plains to the Atlantic will occur through late in the day on Friday. This ridge will then retrograde westward over the central CONUS through the remainder of the week as an upper trough digs southward along the Eastern Seaboard. The mid-lower high pressure area over the Tennessee Valley will also gradually weaken while a mid-lower easterly wave moves west- northwestward over the eastern and northern Gulf today through Friday.

An enhanced deep easterly flow between these two systems will allow deep moisture to enter into the region with PWATs increasing up to around 2.4" by noon Friday. Models are now showing a central closed low pressure area as low as 925mb embedded within the wave that should reach southern Louisiana by midnight Friday night with a possibly weak surface low pressure area forming somewhere across the northeastern Gulf tonight. For today, we are only expecting isolated to scattered afternoon showers and storms mainly south of Highway 84, followed by isolated to scattered afternoon showers and storms along the coast overnight. A substantial increase in PoPs will occur through the remainder of the week, with numerous to widespread coverage on Friday and Saturday. Can't rule out a few strong storms or even perhaps isolated areas of locally heavy rains resulting in mainly nuisance type flooding, along with waterspout development possible mainly during the morning hours each day over the marine area.

We remain in this wetter pattern through at least Monday as the base of the Eastern Seaboard upper trough remains over the southeast states along with a possibly backdoor cold front entering into the forecast area on Sunday and then meanders through Monday before dissipating. Therefore, we are still expecting daily occurrences of scattered to numerous daytime showers and storms during the afternoon/evening hours over land zones and the morning hours coastal/marine areas through Monday, and potentially into midweek.

Highs will be in the lower to middle 90s today, and range from 88 to 93 degrees Friday and Saturday before climbing back into the lower to middle 90s on Sunday. Daytime heat index values of 100-105 are expected through the remainder of the week, trending to 105 to 110 degrees early next week. /22

AVIATION

(06Z TAFS) Issued at 1245 AM CDT Thu Sep 3 2026

Expect VFR conditions for all area terminals through early this morning. Expecting to see an increase in SCT TSRA/SHRA primarily later this afternoon from 17-19Z through 00Z, with greater coverage potential for KMOB/KBFM. Only main impacts in any SCT TSRA/SHRA will be periodic lower VIS/CIGS briefly lowering flight categories from heavy rain and gusty winds on the order of 25-35kts. Otherwise, winds will remain light prevailing form the east during the day. /008

MARINE

Issued at 249 PM CDT Wed Sep 2 2026

A light to occasionally moderate diurnal flow pattern is expected through the remainder of the week and into the weekend, with offshore winds expected at night and onshore winds during the day. Rain chances will also increase over the coming days, especially on Friday. A few waterspouts will be possible each morning. /29
