DISCUSSION

Issued at 1109 AM CST Thu Dec 18 2025

Areas of dense fog this morning have finally lifted though cloudy skies linger. Expect a cold front will move across the area this afternoon/evening which will bring in much drier air. This will also serve to drop our temperatures from the 70s and 80s this afternoon into the 60s and 70s for Friday (near normal). Unfortunately, these cooler temperatures will not last, with highs rebounding into the 80s by the weekend. These will last through at least Christmas Day with near-zero chances for rain.

AVIATION

(18Z TAFS) Issued at 1109 AM CST Thu Dec 18 2025

Conditions will continue to improve into this afternoon, with VFR conditions expected by 18Z-19Z. A cold front will move through the area this afternoon and evening which will usher in drier air. Confidence is low, but low level wind shear is possible tonight and into early Friday morning, mainly for CRP and VCT. Have not included this in the TAF but this is certainly something we will need to monitor. VFR conditions are expected to persist through the rest of the TAF period. There is low to moderate confidence in brief MVFR/IFR visibility from 09Z-12Z Friday morning, but this will be highly dependent on how dry the lower levels get behind the cold front.

MARINE

Issued at 1109 AM CST Thu Dec 18 2025

Gentle to moderate (BF 3-4) surface winds today will switch from southwesterly to northeasterly winds with a cold front passage. Winds behind the front will increase to 20-30 kts between midnight to 6am Friday (seas increasing to 5-7 ft) with conditions decreasing through the remainder of Friday. A Small Craft Advisory is in effect from 10 PM this evening to 9 AM Friday. Gentle to moderate onshore flow returns by Saturday morning with 2-3 ft seas through the end of the forecast period.

FIRE WEATHER

Issued at 1210 AM CST Thu Dec 18 2025

The cold front is still in store to move through South Texas this afternoon, dropping dewpoint temperatures. RH values will briefly drop as low as 25-35% across the Rio Grande Plains/Brush Country, but weak winds will limit the fire risk. More of that drier air settles in across the northern Brush Country with similar low min RHs in store Friday afternoon. Starting Saturday, min RH values will remain above 30% region wide with warm temps and near-zero rain chances.
