DISCUSSION

Issued at 121 AM CDT Fri Mar 27 2026

Upper level high pressure remains in control over S TX, leading to unseasonably high temperatures again today. However, a cold front is forecast to move through S TX tonight through Saturday bringing near normal temps for the weekend.

Gusty S-SE winds later this morning will decrease and shift to the east this afternoon as the cold front moves into Central TX. Winds are expected to become light to moderate from the northeast, then will shift north overnight as the front moves through S TX. This will not last long as the front lifts north as a warm front and winds shift back to the east and southeast by Saturday evening. Well above normal temperatures return early next week.

There is a low (15-25%) chance of light showers along the Rio Grande and across the southern Coastal Bend Friday night into Saturday morning as the cold front moves through S TX. However, rainfall amounts are expected to be <0.05". Most locations will remain dry with no significant rainfall through the upcoming week.

AVIATION

(12Z TAFS) Issued at 628 AM CDT Fri Mar 27 2026

Majority of South Texas sits under VFR conditions early this morning, with the exception of areas along and a county west of HWY-281 where MVFR ceilings are present. There remains the chance for pockets of MVFR ceilings to pass over the Coastal Plains sites the next hour or two. However, VFR conditions will prevail across all sites by 15Z. Southeasterly winds will be weaker today at a sustained 10-15 knots this afternoon before a cold front pushes through tonight into early Saturday morning. Winds will shift out of the north to northeast in the wake at around 15 knots with gusts to 20-25 knots. There is only a low (20%) chance of showers along the frontal passage, way too low to include any mention at terminals at this time.

MARINE

Issued at 121 AM CDT Fri Mar 27 2026

A gentle to moderate south to southeast flow (BF 3-4)is expected today with an occasional fresh breeze (BF 5) for bays and nearshore waters south of Port Aransas. A cold front tonight will shift winds to the northeast on Saturday and will strengthen to a fresh breeze (BF 5). Small Craft Advisory conditions are possible Saturday. A gentle to moderate (BF 3-4) east to southeast flow returns by Saturday night and continues into next week. There is a 20-50 percent chance of showers associated with the cold front over the coastal waters and extending to the open gulf waters late Friday night into Saturday morning.

FIRE WEATHER

Issued at 121 AM CDT Fri Mar 27 2026

Afternoon humidity values will continue to fall between 20-30% over the Brush Country and western Coastal Plains each afternoon this weekend through next week. The low RH values combined with breezy east-southeasterly winds most afternoons and dry to critically dry fuels, will result in elevated to near-critical fire weather conditions. A cold front is expected tonight into Saturday morning which will bring a wind shift from the east to northeast before the front lifts back northward on Sunday. There is a low (15-25%) chance of wetting rains associated with the cold front along the Rio Grande and across the southern Coastal Bend tonight through Saturday morning. Rainfall amounts are expected to be <0.05" with most locations remaining dry.
