DISCUSSION
ISSUED AT 1115 PM CDT SAT AUG 9 2025
AN INVERTED UPPER-LEVEL TROUGH EXTENDING ACROSS THE NORTHWESTERN
GULF INTO THE ARKLATEX AND THE MID-MISSISSIPPI RIVER VALLEY TO
BRING BIG CHANGES TO THE FORECAST THROUGH THE REMAINDER OF THE
WEEKEND INTO MOST OF NEXT WEEK. INSTABILITY ASSOCIATED WITH THE
UPPER-TROUGH WILL ALLOW FOR SUFFICIENT MIXING TO LIMIT HIGH
TEMPERATURES TO THE LOW TO MID 90S THROUGH TUESDAY. HOWEVER, WITH
LOW-LEVEL SOUTHERLY FLOW ACROSS THE ARKLATEX RESULTING FROM A
SURFACE HIGH ACROSS THE APPALACHIANS, DEWPOINT VALUES IN THE MID
70S WILL CONTINUE TO SUPPORT AFTERNOON HEAT INDEX VALUES AROUND
100 TO 105 DEGREES EACH DAY.
THE UPPER-TROUGH WILL LINGER ACROSS TEXAS INTO OKLAHOMA THROUGH
THE MAJORITY OF THE FORECAST PERIOD ALLOWING FOR INCREASED CHANCES
FOR DIURNALLY DRIVEN AFTERNOON CONVECTION EACH DAY ACROSS MAINLY
THE EASTERN HALF OF THE ARKLATEX WITH THE HIGHEST CHANCES ON
MONDAY.
THE UPPER-TROUGH TO EJECT EAST ON WEDNESDAY NIGHT INTO THURSDAY TO
BE REPLACED BY A WESTWARD BUILDING UPPER-RIDGE WHICH WILL BRING A
RETURN OF HOT AND DRY CONDITIONS ACROSS THE REGION LATE IN THE
WORKWEEK WITH TEMPERATURES BY FRIDAY POSSIBLY APPROACHING 100
DEGREES ACROSS PORTIONS OF NORTH LOUISIANA AND SOUTH-CENTRAL
ARKANSAS. /05/
