DISCUSSION
ISSUED AT 1010 PM CDT FRI MAR 27 2026
A COLD FRONT IS CURRENTLY POSITIONED ALONG A HOUSTON TO LAREDO
LINE. THE PASSAGE OF THIS FRONT WILL PRODUCE SCATTERED SHOWERS
WITH NEAR NORMAL HIGH TEMPERATURES FOR DEEP SOUTH TEXAS AND THE
RIO GRANDE VALLEY ON SATURDAY. TEMPERATURES WILL THEN BEGIN TO
WARM ON SUNDAY AS ISOLATED TO SCATTERED CONVECTION REMAINS A
POSSIBILITY. HOWEVER, FOR THE REMAINDER OF THE FORECAST PERIOD,
WELL ABOVE NORMAL TEMPERATURES WITH GENERALLY DRY WEATHER WILL
PREVAIL WITH 500 MB HIGH PRESSURE GRADUALLY NOSING IN FROM THE
WEST.
LONG RANGE MODEL GUIDANCE SUGGESTS THAT WINDS MAY BE STRONG ENOUGH
NEXT FRIDAY TO WARRANT A WIND ADVISORY FOR THE EASTERN PORTION OF
THE BRO CWFA. IN FACT, A BREEZY TO WINDY ONSHORE FLOW FROM SUNDAY
THROUGH FRIDAY MAY POSE A RISK FOR ENHANCED WILDFIRE GROWTH AND
SPREAD, THE RESULT OF WHICH MAY BE THE NEED FOR RANGELAND FIRE
DANGER STATEMENTS DURING SOME OR ALL OF THESE DAYS.
OF COURSE, WITH INTENSIFYING WINDS AND BUILDING SEAS ALONG THE
LOWER TEXAS COAST, A MODERATE TO HIGH RISK OF RIP CURRENTS MAY
RESULT AT THE LOCAL BEACHES.
AVIATION
(00Z TAFS)
ISSUED AT 628 PM CDT FRI MAR 27 2026
THE PASSAGE OF A COLD FRONT IS ANTICIPATED DURING THE OVERNIGHT
HOURS TONIGHT. THE PROB30 FOR PRECIPITATION HAS BEEN REMOVED FROM
THE PREVIOUS SUITE OF TAFS, AS RAIN CHANCES FOR SATURDAY APPEAR A
BIT LOWER NOW. STILL, ISOLATED CONVECTION CANNOT BE ENTIRELY RULED
OUT. OVERALL, VFR WILL PREVAIL THROUGH THE NEXT 24 HOURS.
MARINE
ISSUED AT 1010 PM CDT FRI MAR 27 2026
DESPITE THE PASSAGE OF A WEAK COLD FRONT DURING THE PRE-DAWN HOURS
OF SATURDAY, FAVORABLE MARINE CONDITIONS ARE FORECAST ALONG THE
LOWER TEXAS COAST DURING THE WEEKEND. AN INTENSIFYING PRESSURE
GRADIENT OVER THE WESTERN GULF OF AMERICA WILL PRODUCE STRONGER
WINDS AND HIGHER SEAS FOR THE NEW WORK WEEK, RESULTING IN SMALL
CRAFT SHOULD EXERCISE CAUTION AT A MINIMUM AND POSSIBLE SMALL
CRAFT ADVISORY TOWARDS THE MIDDLE AND END OF THE WEEK.
