DISCUSSION

Issued at 1205 PM CST Sat Jan 10 2026

The much anticipated cold front made its way across Deep South Texas prior to daybreak this morning, ushering in a notably cooler and drier airmass. Persistent cold air advection will maintain temperatures mostly in the 60s over the next few hours, before falling into the upper 50s later this afternoon and evening. Most areas will fall into the upper 40s by early Sunday morning, with the exception being along the immediate coast and the Low/Mid RGV where low temperatures will fall into the low 50s.

Breezy northerly to northwesterly winds around 20-25 MPH with gusts up to 35 MPH will continue through this evening, before falling slightly tonight. Wind gusts ranging from 20-25 MPH are likely to continue through Sunday evening, but should slacken by Sunday evening as high pressure settles in. Elevated fire weather concerns will continue into Sunday as winds remain breezy and low humidity remains in place across the region. Additionally, adverse beach conditions will continue through the weekend as winds and seas remain elevated in wake of the cold front. A high risk of rip currents remains in place along the Lower Texas beaches. Minor coastal flooding cannot be ruled out, especially near high tide and along narrow beaches this weekend.

Temperatures will run around 5-10 degrees below normal through Tuesday, and near normal Wednesday through the end of the week. Guidance indicates there may be another cold front that arrives mid to late week, which will likely result in elevated fire weather concerns due to the combination of breezy winds and low humidity.

AVIATION

(18Z TAFS) Issued at 1205 PM CST Sat Jan 10 2026

BKN to OVC cloud cover will prevail through the forecast period, but should remain VFR with ceilings above 5,000-8,000 feet. Otherwise, expect breezy northerly to northwesterly winds to persist, with gusts up to 32 knots through this evening and gusts around 20-25 knots through tomorrow.

MARINE

Issued at 1205 PM CST Sat Jan 10 2026

Adverse marine conditions return late tonight into early tomorrow morning in wake of the passage of a cold front. A Small Craft Advisory will continue through at least Sunday morning as seas and northerly winds increase in wake of the cold front, and will likely need to be extended through at least Sunday evening as winds and seas remain elevated. Near gale force wind gusts cannot be ruled out this afternoon. Conditions should become more favorable by early next week.
