DISCUSSION
ISSUED AT 1143 AM CDT FRI MAR 27 2026
A WEAK SURFACE LOW IS EXPECTED TO TREK ACROSS CENTRAL TEXAS ON
SATURDAY WHICH WILL BRING A WEAK COLD FRONT TO DEEP SOUTH TEXAS. THE
SURFACE LOW WILL CREATE ENOUGH INSTABILITY THAT OUR REGION COULD SEE
A LOW TO MODERATE (20-40%) CHANCE OF ISOLATED OR SCATTERED SHOWERS
TOMORROW MORNING AND AFTERNOON. DAYTIME HIGHS WILL ALSO COOL INTO
THE LOW 80S TOMORROW, DUE TO A COMBINATION OF THE WEAK FRONT AND
INCREASED CLOUD COVER.
OTHERWISE, THE DOMINANT PATTERN FOR THIS UPCOMING WEEK IS UPPER-
LEVEL RIDGING, WHICH WILL KEEP CONDITIONS WARM AND DRY THROUGHOUT
THE WEEK. TEMPERATURES ARE EXPECTED TO WARM BACK INTO THE UPPER
80S/LOWER 90S AGAIN BY SUNDAY GRADUALLY WARM INTO THE MID-UPPER 90S
BY NEXT FRIDAY. SOME GUIDANCE IS SUGGESTING THAT THE RIDGING
PATTERN COULD BREAK DOWN BY THE END OF THE WEEK AS A PACIFIC
SHORTWAVE APPROACHES FROM THE WEST BY THE END OF THE WEEK, BUT EXACT
IMPACTS ARE UNCERTAIN.
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 1143 AM CDT FRI MAR 27 2026
LOW TO MODERATE WINDS AND SEAS ARE EXPECTED WITH OVERALL FAVORABLE
MARINE CONDITONS. TOMORROW'S COLD FRONT MAY BRING SOME SHOWERS
OFFSHORE, BUT OTHERWISE NO SMALL CRAFT EXERCISE CAUTION OR SMALL
CRAFT ADVISORIES ARE EXPECTED.
