UPDATE

Issued at 622 PM CST Thu Dec 11 2025

Latest hi-res guidance continues to show a foggy night in store for much of South Texas tonight. For this reason, a Dense Fog Advisory has been issued from midnight tonight through 10 am CST Friday. Locations in Webb and La Salle Counties may see reductions in visibility a bit later than the other counties (most likely by 3 AM CST Friday).

KEY MESSAGES

Updated at 622 PM CST Thu Dec 11 2025

- Gradual warm-up through the weekend ahead of the next cold front on Sunday.

- Patchy to areas of fog possible inland and across the coastal waters beginning tonight and continuing through the weekend.

- Low to medium chance for rain this weekend ahead of Sunday cold front.

DISCUSSION

Issued at 1139 AM CST Thu Dec 11 2025

The reinforcing surge of high pressure behind yesterday's weak front will shift eastward this evening, allowing for low-level winds to turn onshore. This will initiate WWA and cause temperatures to begin a steady climb through the weekend. Expect highs in the upper 70s to low 80s and lows in the 50s to low 60s.

Moisture will generally remain limited through the end of the work week, resulting in very low rain chances across the region. However, the return of south-southeasterly flow will support a gradual increase in boundary layer moisture beginning tonight. This will introduce the potential for fog during the overnight and early morning hours through the weekend. If light winds and relatively cool shelf waters persist, sea fog will also be a strong possibility over the bays and nearshore waters. This is particularly the case for Saturday night into early Sunday when moisture pooling and weaker winds ahead of our next cold front favor more widespread formation.

Speaking of our next cold front, confidence continues to improve regarding its timing for Sunday and its strength, with temperatures trending below average for Sunday night and Monday. Increasing moisture ahead of the front will allow for low to medium (20-60%) rain chances to return Sunday along the frontal passage.

Onshore flow is expected to reestablish itself early next week, as the surface high behind the front propagates east, leading once again to an increase in temperatures and moisture advection as well as low rain chances (~20%) along the coast by Tuesday.

AVIATION

(00Z TAFS) Issued at 522 PM CST Thu Dec 11 2025

VFR conditions are expected this evening before dropping to MVFR and IFR/LIFR overnight before recovering back to VFR late tomorrow morning. The probability for fog to develop tonight is high, with most sites likely to see dense fog. While chances for fog are high, the timing of the onset and dissipation are still a little foggy. The best chances for dense fog will be across the eastern sites. As the sun rises tomorrow morning, the fog will gradually dissipate. Winds will be light throughout this TAF cycle.

MARINE

Issued at 1139 AM CST Thu Dec 11 2025

Gentle to moderate northeasterly winds (BF 3-4) will shift to the south-southeast tonight and continue through Saturday night. With onshore flow resulting in elevated moisture, sea fog potential increases as we head into the weekend with the best chances of fog being during the overnight and morning hours. Rain chances remain next to none through the remainder of the workweek before a low to medium chance (20-60%) of rain returns this weekend ahead of our next frontal passage. In the wake of our next front on Sunday, winds will shift to the northeast and strengthen to become fresh to strong (BF 5-6). This wind setup will persist through Monday morning before settling back down to gentle to moderate levels (BF 3-4) and once again shifting into an onshore flow pattern.

FIRE WEATHER

Issued at 1139 AM CST Thu Dec 11 2025

Minimum relative humidity values will remain above 30% through next week. Southeasterly winds will be weak through much of this weekend before our next frontal passage on Sunday results in elevated north-northeasterly winds of 10-15 mph and gusts up to 25-30 mph. However, with increased moisture from our southeasterly winds, low to medium chances for rain ahead of the front, and ERCs generally remaining in the 25-50th percentile, elevated fire weather conditions remain negligible at this time.
