KEY MESSAGES

- Few storms may clip portions of the Piney Woods area early today... cannot fully rule out a stronger storm or two.

- Isolated strong to severe storms will be possible over the area this afternoon and evening.

- Gradual warming trend with temperatures reaching into the upper 80s to lower 90s this weekend.

- Above normal temperatures continue during the early to middle part of next week, with at least isolated showers and thunderstorms possible over portions of the region each day.

DISCUSSION

While currently quiet over SE Texas early today, there is an ongoing convective system moving across NE Texas, which has potential to reach the northern borders of our CWA a few hours from now. Broadly the parameter space is weaker, especially for thermodynamics, and model guidance shows these storms dying off as their reach our area early today. However, I wouldn't completely rule out a risk of one of these stronger storms managing to hold together by the time it reaches our area. We'll also have a similar risk of severe storms during the daytime as well. SFC CAPE should reach around 1700-3500 J/KG with 500mb shear around 30-45 knots. The severe weather threat has largely continued to trend further north/northeast, with more favorable lift edging further out of our area today and even moreso on Sunday. Even still, steep midlevel lapse rates of 7.0-8.0 DegC/km and particularly deep CAPE around -10C to -30C still suggest the potential for larger hail. CAMs are bear on convection throughout the weekend due to a cap around 850mb, though again it may take just a singular shortwave or impulse to overcome the cap, so we'll continue to keep a particular close eye on things through each afternoon in case any storms can manage to pull together.

For next week, a shortwave trough is still expected to fill northeast across the Plains, sending a cold front towards SE Texas. This front should slow and stall around the Brazos Valley/Piney Woods, though some isolated showers and storms are still in play for our northern zones. A subtropical mid-level high then builds in from the south on Tuesday, establishing more zonal flow aloft and allowing for another series of shortwaves and impulses to move over SE Texas. Expect rising rain chances through late next week. Around Friday, another mid/upper level shortwave trough will move through Texas, pushing a more robust cold front through the area. Anticipate cooler and breezy weather heading into the next weekend.

AVIATION

(12Z TAF Issuance) Issued at 603 AM CDT Sat Apr 25 2026

Widespread MVFR ceilings with intermittent periods of IFR ceilings will continue over through the morning hours before ceilings lift to VFR by 18Z. MVFR ceilings may linger into the late morning/early afternoon hours along the coast. Southeasterly to southerly winds will prevail today with wind speeds around 5-10 kt. Another round of MVFR to IFR ceilings expected to filter in from south to north later this evening into Sunday morning. There is potential for reduced visibilities as well due to patchy fog mainly in the 09Z-14Z timeframe on early Sunday morning.

Light to moderate southeasterly winds should continue through the next several days. Elevated water levels around 2.5 to 3.0 feet above MLLW are expected at each high tide cycle through early next week. Isolated showers and thunderstorms will be possible each day through the weekend. A slight increase in winds and seas are expected beginning around Tuesday next week.
