DISCUSSION
ISSUED AT 1053 PM CDT FRI AUG 8 2025
THE REGION WILL BE SPLIT BETWEEN AN UPPER-LEVEL RIDGE OF HIGH
PRESSURE ACROSS TEXAS AND OKLAHOMA AND A BROAD UPPER-LOW ACROSS
THE WESTERN GULF INTO LOUISIANA AND MISSISSIPPI ON SATURDAY. AREAS
UNDER THE RIDGE, INCLUDING EAST AND NORTHEAST TEXAS AS WELL AS
SOUTHEAST OKLAHOMA AND ADJACENT COUNTIES IN SOUTHWEST ARKANSAS CAN
EXPECT ANOTHER HOT AND DRY DAY WITH TEMPERATURES IN THE MID TO
UPPER 90S AND HEAT INDEX VALUES EXCEEDING 105 DEGREES. THUS, A
HEAT ADVISORY REMAINS IN EFFECT FOR THESE AREAS THROUGH SATURDAY.
ELSEWHERE, THE INFLUENCE OF THE UPPER-TROUGH WILL ALLOW FOR ENOUGH
INSTABILITY AND MIXING TO RESTRICT HIGH TEMPERATURES TO THE MID
90S WITH HEAT INDEX VALUES REMAINING BELOW ADVISORY CRITERIA.
THE UPPER-TROUGH WILL RETROGRADE WEST INTO TEXAS ON SUNDAY
BRINGING A SLIGHTLY UNSETTLED WEATHER PATTERN ACROSS THE ARKLATEX THROUGH
MIDWEEK. AFTERNOON SHOWERS AND THUNDERSTORMS CAN BE EXPECTED EACH
DAY WITH THE HIGHEST RAIN CHANCES EXPECTED ON MONDAY. BY MIDWEEK,
THE PATTERN WILL HAVE CHANGED VERY LITTLE WITH THE UPPER-TROUGH
LINGERING ACROSS CENTRAL TEXAS INTO OKLAHOMA AND A RIDGE BUILDING
ACROSS THE NORTHERN GULF COAST. WITH THE BUILDING RIDGE,
TEMPERATURES ACROSS MAINLY NORTH LOUISIANA AND SOUTH ARKANSAS
COULD AGAIN APPROACH THE UPPER 90S ON THURSDAY AND FRIDAY. /05/
