SURFACE HIGH PRESSURE CENTERED ACROSS THE GREAT LAKES INTO THE
MID-MISSISSIPPI RIVER VALLEY WILL BRING LIGHT NORTHEAST WINDS,
DRIER DEWPOINTS, AND SLIGHTLY COOLER TEMPERATURES TO THE ARKLATEX
OVER THE NEXT COUPLE OF DAYS. A FEW SHOWERS AND ISOLATED
THUNDERSTORMS MAY BE POSSIBLE THIS AFTERNOON ALONG A WEAK SURFACE
BOUNDARY ACROSS DEEP EAST TEXAS INTO WEST CENTRAL LOUISIANA.
SOUTHEAST WINDS TO RETURN LATE IN THE WEEKEND ALLOWING FOR
INCREASED RELATIVE HUMIDITY VALUES ACROSS THE REGION ALONG WITH
TEMPERATURES CLIMBING BACK UP TO NEAR TRIPLE DIGITS ACROSS MAINLY
EAST AND NORTHEAST TEXAS BY SUNDAY.
UPPER-LEVEL RIDGE ACROSS THE FOUR CORNERS REGION TO BUILD EAST ON
SUNDAY. HOWEVER, A WESTWARD MOVING INVERTED UPPER-TROUGH ACROSS
THE NORTHERN GULF WILL FOR NUDGE THE HIGH NORTH OF THE REGION INTO
THE MIDWEST BEFORE WEDGING IT EASTWARD INTO THE APPALACHIANS BY
MONDAY MORNING. UNDER THE INFLUENCE OF THE UPPER TROUGH, COULD
SEE ENHANCED SEABREEZE CONVECTION SOUTH OF I-20 EACH DAY THROUGH
THE END OF THE FORECAST PERIOD ON WEDNESDAY ALONG WITH SEASONAL
HIGH TEMPERATURES IN THE MID 90S.

(00Z TAFS)
ISSUED AT 759 PM CDT THU AUG 27 2026
FOR THE 28/00Z TAF PERIOD, ISOLATED CONVECTION FROM THIS AFTERNOON
HAS LARGELY DIMINISHED AS VFR CONDITIONS PREVAIL THIS EVENING UNDER
MOSTLY SKC WITH JUST SOME PASSING CIRRUS. WILL BE WATCHING FOR THE
DEVELOPMENT OF PATCHY FOG CLOSER TO DAYBREAK AS RECENT RAINFALL AT
MOST SITES AND NEAR CALM WINDS WILL CREATE A CONDUCIVE ENVIRONMENT
FOR FOG FORMATION AS TEMPERATURES FALL NEAR THE DEW POINT BY EARLY
FRIDAY MORNING. THEREFORE, HAVE INCLUDED TEMPO MVFR VSBYS AT MOST
TERMINALS FOR A FEW HOURS AROUND SUNRISE WITH IMPROVING CONDITIONS
THEREAFTER. OTHERWISE, LIGHT/VARIABLE TO NEAR CALM WINDS OVERNIGHT
WILL INCREASE SLIGHTLY FROM THE NE ON FRIDAY BETWEEN 5-10 KTS.
