DISCUSSION
ISSUED AT 159 PM CDT TUE JUN 9 2026
ANOTHER WARM AND HUMID DAY, AS UPPER RIDGING HAS SETTLED INTO THE
REGION. THIS PROMPTED US TO ISSUE A HEAT ADVISORY FOR SOUTHEAST
OKLAHOMA, AND PORTIONS OF NORTHEAST TEXAS AND ADJACENT SOUTHWEST
ARKANSAS, AS HEAT INDEX VALUES ARE FORECASTED TO REACH THE 105
DEGREE THRESHOLD. DESPITE THE RIDGE IN PLACE, A STRAY SHOWER OR
THUNDERSTORM CAN'T BE RULED OUT WITH PEAK HEATING THIS AFTERNOON,
ESPECIALLY ACROSS OUR DEEP EAST TEXAS AND ADJACENT CENTRAL
LOUISIANA ZONES. CURRENTLY, WE ARE SEEING SOME ISOLATED SEABREEZE
INDUCED CONVECTION ACROSS SOUTHEAST TEXAS AND ADJACENT SOUTHWEST
LOUISIANA NEAR THE I-10 CORRIDOR, WHICH IS PUSHING NORTHWARD. IF
THIS ACTIVITY MAKES IT INTO OUR REGION, IT WILL LIKELY DISSIPATE
AROUND SUNSET DUE TO THE LOSS OF DAYTIME HEATING. EXPECT SIMILAR
CONDITIONS OVER THE NEXT COUPLE OF DAYS, AS UPPER RIDGING WILL
REMAIN IN PLACE OVER THE REGION. AFTERNOON HIGHS WILL CONTINUE TO
CLIMB INTO THE LOW TO MID 90S. WE CAN'T RULE OUT ADDITIONAL HEAT
ADVISORIES, AS AFTERNOON HEAT INDICES WILL LIKELY RANGE BETWEEN
100-106 DEGREES DURING THIS PERIOD. WE COULD ALSO SEE MORE STRAY
TO ISOLATED SHOWERS WITH DAYTIME HEATING, ESPECIALLY ON WEDNESDAY
ACROSS OUR DEEP EAST TEXAS AND ADJACENT CENTRAL LOUISIANA ZONES.
BY THURSDAY NIGHT, THE SYNOPTIC WEATHER PATTER WILL START TO
CHANGE, AS THE AFOREMENTIONED UPPER RIDGE WILL START TO FLATTEN
OUT. THIS WILL ALLOW A LONG-WAVE TROUGH TO DIVE SOUTHWARD INTO
THE REGION BY FRIDAY MORNING. AT THE MOMENT, LONG-TERM PROGS HALT
THE SOUTHWARD PROGRESSION OF THE TROUGH TO THE NORTHERN HALF OF
OUR FORECAST AREA THROUGH SATURDAY. THIS WILL LIKELY KEEP THE BEST
RAIN CHANCES ALONG AND NORTH OF THE I-20 CORRIDOR THROUGH THE
FIRST HALF OF THE WEEKEND. BY SUNDAY, WHAT'S LEFT OF THE RIDGE
WILL START TO SHIFT WESTWARD INTO THE SOUTHWEST CONUS. FLOW ALOFT
WILL BECOME MORE NORTHWESTERLY, DRIVING A COOL FRONT INTO THE
REGION LATE SUNDAY INTO EARLY MONDAY MORNING. THIS WILL BRING
WIDESPREAD RAIN CHANCES ACROSS THE REGION. PREVIOUS MODEL RUNS HAD
THE FRONT STALLING ACROSS THE AREA, KEEPING RAIN CHANCES IN THE
FORECAST FOR TUESDAY. HOWEVER, THE MOST RECENT RUNS ARE SUGGESTING
THE FRONT WILL PUSH THROUGH THE REGION. THIS WOULD BRING A RETURN
OF DRY WEATHER, ALONG WITH SLIGHTLY COOLER AND LESS HUMID CONDITIONS.
