Synopsis.
the gradient between high pressure centered over the northern appalachians and a weak trof over the northern gulf of mexico will allow for continued moderate easterly winds and seas. Taking near-shore and buoy observations, winds stayed up higher than expected today and are expected to increase tonight within a tightening weather gradient. A small craft advisory has been issued for coastal waters through tonight for elevated winds and seas. The proximity of the trough will also allow for continued development of scattered showers or Thunderstorms over the next couple of days.
wave heights will decrease temporarily as a frontal boundary sweeps into the gulf, bringing behind it a surge of elevated offshore flow. The strongest period will be on Saturday, where we could see winds of 20 to 25kts sustained with higher gusts right under gale force.

UPDATE
Issued at 944 PM CDT Tue Oct 3 2023
A small craft advisory remains in effect as off shore buoys show sustained winds over 20 knots and gusts near 30 knots. Skies will clear through the night with the last of the rain fading away around midnight. Winds will remain from the south-southeast through the night.
SHORT TERM
(Tonight through Thursday night)
Issued at 259 PM CDT Tue Oct 3 2023
A quick glance at surface analysis products shows two very large features: high pressure centered over Ohio which extends upwards into 500 mb right over the ArkLaTex region, and large trof moving into the central US.
Looking more closely at the southeast, there is a convergent area of showers and thunderstorms located from southeast to north- northwest between Houston and Beaumont. This corridor has been highlighted for the possibility of urbanized flash flooding, especially where intense rain rates fall. Mesoanalysis shows PWATs 2.0 to 2.3 inches within the core of the rainfall. It is likely for this core to wobble west or east overnight; westward movement would be less rain/flood chance for Deep Southeast Texas, eastward would be higher.
This boundary of higher rain chances in Deep Southeast Texas prevails into tomorrow. However, the gradient between wet and dry will be tight as high pressure at the sfc and 500 mb level both act to keep as much of the area as dry as possible. This will also allow for temperatures over Louisiana parishes to warm into the low 90s.
The large, lumbering trof starts sliding eastward late Wednesday, dragging with it a sfc cold front which arrives to the area on Thursday. Midday Thursday, it looks like forcing along the upper levels lifts out causing the frontal boundary to slow down and stall over the area. Forecast PWATs ahead of the front's arrival aren't the best for getting efficient rain-makers like we need.
Unfortunately, right now, it could be a cloudy, but fairly low-QPF fropa.

LONG TERM
(Friday through next Monday)
Issued at 259 PM CDT Tue Oct 3 2023
We begin the long term within a transitional period, with Thursday's cold front to our south and a secondary front approaching from the north. The airmass between these boundaries will still be somewhat warm and moist, with PWATs on Friday morning expected to range from 1.3" inland to 1.6" near the coast. The combination of decent moisture overhead as well as lift associated with the front to our south will likely result in scattered convection across the southern half of the region on Friday. Kept small rain chances in place further inland as well, just to account for the possibility of some isolated convection spreading further north however, overall guidance is pretty consistent in keeping the best rain chances south of I-10 and offshore for Friday. Temperature wise, Friday will near seasonal norms, with highs in the mid 80s.
Late Friday into Saturday, the secondary cold front finally makes it way through the forecast area, bringing with it a long anticipated cool down that will result in a very pleasant weekend for the CWA.
By 12Z Saturday, PWATs will have fallen into the 0.6-0.8" range areawide, which is near the 10th percentile according to SPC climo.
Dewpoints will fall into the upper 30s to mid 40s through Sat afternoon, while RH values will bottom out in the upper 20s to mid 30s. At the same time, a tightening pressure gradient overhead between the departing front and building high pressure over the Plains will result in breezy conditions for Sat, with frequent gusts to 20-25 kts likely. Breezy winds in combination with a much drier airmass may pose a threat for increased fire danger, which we will continue to monitor over the coming days.
Surface high pressure begins to settle over the Gulf Coast by Sunday, where it will then meander through Tuesday. This will allow winds to relax quite a bit, while also keeping the region dry and mild through the end of the short term period. Temperature wise, Sat and Sun will bring highs in the mid 70s to near 80, while overnight lows will fall into the upper 40s to mid 50s. Temps begin to moderate a bit by Monday as moisture slowly returns, with highs in the upper 70s to mid 80s Mon and Tues.

(06Z TAFS)
Issued at 1158 PM CDT Tue Oct 3 2023
Saw little reason to deviate significantly from the previous forecast. Convective activity has decreased substantially in terms of coverage and intensity, with just some light showers noted on radar. Additional activity is expected to develop toward WED morning, but again should be focused primarily to our west. ESE winds will remain elevated KLCH and KBPT overnight, and increase/become gusty mid to late morning WED. VFR is expected to prevail.

FIRE WEATHER
Issued at 259 PM CDT Tue Oct 3 2023
Dry afternoon conditions will improve modestly tomorrow and Thursday, however a fire danger statement is in effect tomorrow for CenLA from 10 AM until 8 PM tomorrow. RH values 30 to 40 percent are expected in this area, along with gusty daytime surface winds and slightly elevated 20 ft winds similar to today.
These conditions may be conducive for fire formation or spread. From Thursday, a more humid airmass works into the region, where it will remain until the weekend.
Starting Saturday, we will see a drastic drop in dewpoints. Temps will be in the 70s with dewpoints in the upper 30s to 40s. This will yield RH minimums in the mid 20s to 30s for what will be the remainder of the long term forecast (early to mid next week). To make matters worse, winds over the weekend, Saturday in particular, will be elevated around 15 to 20 MPH sustained with higher gusts.
