- Warm front briefly and associated scattered showers moves back inland Thursday, but another cold frontal passage is forecast Thursday night.

DISCUSSION

Issued at 1247 AM CST Tue Nov 3 2026

Cold frontal boundary and associated thin band of showers and thunderstorms is currently tracking across northern and western Tx. This front and precipitation should be making its way into the Brazos Valley 5-7am, the US59/I69 corridor 1-4pm, and off the coast just before sunset. Instability-wise, things aren't overly impressive for a widespread severe wx threat. That said, we'll be keeping an eye out for an isolated strong to severe storm or two. Best upper diffluence should be situated across northern zones this morning and also east of the I-45 corridor into mid-late afternoon. We'll also monitor for any weak seabreeze/baybreeze that might try to develop prior to the fronts arrival that could briefly enhance some llvl convergence near the coast late in the day. Primary threat of any isolated strong cells would be 25-45mph wind gusts.

Otherwise, look for decreasing cloudiness and a return to seasonable conditions tonight and Wednesday. The front will return north as a warm front late Wednesday night & Thursday bringing increasing cloudiness and possibly some scattered showers back into parts of the area as the day progresses. By Thursday evening, chances further increase (moreso I-10 southward) as moisture availability becomes better and we see another cold front move across the region during the overnight hours.

Models aren't exactly on the same page in terms of the mid level pattern heading into the weekend. GFS indicates a quasi-zonal flow before ridging builds overhead. ECMWF/UKMET/ICON show we might see either a cutoff low and/or deepening trof across Mexico and southern Texas. Either way, seasonable wx probably won't be all that much different inland with temps close to normal and rain chances fairly low. Exception might be near the coast and in the Gulf water where POPs will be higher along with breezier winds/elevated seas. 47

AVIATION

(12Z TAF Issuance) Issued at 440 AM CST Tue Nov 3 2026

A broken line of showers/storms are on approach to the region in association with a cold front that will push through the area today. Out ahead of the front, there is a mixture of IFR/MVFR/VFR ceilings with the lowest values being along the coast and nearby the front. Patchy fog and reduced ceilings remain possible over the next few hours closer to the coast. Also can expect reductions in ceilings and visibilities in and around any showers/storms. The line of showers and storms will begin to push into CLL over the next hour or two. Elsewhere, expecting SH/TS timing of ~16-20Z for the Houston metro terminals, and between 18-22Z for the coastal terminals.

Southerly winds this morning become northwesterly behind the front but stay near or below 10 kt for the most part...except along the coast where winds may peak near 15 kt going into the evening. Drier air filtering in behind the front will lead to VFR conditions prevailing this evening into Wednesday as skies gradually clear.

MARINE

Issued at 1247 AM CST Tue Nov 3 2026

Light to occasionally moderate south winds are expected into the afternoon. A cold front, and associated thin broken band of showers and thunderstorms, will push off the coast in the late afternoon and early evening hours. Northwest to north winds will increase behind the front, and a Small Craft Advisory may be required for a short time period tonight in the Gulf waters until speeds diminish Wednesday morning. Onshore flow will resume Wednesday night as the boundary moves back north as a warm front. Another cold front is forecast Thursday night. 47
