DISCUSSION

Issued at 131 AM CDT Tue Sep 1 2026

Tropical Storm Edouard continues to move toward the Upper Texas Coast and is forecast to make landfall late Tuesday/early Wednesday. What does that translate for us here in South Texas? Unfortunately for most, just some extra high clouds. For those closer to the Victoria Crossroads, they'll have increased chances for scattered showers/thunderstorms (20-30% chances) this afternoon through Wednesday morning. Most of the highest totals will remain generally along and east of the I-45 corridor, and only a few tenths of an inch near the Victoria area. We'll continue to monitor the low track as any wobble could give the Victoria Crossroads closer to the higher PWATs (>2.10") meaning more efficient rainfall rates. Given the distance from Edouard, a moderate risk for rip currents will exist north of Port Aransas through Wednesday. While the extra cloud coverage will be welcomed, the HeatRisk will continue to top out in the major/extreme risk level (level 3 and 4 of 4) most afternoons.

Mid-level high pressure across the Southeast US will continue to keep the hot weather in play through the weekend, but it will also allow weak disturbances to move to the west around the southern periphery in the Gulf. What this mean for this Labor Day weekend will be increased chances for seabreeze showers/storms with greatest chances for storms primarily confined to the coastal plains. While not a complete washout, anyone planning outdoor activities with few locations for shelters (like the beach), will need to keep the car unlocked for quick access in the event of a shower (and the occasional AC break).

AVIATION

(12Z TAFS) Issued at 619 AM CDT Tue Sep 1 2026

Mostly VFR conditions prevail for most terminals. Maintained VCSH for KVCT which may briefly see showers associated with any rain band that develops from Tropical Storm Edouard and the PROB30 group for the possibility of thunderstorms.

MARINE

Issued at 131 AM CDT Tue Sep 1 2026

Expect gentle to moderate southerly winds with 2-3 ft seas. Nearshore and offshore waters north of Port Aransas have moderate chances (30-50%) of showers and storms this afternoon and drops to 20-30% chances through the weekend.

FIRE WEATHER

Issued at 131 AM CDT Tue Sep 1 2026

Minimum relative humidity values each afternoon will drop to as low as 25-30% through Friday. While Energy Release Component values are forecast to remain in the 70th-89th percentile, weak afternoon winds will keep the fire risk at just elevated conditions. Overnight winds will increase to 15-20 mph, but this will occur at the same time RH recoveries begin. Less than 10% rain chances can be expected through the week, though closer to 20-30% along the coastal zones this weekend.
