DISCUSSION

Issued at 1218 PM CST Wed Dec 24 2025

Santa is in for a tricky ride this year, as dense fog rolls in again over South Texas this Christmas Eve. Rudolph's nose will be working overtime cutting through the thick mist. Here at the National Weather Service we will aid Santa by keeping a close eye on conditions via satellite and radar, helping guide the sleigh safely through the fog. It won't be the clearest ride, but with Rudolph leading the way, Christmas magic will arrive right on time!

Early risers along the immediate coast on Christmas day may see a few streamer showers drifting in from the Gulf, while inland it will be warm and muggy. Conditions are forecast to improve around mid to late morning with the fog lifting, while the rest of Christmas Day will be very warm with highs in the 80s.

Warm and humid conditions with nightly rounds of patchy to areas of fog will continue into the weekend, before the arrival of our next cold front Sunday night. This next boundary will bring much cooler temperatures, breezy northerly winds, and low to medium rain chances (20-40%) Sunday night into Monday. Latest guidance indicates a brief period of Wind Advisory conditions developing along the immediate coast Monday morning, while the fire weather risk could become elevated by the afternoon as humidity levels drop below 30% inland. By Tuesday night into Wednesday morning, a few locations over the Victoria Crossroads could fall to near freeze. We will continue to monitor the latest trends and adjust the forecast over the coming days to better highlight these hazards and issue products accordingly. Stay tuned.

AVIATION

(00Z TAFS) Issued at 508 PM CST Wed Dec 24 2025

VFR will prevail through the evening hours before conditions deteriorate once again overnight to IFR/LIFR levels due to another round of patchy to areas of dense fog. Although the fog is expected to erode by 15-16Z on Christmas Day, ceilings will be slower to lift. Therefore, have maintained eastern sites at MVFR/IFR levels through the end of the cycle. Winds will be light and variable through the period.

MARINE

Issued at 1218 PM CST Wed Dec 24 2025

A Marine Dense Fog Advisory remains in effect through 3 PM today over the nearshore waters and northern bays. Additional rounds of patchy to areas of fog can be expected nightly through Saturday. Otherwise, a generally gentle to moderate (BF 3-4) onshore flow will persist through late in the week. A cold front Sunday morning will result in winds being more out of the northeast at a strong to gale strength (BF 6-7) with seas building to 5-8 ft by Monday. Aside from some streamer showers on Thursday (10-15% chance of rain), the next best chance comes with the cold front, though confidence is low on exact chances.

FIRE WEATHER

Issued at 1218 PM CST Wed Dec 24 2025

Light winds, relative humidity values remaining above 40%, and Energy Release Components in the 25-49th percentile will keep the fire risk limited into the weekend. A cold front is forecast to move through Sunday night with min RH values falling below 30% daily Monday through Wednesday. Breezy conditions on Monday could result in elevated fire weather concerns. Low end rain chances Sunday night into Monday morning will be scattered in coverage (20-40% chances).
