DISCUSSION

Issued at 1212 PM CST Sun Jan 4 2026

No significant changes in the forecast from the last package. Return of light onshore flow under mostly clear skies will be conducive for fog and low clouds over inland areas of South Texas tonight. Latest HREF keeps low chances (20-40%) of fog less than a mile visibility over inland Coastal Plains and Brush Country, with greater chances northward into the Hill Country. Confidence is not as high as I was yesterday.

Warm onshore flow with a mid-level ridge over the Gulf will keep rain-free and above normal temperatures intact through Thursday, before our next cold front pushes through Friday or early Saturday. We'll need to keep a close eye on our sea fog potential as current shallow SSTs hover from the mid to upper 60s interact with dewpoints in the upper 60s through midweek. Very low (10-20%) rain chances will accompany the front next weekend with highs dropping into the 60s and lows in the 40s.

AVIATION

(00Z TAFS) Issued at 545 PM CST Sun Jan 4 2026

VFR conditions will prevail through the evening hours. Clouds and fog are expected to develop across S TX after 06Z leading to prevailing MVFR/IFR conditions with brief periods of LIFR between 10-16Z Monday morning. There is some uncertainty as to how low visibilities will get to as some models show dense fog more widespread mainly across the Hill Country with S TX more patchy with higher VSBYs. Other models indicate densest fog (1/4-1/2SM) around the ALI site early Monday morning while the other S TX TAF sites VSBYs remain at or above 1SM. The surface winds will be light, but just above the surface, winds are expected to increase to around 20 knots which may lead more to low stratus rather than fog. Could see a scenario where IFR/LIFR conditions develop after 06Z, but improve to MVFR/IFR once winds above the surface strengthen after 08-10Z. Thus, leading to the low confidence of fog potential. VFR conditions expected to resume by mid to late Monday morning.

MARINE

Issued at 1212 PM CST Sun Jan 4 2026

A gentle (BF 3) easterly breeze has developed today and will shift south to southeasterly and strengthen to a moderate (BF 4) flow tonight, continuing through Tuesday night. Winds strengthen to a fresh to strong (BF 5-6) onshore flow by mid week before a cold front pushes through late in the week into next weekend, shifting winds out of the north to northeast. Areas of sea fog will be possible daily through the period as dewpoints climb to the upper 60s and shallow water temperatures remain slightly cooler in the mid to upper 60s. Low (20-30%) rain chances return Friday and will continue through the weekend.

FIRE WEATHER

Issued at 1212 PM CST Sun Jan 4 2026

Relative humidity will remain above 30% through Thursday before our next cold front pushes through Friday or Saturday, leading to a drier period with RH values ranging as low as 15-30% next weekend during the afternoon. Low rain chances return next weekend. However, winds will likely remain light. Elevated fire weather concerns are not anticipated at this time.
