KEY MESSAGES

Updated at 625 PM CDT Wed Oct 7 2026

- Dry weather continues through the weekend with near to slightly warmer than normal temperatures.

- No significant rain chances through the weekend, but low end rain chances return to the area early next week with more humid conditions.

SHORT TERM

(Tonight through Thursday night) Issued at 142 PM CDT Wed Oct 7 2026

Satellite imagery showed cloudless skies encompassing nearly our entire CWA, as sub-1 inch PW air has spread across most of South Central Texas. Weak flow will keep this dry continental airmass over the region through midweek. The ample sunshine will support highs in the mid 80s to low 90s this afternoon and again Thursday. Light winds and mostly clear skies will shape relatively crisp nights and mornings with lows in the upper 50s to 60s for most. On Thursday, the broad high pressure over our area and Tropical Storm Isaias in the Gulf will channel weak easterly low-level flow over South Texas with models depicting a modest 5-degree increase in 0-3 km dew points. A broad upper-level trough will move across the area, resulting in a slight uptick in rain chances near the Rio Grande late Thursday into early Friday as it interacts with this moisture, but the moisture return and synoptic lift will be weak and there likely won't be much more than a few localized fleeting showers.

LONG TERM

(Friday through next Wednesday) Issued at 142 PM CDT Wed Oct 7 2026

Late in the week, Tropical Storm Isaias is forecast to stay quite distant from our area, and direct impacts to our area will be negligible. Those with weekend plans for the Texas coast should refer to information from our neighboring NWS offices (CRP, HGX, and BRO) for further details regarding the risk of higher tides and rip currents.

South Central Texas will stay within the dry envelope of the passing trough into weekend, keeping conditions stable and dry. Daytime temperatures will continue to be warm, in the mid 80s to mid 90s, with overnight temperatures mostly in the 60s.

By late Sunday, the trough will clear our area, opening the door for moist southerly flow. This is forecast to raise overnight temperatures back into the low to mid 70s as muggier Gulf air returns, while highs could see some slight increases into the low to mid 90s as warmer Mexican plateau air takes the place of the outgoing trough. This pattern is a little more conducive to diurnal convection, and thus the forecast features isolated chances (10 to 30 percent) for showers or storms during the afternoons. Along the Pacific coast, a strong deep-layer trough will amplify this weekend into early next week, contributing to the southerly flow over our area. There is good model agreement in moisture from Tropical Depression Twenty-E in the Pacific eventually being caught up in this flow, but whether this could implicate South Central Texas early next week depends on whether the system tracks more west and misses our area entirely, or if placement farther east allows moisture to diffuse into our area. For now, both the GFS and ECMWF place the moisture plume west of our region. Ridging is favored to stay over the area through midweek next week, so temperatures should remain near to warmer than average during that period.

AVIATION

(00Z TAFS) Issued at 625 PM CDT Wed Oct 7 2026

VFR ceilings and light winds are expected over the next 24-30 hours. The only exception would be some breezy conditions at AUS, SAT, and SSF through 03Z. A general ENE to NE wind direction can be expected through the remainder of the forecast at the I-35 sites and out of the East and ESE at DRT.
