DISCUSSION
(TONIGHT THROUGH NEXT SATURDAY)
ISSUED AT 1155 PM CDT SAT MAY 30 2026
ALOFT, WEAK ZONAL FLOW HAS SLOWLY TRANSITIONED INTO UPPER-LEVEL
RIDGING. AT THE SURFACE, HIGH PRESSURE IN THE WESTERN ATLANTIC
WILL KEEP OUR BACKGROUND WINDS FROM THE SOUTH.
FOR SUNDAY, CONDITIONS WILL BE SUNNY AND MOSTLY DRY, WITH HIGH
TEMPERATURES IN THE 90S. IN THE AFTERNOON, WE SHOULD SEE A FEW
DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS. AS WE MOVE INTO THE
WORK WEEK, AFTERNOON SHOWERS AND THUNDERSTORMS WILL BE MORE
WIDESPREAD ALONG WITH THE ADDITION OF SOME SEABREEZE EFFECTS.
THIS FORECAST WILL REPEAT FOR MOST OF THE WEEK AS WEAK RIDGING
ALOFT WILL KEEP SKIES MOSTLY CLEAR, AND TEMPERATURES WILL SLOWLY
CLIMBAT LEAST FOR THE FIRST HALF OF THE WEEK. WHILE WE ARE NOT
CLOSE TO HEAT ADVISORY LEVELS, WE ARE LOOKING AT APPARENT
TEMPERATURES BREAKING INTO THE TRIPLE DIGITS ACROSS MUCH OF
CENTRAL LOUISIANA AND THE INTERIOR OF SOUTHEAST TEXAS. IF YOU ARE
WORKING OUTSIDE OR STARTING PRACTICE, MAKE SURE TO TAKE PLENTY OF
BREAKS AND STAY HYDRATED!
FOR THE SECOND HALF OF THE WEEK, THE UPPER-LEVEL RIDGE WILL START
TO BREAK, LEADING TO MORE WIDESPREAD CONVECTION AND CLOUD COVER.
THIS WILL LEAD TO TEMPERATURES DROPPING BACK INTO THE UPPER 80S.
WHILE NOT A HUGE RELIEF FROM THE HEAT, WE WILL TAKE ANYTHING WE
CAN AS WE START THE DOG DAYS OF SUMMER.
