KEY MESSAGES

Updated at 1233 AM CDT Sat Oct 24 2026

- Mild to warm conditions continue into and through next week.

- Periodic rain chances next week; highest (30-60%) chances late week.

SHORT TERM

(Today through Sunday) Issued at 1233 AM CDT Sat Oct 24 2026

Mid-level ridging will continue to inch slowly to the east through the short term with the center of the ridge axis aligning atop of the Louisiana to Mississippi Valley region by Sunday night. This turns the flow aloft more southwesterly between the exiting ridging and the continued troughing across the southwestern CONUS. Across the lower levels, a more southeasterly component to the flow has established and slightly intensifies into today. This should result in moderate afternoon breezes (stronger than the past few days) through this weekend and a little stronger low-level moisture advection. This would be most noticeable at night where it trends a bit more humid while at least some low-level cloudiness starts to return during the overnight into each morning. There could be a couple stray streamer showers as well during the mornings. If to form, these should focus mainly from the San Antonio metro area or Coastal Plains and any points south-southwest of there. Afternoon mixing will lower the dew points, especially Sunday, which will scatter out the early day low to mid-level level clouds. High clouds, however, will be on the increase as we advance through the weekend. The daytime highs for Sunday are forecast to be a couple degrees lower compared to today as a result of how thick those high level clouds become.

LONG TERM

(Sunday night through Friday) Issued at 1233 AM CDT Sat Oct 24 2026

The main low and vorticity with the troughing across the Southwest CONUS will quickly eject northeastward towards and into the High plains through Monday. However, there should be some leftover shortwave energy that lingers behind within the southwesterly flow that crosses through Texas Monday through Tuesday night. This will bring in some mid-level moisture into play and combines with the lower level moisture to squeeze out some low (15-30%) rain chances across the region Monday night through Tuesday. This QPF signal remains quite light with little, if any, thunder potential.

The shortwave exits the region by Wednesday but the region remains underneath a southwesterly flow aloft. several of the medium range guidance does continue to spit out some spotty qpf Wednesday afternoon across mostly the Coastal Plains with the lingering moisture, perhaps with a seabreeze or wind surge. Rain chances are then forecast to climb late week. This would be due to multiple perturbations arriving within the Southwesterly flow aloft. The latest medium range guidance has become a bit more shy in regards with the main vorticity and moisture from Hurricane Vance being involved, but still does show some pieces of energy and moisture possibly stripping off the tropical cyclone and perhaps becoming absorbed into the arriving perturbations within the southwesterly flow aloft. The QPF signal is not overly impressive across our area but is certainty better than with the rain chances earlier in the week.

Temperatures remain warm and steady through next week with daytime highs mostly ranging from the mid 70s to the mid 80s. Pending how thick cloud cover and how much rain coverage becomes, a day or two may trend a little lower. Overnights remain mild and a bit humid with lows ranging mostly from the mid 50s to the mid 60s.

AVIATION

(06Z TAFS) Issued at 1233 AM CDT Sat Oct 24 2026

VFR conditions are forecast for the local area sites for the next several hours. However, MVFR cigs are forecast to develop mid to late overnight into Saturday morning. By mid Saturday morning, low cigs lift to VFR conditions and remain that way for the rest of Saturday afternoon into Saturday evening. A southerly wind flow is in place and persists through the forecast period. Wind gusts between 15 and 25 knots are forecast for the afternoon along and west of Highway 281
