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. /05/

FOR THE 27/12Z TAF PACKAGE...IT APPEARS THAT ALL OUR TERMINALS ARE
THROUGH WITH PRECIPITATION, AT LEAST THROUGH THIS MORNING BUT DID
HOLD ONTO VCSH FOR A FEW MORE HOURS AT THE LFK TERMINAL. WE ARE
SEEING DEVELOPING IFR CEILINGS IN THE WAKE OF THE LARGE RAIN
SHIELD THAT MOVED THROUGH S AR AND N LA OVERNIGHT LAST NIGHT AND
FOR THIS REASON, WILL HAVE TO PREVAIL IFR CEILINGS AT THE TXK,
ELD, SHV AND MLU TERMINALS THROUGH MID MORNING TODAY BEFORE THESE
CEILINGS SCATTERS OUT. THUS VFR CONDITIONS WILL RETURN TO ALL
TERMINALS BY MID TO LATE MORNING AND CONTINUE THROUGH THE DAY AND
INTO THE EVENING. DID NOT INCLUDE THIS IN THE 12Z TAF PACKAGE BUT
WOULD NOT BE SURPRISED TO SEE SOME PATCHY FOG FORM OVERNIGHT
TOWARDS THE TAIL END OF THIS 24HR PACKAGE. LOOK FOR MOSTLY
NORTHEAST WINDS TODAY WITH SPEEDS GENERALLY UNDER 10KTS, BECOMING
LIGHT TO NEAR CALM OVERNIGHT.
