DISCUSSION
ISSUED AT 1055 PM CDT THU AUG 7 2025
AN UPPER-LEVEL RIDGE TO REMAIN ANCHORED ACROSS TEXAS THROUGH
FRIDAY ALLOWING FOR SUBSIDENT NORTHERLY FLOW TO DRIVE AFTERNOON
HIGH TEMPERATURES INTO THE UPPER 90S TO NEAR 100 DEGREES. AT THE
SURFACE, HIGH PRESSURE TO THE EAST WILL ALLOW FOR WEAK SOUTHERLY
FLOW WHICH WILL CONTRIBUTE TO GRADUALLY INCREASING DEWPOINT
VALUES. THE COMBINATION OF HIGHS NEAR 100 AND DEWPOINT VALUES IN
THE LOWER 70S WILL ALLOW FOR HEAT INDEX VALUES TO EXCEED 105
DEGREES ON FRIDAY AFTERNOON ACROSS EAST AND NORTHEAST TEXAS,
SOUTHEAST OKLAHOMA, AND PORTIONS OF NORTHWEST LOUISIANA AND
SOUTHWEST ARKANSAS. THUS, A HEAT ADVISORY REMAINS IN EFFECT
ACROSS THESE AREAS FOR FRIDAY.
AN INVERTED UPPER-TROUGH EXTENDING FROM THE NORTH-CENTRAL GULF
INTO THE SOUTHEASTERN CONUS WILL RETROGRADE WEST ACROSS THE
ARKLATEX ON SATURDAY. INSTABILITY ASSOCIATED WITH THE TROUGH WILL
ALLOW FOR SLIGHTLY COOLER TEMPERATURES IN THE MID 90S ACROSS
LOUISIANA AND ARKANSAS, WITH HIGHS CONTINUING IN THE UPPER 90S
ACROSS TEXAS AND OKLAHOMA WHICH WILL REMAIN UNDER THE INFLUENCE
OF THE EASTERN PERIPHERY RIDGE. ADDITIONALLY, COULD SEE A FEW
DIURNALLY DRIVEN SHOWERS ACROSS NORTH LOUISIANA ON SATURDAY DUE TO
INSTABILITY ASSOCIATED WITH THE UPPER-LEVEL TROUGH.
THE TROUGH IS FORECAST TO RETROGRADE WEST INTO CENTRAL AND SOUTH
TEXAS, POSSIBLY DEEPENING INTO A CLOSED LOW ON SUNDAY. THE TROUGH
WILL THEN LINGER ACROSS TEXAS THROUGH MOST OF THE WORKWEEK.
INSTABILITY ASSOCIATED WITH THE TROUGH WILL RESULT IN SUFFICIENT
MIXING TO LIMIT AFTERNOON HIGHS TO THE LOW TO MID 90S. OTHERWISE,
SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
EACH DAY NEXT WEEK ACROSS MAINLY DEEP EAST TEXAS INTO NORTH
LOUISIANA AND SOUTH ARKANSAS. /05/
