DISCUSSION

Issued at 1143 AM CST Sat Feb 28 2026

Above normal temperatures will continue through next week as a mid to upper level high builds over the area from west to east. Winds will be moderate out of the southeast during the day today and tomorrow with gusts to around 25 MPH. Tonight, winds will be lighter, allowing for another round of patchy to areas of fog to develop. However, confidence is not as high as it was yesterday as guidance is indicating 925mb winds to be elevated through the night which could mix down to the surface disrupting fog formation. Having said that, fog potential continues nightly through early next week, with potential diminishing around mid week with the arrival of stronger winds.

In terms of rain chances, these will increase to around 20-30% Wednesday into Wednesday night ahead of a closed low entering the Central Plains. The rest of the week will be mostly dry, though models have been trending wetter for next weekend with a couple of disturbances tracking in the southwesterly flow aloft. Chances for next Saturday are increasing to near 40%, but changes to the forecast are likely over the coming days.

AVIATION

(18Z TAFS) Issued at 1143 AM CST Sat Feb 28 2026

VFR conditions will prevail across area terminals through late tonight, before falling to a mix of MVFR to IFR levels Sunday morning. A return to VFR is forecast to occur around 15-16Z tomorrow. Winds will be out of the southeast this afternoon with a few gusts to 20 knots. Lighter winds return overnight, but will increase again to around 10-15 knots mid Sunday morning.

MARINE

Issued at 1143 AM CST Sat Feb 28 2026

Areas of fog remain possible at times through next week. Winds will strengthen to a moderate (BF 4) breeze this afternoon and continue into early next week. Onshore winds will increase to a fresh (BF 5) breeze by mid week. Rain chances will be low (10-30%) through much of next week.

FIRE WEATHER

Issued at 1143 AM CST Sat Feb 28 2026

Onshore flow will increase the humidity across South Texas. However, fuels remain cured, thus elevated fire weather conditions are possible at times through the weekend into next week, mainly across the Rio Grande Plains where minimum RH values will be in the mid 20s to lower 30s. Winds are expected to remain below thresholds through early next week. However, winds may strengthen to critical levels by the middle of next week, but so do the minimum relative humidity values.
