KEY MESSAGES

Updated at 541 AM CST Thu Dec 4 2025

- Low to medium rain chances (20-50%) today through Friday

- Potential minor coastal flooding today through late week

DISCUSSION

Issued at 1209 AM CST Thu Dec 4 2025

Patchy light rain, drizzle, and fog continues overnight across the region courtesy of a passing coastal trough and an overrunning pattern that developed ahead of the next frontal boundary. Moisture will linger through the morning hours today allowing for additional low to medium (20-50%) rain chances over the area. The front is progged to push through during the afternoon hours today, with slightly drier conditions expected behind it through the evening. By Friday though, rain chances increase again (20-50%) especially over portions of the Victoria Crossroads where isentropic lift becomes more efficient. After that, the weekend is shaping much drier, while another boundary is progged to swing through the region on Sunday. Generally dry conditions will then follow into next week as high pressure settles over the area.

Temperatures today will run a few degrees cooler than yesterday, with highs in the upper 50s to mid 60s. Tonight, lows will drop into the 40s again areawide in the wake of the front, while highs will struggle to get out of the 50s on Friday. Much warmer temperatures can then be expected over the weekend (highs in the upper 60s to low 80s), followed by slightly cooler temperatures early next week behind the secondary front.

Minor coastal flooding remains a concern through late week. Tides on Wednesday reached 1.8 ft MSL at high tide, but swell periods remained at around 6 seconds which didn't result in impact across area beaches. Today, tides will peak at around 1.8-2.9 ft MSL again, so will keep monitoring beach conditions in case an Advisory is required.

AVIATION

(12Z TAFS) Issued at 541 AM CST Thu Dec 4 2025

LIFR conditions continue across South Texas, both dense fog over the Coastal Bend and widespread 200-400 ft ceilings. A front will push southward across the area this morning, extending south of all terminals by 18Z. I do expect conditions to improve to IFR/MVFR behind the front, greater chances of improving to VFR tonight over COT/LRD. Winds will shift northerly and strengthen to around 15 knots with gusts 20-25 knots in the wake of the front. IFR/MVFR ceilings will continue to hug the Coastal Plains through tonight. Splotches of light rain are currently developing over the region and will continue until the front pushes through, then redevelop near the end of the forecast.

MARINE

Issued at 1209 AM CST Thu Dec 4 2025

A Dense Fog Advisory is in effect for the bays and nearshore waters through 6 AM today. A cold front is forecast to push through the area this afternoon, bringing another wave of fresh to strong northerly flow in its wake through Friday morning. This will result in Small Craft Advisory this afternoon through late tonight. Winds are forecast to weaken to gentle to moderate heading into the weekend, with the wind direction varying. Rain chances today will increase to medium to high, 60-90% through Friday night. Low to medium chances linger through Saturday evening.

FIRE WEATHER

Issued at 1209 AM CST Thu Dec 4 2025

Elevated fire weather conditions are not expected through the week. Winds will remain light to moderate inland, predominately out of the north to northeast. Minimum relative humidity will remain above 30% daily through Saturday. Sunday's relative humidity values will dip below 30% due to a passing cold front, however due to low ERC and winds, confidence is low for any elevated fire weather conditions. Low to medium rain chances continue today through Friday, with greatest chances over the Coastal Bend and Victoria Crossroads.
