ISSUED AT 1210 AM CST MON JAN 5 2026
WITH THE RETURN OF SOUTHERLY FLOW TO THE LOCAL AREA, FOG AND LOW
CLOUD DEVELOPMENT IS IN STORE FOR THE OVERNIGHT PERIOD INTO MONDAY
MORNING. SOME MODELS BRING VISIBILITY DOWN TO A MILE OR LESS AND
OTHERS DON'T. THEREFORE, ONCE WE START GETTING OBSERVATIONS AND LOW
VISIBILITY VALUES THAT MEET DENSE FOG ADVISORY CRITERIA, THEN WE
ISSUE IT. OTHERWISE, FOG AND LOW CLOUDS LIFT LATE MORNING/EARLY
AFTERNOON FOR PARTLY CLOUDY SKIES. HIGHS ARE FORECAST TO RANGE FROM
THE LOWER TO MID 70S MOST LOCATIONS TO UPPER 70S ACROSS THE COASTAL
PLAINS. MAY BE BREEZY ACROSS THE HILL COUNTRY MID AFTERNOON,
OTHERWISE, WIND SPEEDS OF 10 MPH OR LESS ARE FORECAST FOR THE LOCAL
AREA.
THE NIGHT TIME COMES AND THE PATTERN REPEATS WITH FOG AND LOW CLOUDS
DEVELOPING OVERNIGHT AND BREAKING BY MIDDAY. IN THE MEANTIME, A
SURFACE TROUGH/DRY-LINE PUSHES FROM THE SOUTHERN EDWARDS PLATEAU
INTO THE I-35 CORRIDOR TO BRING TEMPERATURES INTO THE LOWER AND MID
80S. IT IS GOING TO BE VERY WARM FOR THIS TIME OF THE YEAR AND SOME
DAILY HIGH TEMPERATURE RECORDS COULD BE BROKEN. CLOUDS RETURNS AT
NIGHT AND LOWS GET DOWN TO THE 50S AREAWIDE.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 1210 AM CST MON JAN 5 2026
ANOTHER WARM DAY IS FORECAST FOR WEDNESDAY WITH HIGHS IN THE LOWER
80S FOR MOST AREAS. LATER IN THE EVENING INTO THE OVERNIGHT HOURS, A
PIECE OF ENERGY FROM AN UPPER LEVEL DISTURBANCE MOVING ACROSS
NORTHERN MEXICO AND ARIZONA MAY BRING ENOUGH INSTABILITY TO PORTIONS
OF THE RIO GRANDE AND SOUTHERN EDWARDS PLATEAU TO PRODUCE SOME
SHOWERS THERE. OTHERWISE, MODELS ARE TRENDING DRIER FOR MOST OF
THURSDAY INTO EARLY FRIDAY.
A COLD FRONT IS FORECAST TO PUSH ACROSS SOUTH CENTRAL TEXAS DURING
THE DAY ON FRIDAY TO COOL TEMPERATURES DOWN AND PROVIDES A SLIGHT
CHANCE FOR SHOWERS MAINLY FOR AREAS ALONG AND EAST OF HIGHWAY 77.
FRIDAY'S HIGHS ARE FORECAST TO RANGE FROM THE MID TO UPPER 60S
ACROSS THE HILL COUNTRY TO UPPER 70S ACROSS THE COASTAL PLAINS.
OVERNIGHT LOWS TO DROP TO THE MID TO UPPER 30S FOR THE HILL COUNTRY
TO MID 40S ELSEWHERE.
NEXT WEEKEND LOOKS DRY AND COOLER WITH TEMPERATURES CLOSER TO
CLIMATE NORMALS WITH HIGHS IN THE 60S AND LOWS IN THE LOWER TO UPPER
30S WITH A NEW SURGE OF A COOLER AIRMASS PUSHING INTO THE LOCAL
AREA.
