SHORT TERM

(Tonight through Monday night) Issued at 1229 PM CST Sun Nov 1 2026

The latest GOES East Water Vapor imagery showers an upper level low centered over western Nevada, with broad southwesterly flow and ample mid-level moisture out ahead of it. This will be our next weather maker, sending a cold front through the region late Monday night through Tuesday morning. Until then, quiet weather along with shortwave ridging will result in warm and dry weather both today and tomorrow. Temperatures should warm into the lower to middle 80s for most locations, with the exception being over the Southern Edwards Plateau and northern Rio Grande Plains where persistent low level clouds and easterly flow will keep temperatures in the mid to upper 70s today.

For tonight, continued east to southeasterly low level flow will result in mild and somewhat humid weather for early November. The NBM has been struggling with this warmer airmass, so low temps were bumped up yet again tonight and tomorrow night to account for the warmer consensus. Monday will start in the mid to upper 60s with a few spots possibly not dipping below 70 degrees. More widespread low clouds are expected Monday morning as low level moisture pools over the region ahead of the approaching cold front slated to arrive early Tuesday. Temperatures are expected to climb into the 80s for most areas Monday outside of highs in the mid to upper 70s over the Southern Edwards Plateau and Western Hill Country. Monday night will once again feature muggy and mild conditions, but this will be the last warm night as cooler and drier air arrives behind a cold front moving in at the start of the long term period.

LONG TERM

(Tuesday through next Sunday) Issued at 1229 PM CST Sun Nov 1 2026

The cold front mentioned above arrives Tuesday morning and should exit the region by early Tuesday afternoon. Since this front will arrive before peak heating, instability will be lacking, however, there is enough deep layer shear to warrant a Marginal Risk (Level 1 of 5) along and west of the I-35 Corridor Monday night into Tuesday morning. The primary hazards would be large hail and damaging wind. Storms should move through quick enough to limit any sort of flooding risk. Winds will ramp up a bit behind the front, but won't be nearly as strong as our front a couple weeks ago. Drier air will move in behind this front, setting the stage for a beautiful second half of the week with cool, crisp mornings in the 40s and 50s and afternoons in the 70s. Another front may approach by the end of the week, but for now, this front looks dry.

AVIATION

(18Z TAFS) Issued at 1133 AM CST Sun Nov 1 2026

MVFR ceilings linger in the west impacting KDRT for another couple of hours before VFR conditions return to all of South Central Texas through tonight. An east to southeast wind generally remains at or below 10 mph through tonight, though some gusts up 20 knots are expected along the Rio Grande. Wind increases over higher elevations during the overnight hours then increases over a majority of the area Monday morning. Ceilings drop to MVFR/IFR levels closer to sunrise Monday with some areas of fog as well.
