DISCUSSION

Issued at 1132 AM CST Thu Nov 5 2026

A fairly tranquil weather day will be encountered when southeast Texans step outside on this 5th of November. Expect plenty of sunshine, though some clouds are trying to push in from the southwest. Temperatures should skew a tad warmer than normal, likely peaking just above 80 at most spots this afternoon. Overnight temperatures should drop into the 50s and 60s, with patchy fog in a few areas. Could be a few thunderstorms over the Gulf this evening due to an approaching shortwave. The only land areas we need to watch is near Matagorda Bay. For now, most of the activity is expected offshore.

A cold front situated over W Texas will push eastward, crossing our CWA early Friday. Current temperatures in the Texas Panhandle are only in the 40s with gusty winds. We don't expect temperatures that cold to reach SE Texas. But we expect a downward trend in temperatures that begins on Friday as a ~1025 MB sfc high builds southward over the plains in the front's wake. The northern half of the CWA is expected to be in the mid/upper 70s on Friday, while areas farther south likely manage one more day up around 80 degrees.

The aforementioned high continues its southward drift while the upper level pattern changes over the weekend. A trough is evident over W CONUS. The southern edge of the trough axis features a strong vort max. This vort max is expected to break off, evolving into a more cut-off low structure as it pushes across SW CONUS. By Saturday, we expected this low to be centered over northern Mexico, enhancing an increasingly diffluent and vort max abundant mid/upper jet over Texas. For SE Texas, the pattern aloft may only result in increased clouds on Saturday. But by Sunday, we suspect rainfall chances will increase. Increasing clouds and modest CAA from the southward drifting sfc high should lower afternoon temperatures. Saturday is expected to average in the mid 70s. By Sunday, most locations are forecast to remain in the 60s. Highest rain chances on Sunday are generally west of I-45. However, most of the guidance is showing at least a little shower activity drifting into our eastern zones on Sunday.

The cut-off low is expected to push northeastward on Monday- Tuesday, possibly phasing with the polar jet by mid-week, helping to amplify the jet southward over E CONUS during the second half of the week. This may trend the pattern colder across E CONUS. Meanwhile, global deterministic / ensemble / AI guidance suggest another cut-off low or trough could be pushing across SW CONUS during the same time frame. What does this mean for SE TX? The influence of the potential cut-off low / trough may not be felt until the very end of the week. So PoPs for most of next week are low. After another day in the 60s on Monday, we are expected mostly 70s next week with lows in the 40s and 50s. Perhaps the only temperature wild card will be any possible backdoor fronts that could bring some of the colder E CONUS temperatures westward. AI models actually suggest this, but not until after the forecast period.

AVIATION

(18Z TAF Issuance) Issued at 1032 AM CST Thu Nov 5 2026

VFR conditions for this afternoon with mostly clear skies. Expect cloudiness currently across South TX/middle TX coast region to spread across the area tonight with BKN050-060 ceilings developing. A weak cold front will cross the terminals 09-14Z Friday. Light winds will become north 5-10 kts behind the front. Patchy MVFR fog is expected to affect KCXO/KSGR/KLBX 07-12Z prior to the FROPA.

35/MM* Discussion goes here.

MARINE

Issued at 1032 AM CST Thu Nov 5 2026

Scattered showers and a few thunderstorms are possible offshore this evening into tonight. Locally strong winds are possible with any thunderstorm. Otherwise, the primary concern will be increasing NE winds Friday into the weekend along with gradually building seas. Small Craft Advisory level conditions are possible over the Gulf as early as Saturday morning. Winds and seas are expected to peak on Sunday, with seas up to 8-9 feet possible offshore, and closer to 4-6 feet nearshore. Winds remain NE while decreasing on Monday into Tuesday.
