KEY MESSAGES

- Fog will remain a possibility nightly through the weekend, especially in the coastal areas.

- Unseasonably warm weather will continue through the start of next week. - Few cold fronts will try but are unlikely to reach SE Texas next week.

DISCUSSION

Issued at 1042 PM CST Sat Feb 28 2026

Another night of patchy fog is expected for portions of SE Texas tonight into Sunday morning, with the potential for dense fog developing along the coast and along/east of I-45. Observations as of 11pm has widespread reports of hazy conditions (2-6mi) visibilities, but expecting some dense fog to develop within the next few hours - again mostly along the coast and for areas along and east of I-45. Fog that does develop will dissipate within a few hours of sunrise giving way to mostly sunny skies and temperatures rising into the low 80s for Sunday afternoon. Another night of patchy fog is possible Sunday night into Monday, but SREF and HREF probabilities of dense fog are much lower compared to the past few nights.

The abnormally warm weather will continue through the workweek as upper-level ridging moves in Monday into Tuesday, and then replaced by southwesterly flow aloft Wednesday through the remainder of the week. High temperatures will be in the low to mid 80s through the workweek (with some spots potentially rising into the upper 80s by the end of the week). Overnight lows will be in the mid to upper 60s by midweek, and then upper 60s to potentially low 70s by week's end (which will be approaching the normal high temperature for this time of year).

For the first time in awhile, we actually have some chances to see some rainfall across SE Texas this week. The first chance will be Wednesday into Thursday as a cold front approaches from the northwest, then stalls to the northwest of the region. While the best dynamics appear to stay to the northwest of our area, a combination of daytime heating, passing weak disturbances embedded in the southwesterly flow aloft, and PWATs rising to 1.3-1.5" ahead of the front may lead to scattered showers in portions of SE Texas on Wednesday. PoPs continue for the Brazos Valley and Piney Woods on Thursday as the stalled front lingers before retreating back to the north. The next chance for rain will be over the weekend as the next cold front approaches from northwest. At this time, there is higher uncertainty with this front on how far south it makes it before stalling. It may stall in a similar position to Wednesday's front, but could sag further south in SE Texas and thus increasing rainfall chances. We appear to be in a similar upper-level pattern as we head into the second week of March, so I'd expect us to see continued warm/humid conditions and chances of rainfall.

AVIATION

(12Z TAF Issuance) Issued at 449 AM CST Sun Mar 1 2026

IFR-MVFR ceilings will continue across SE TX sites through around 14-15Z. Reduced visibilities due to areas of patchy fog will also continue through around 15Z. Quickly after, clouds will lift and scatter out and fog will burn off. The pressure gradient will tighten today and a 25-30 KT llvl jet will develop, leading to stronger winds. Expect SE winds to increase to 10-15 KTS with gusts of 18-23 KTS this afternoon. Winds will relax to around 10 KTS in the evening and to around 5 KTS late tonight into early Mon morning. IFR ceilings will once again be possible starting late Sun night and with the lighter winds, there is a chance for areas of fog to develop early Mon morning.

Cotto

MARINE

Issued at 1042 PM CST Sat Feb 28 2026

Main forecast concern through Monday will be the potential for patchy, dense fog developing nightly. As of 11pm, webcams and satellite imagery are showing some hazy conditions, but the expectation is that areas of dense fog will likely develop in Galveston Bay and our northern coastal waters through the night. We are not expecting as widespread dense fog like the past couple of nights, but mariners should keep weather aware and use safe boating practices if you encounter dense fog. Any fog that does develop is expected to dissipate by the mid-morning hours.

Some patchy fog is possible again Sunday night night into Monday, but the daytime heating on Sunday will warm SSTs, and thus likely limiting sea fog development even more.

Otherwise, expect continued low seas and light onshore winds through the next several days.
