DISCUSSION
ISSUED AT 1130 AM CST TUE JAN 6 2026
ANOTHER ROUND OF FOG DEVELOPMENT IS EXPECTED LATE TONIGHT INTO
TOMORROW MORNING DUE TO THE COMBINATION OF FAVORABLE LOW LEVEL
MOISTURE CONTENT AND GENERALLY LIGHT WINDS. MOST HIGH RES GUIDANCE
INDICATES THE BEST POTENTIAL FOR DENSE FOG WILL REMAIN NORTH OF
THE REGION, BUT VISIBILITY FALLING BELOW 3SM CANNOT BE RULED OUT
ACROSS PORTIONS OF THE REGION. ANY FOG SHOULD DISSIPATE BY MID
MORNING TOMORROW. FAVORABLE CONDITIONS FOR FOG DEVELOPMENT WILL
LIKELY CONTINUE EACH MORNING OVER THE NEXT FEW DAYS, ALTHOUGH
INCREASING WINDS MAY LIMIT THIS POTENTIAL TOWARDS THE END OF THE
WEEK.
OTHERWISE, ABOVE NORMAL TEMPERATURES AND RAIN-FREE CONDITIONS WILL
CONTINUE THROUGH THE END OF THE WEEK ACROSS ALL OF DEEP SOUTH
TEXAS. BREEZY SOUTHERLY TO SOUTHEASTERLY WINDS RETURN BY MID TO
LATE WEEK IN RESPONSE TO A TIGHTENING PRESSURE GRADIENT AHEAD OF A
DEEPENING UPPER LEVEL SYSTEM TRANSLATING ACROSS THE PLAINS. THIS
SYSTEM WILL SEND A COLD FRONT TOWARDS THE REGION BY THE END OF THE
WEEK, WHICH WILL BRING MORE SEASONABLE TEMPERATURES HEADING INTO
THE WEEKEND. LOW RAIN CHANCES MAY RETURN OVER THE WEEKEND, BUT
CHANCES REMAIN AROUND 20 PERCENT.

SOUTHEAST WINDS THROUGH THE FORECAST PERIOD WITH SPEEDS GENERALLY
BELOW 10 KNOTS.
MARINE
ISSUED AT 1130 AM CST TUE JAN 6 2026
GENERALLY FAVORABLE MARINE CONDITIONS WILL PREVAIL THROUGH MID
WEEK OVER THE GULF WATERS AND LAGUNA MADRE WITH GENERALLY LOW SEAS
AND LIGHT TO MODERATE SOUTHERLY WINDS. SMALL CRAFT EXERCISE

TIGHTENING PRESSURE GRADIENT. BRIEF SMALL CRAFT ADVISORY
