DISCUSSION
ISSUED AT 1134 PM CDT WED AUG 6 2025
UPPER-LEVEL RIDGE CENTERED ACROSS THE TEXAS PANHANDLE TO CONTINUE
TO PROVIDE SUBSIDENT NORTHERLY FLOW ACROSS THE ARKLATEX ON
THURSDAY. UNDER THIS PATTERN, DRY CONDITIONS TO PREVAIL WITH
AFTERNOON HIGH TEMPERATURES TO CLIMB INTO THE MID TO UPPER 90S.
AT THE SURFACE, A RIDGE OF HIGH PRESSURE EXTENDING ACROSS THE OHIO
AND MISSISSIPPI RIVER VALLEYS INTO THE ARKLATEX WILL SUPPORT AT
LEAST ONE MORE DAY OF SLIGHTLY COOLER DEWPOINTS SUFFICIENT ENOUGH
TO KEEP WIDESPREAD HEAT INDEX VALUES AT OR BELOW 105 DEGREES.
DESPITE A FEW LOCATIONS THAT COULD EXPERIENCE SLIGHTLY HIGHER HEAT
INDEX VALUES WITHIN THE ADVISORY RANGE, COVERAGE DOESN'T SEEM
SUFFICIENT ENOUGH AT THIS TIME TO ISSUE ANY HEAT HEADLINES.
A NEARLY STAGNANT SYNOPTIC PATTERN WILL SUPPORT REPEAT CONDITIONS
ON FRIDAY AS WILL BE EXPERIENCED ON THURSDAY. HIGH TEMPERATURES
WILL AGAIN CLIMB INTO THE MID TO UPPER 90S WITH HEAT INDEX VALUES
APPROACHING ADVISORY CRITERIA. HOWEVER, THE SYNOPTIC PATTERN
BEGINS TO CHANGE DURING THE WEEKEND AS THE SURFACE PRESSURE
GRADIENT INCREASES SLIGHTLY ACROSS THE ARKLATEX WITH THE EASTWARD
DEPARTING SURFACE HIGH ALLOWING FOR LOW-LEVEL MOISTURE TO
INCREASE ACROSS THE REGION. ADDITIONALLY, AN UPPER-TROUGH ACROSS
THE EASTERN CONUS WILL RETROGRADE WESTWARD ALLOWING FOR INCREASED
INSTABILITY RESULTING IN A CHANCE FOR WIDELY SCATTERED DIURNALLY
DRIVEN CONVECTION MAINLY ACROSS NORTH LOUISIANA FROM SUNDAY
ONWARD. INSTABILITY AND MIXING ASSOCIATED WITH THE UPPER-TROUGH
COULD ALLOW FOR ENOUGH CLOUD COVER TO LIMIT AFTERNOON HIGH
TEMPERATURES TO THE LOWER TO MID 90S EACH DAY THROUGH THE WEEKEND
INTO EARLY NEXT WEEK. BY NEXT TUESDAY, THE UPPER-TROUGH WILL HAVE
SHIFTED INTO TEXAS ALLOWING FOR THE POSSIBILITY OF INCREASED
CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS AREAWIDE THROUGH
MIDWEEK. /05/
AVIATION
(06Z TAFS)
ISSUED AT 1253 AM CDT THU AUG 7 2025
FOR THE 07/06Z TAF PERIOD, VFR CONDITIONS WILL PREVAIL AS HIGH
PRESSURE AT THE SFC AND ALOFT CONTINUES TO DOMINATE OUR AIRSPACE.
THIS WILL RESULT IN MOSTLY SKC OVERNIGHT FOLLOWED BY A DEVELOPING
CU FIELD BY LATE MORNING THROUGH THE AFTERNOON HOURS, THEN QUICKLY
DIMINISHING AFTER 08/00Z. OTHERWISE, CANNOT RULE OUT SOME PATCHY
FOG WITH VERY MINOR VSBY REDUCTIONS AT A FEW SITES AROUND DAYBREAK
WITH LITTLE TO NO IMPACTS EXPECTED. NEAR CALM WINDS OVERNIGHT WILL
INCREASE FROM THE S/SE BETWEEN 5-10 KTS THROUGH THE DAYTIME HOURS
BEFORE DIMINISHING ONCE AGAIN AFTER 08/00Z.
