DISCUSSION

Issued at 140 PM CDT Thu Sep 3 2026

Hot temperatures continue across the area today with high pressure still in control. The leftover disturbance from what was Edouard remains northeast of the region of the Southeast Texas. This mid level disturbance will drift toward our area and linger through the weekend. This, combined with increased deep moisture will bring rain chances to the area for the first time in a little while. VCT area will have the highest chances with up to 50% Friday through Sunday. That disturbance opens up/washes out later in the weekend, but another wave of tropical moisture will be on its heels keeping the potential for enhanced sea breeze activity through the first part of next week.

Temperatures are a bit tricky with the increased cloud cover and rain potential. There is a low chance (25%) that high temperatures in the Victoria Crossroads don't top 90 degrees tomorrow, but the majority of guidance suggests rain coverage will be limited enough to allow temperatures to once again make it into the mid and possibly upper 90s. Will stick with the higher temps in the forecast, but realize it's not out of the question for it to be several degrees cooler in that area. We should drop temps a notch through for the weekend thanks to the increased moisture. Well timed showers/storms could keep temps into the lower 90s for a few locations. Seasonal temperatures continue into next week.

AVIATION

(18Z TAFS) Issued at 140 PM CDT Thu Sep 3 2026

Mainly VFR conditions are expected through this forecast period. Showers and storms today remain well northeast of VCT, but a few TS could move into the VCT area by tomorrow. Have included Prob30 for this late morning into the afternoon. A few streamer showers would be possible along the coast earlier than that. Think low clouds remain largely FEW to SCT through this period, but a brief MVFR CIG can't be ruled out toward morning or within showers/storms tomorrow.

MARINE

Issued at 140 PM CDT Thu Sep 3 2026

Gentle to moderate south to southeast flow with 2-3 ft seas is expected through the period. Isolated to scattered showers and thunderstorms are possible beginning tomorrow and persisting each day into next week. The best chance tomorrow will be north of Port Aransas.
