DISCUSSION...
EXTENDED THE HEAT ADVISORY THROUGH THURSDAY ACROSS OUR NORTHERN
THIRD AND OUR EASTERN THIRD WHICH INCLUDES THE MIDDLE RED RIVER
VALLEY OF SE OK/EXTREME NE TX AS WELL AS ALL OF SW AR AND OUR NE
LA PARISHES. WHILE IT DOES APPEAR THAT WE WILL SEE SLIGHTLY MORE
MIXING DOWN OF DEWPOINTS DURING PEAK HEATING THIS AFTERNOON AND
AGAIN ON THURSDAY ACROSS NE TX...FEEL LIKE THE MODELS ARE MIXING
DEWPOINTS DOWN TOO MUCH ACROSS THE ADVISORY AREA. THIS IS
SOMETHING THE SHORT TERM PROGS HAVE STRUGGLED WITH THE LAST
SEVERAL DAYS BUT WE SHOULD FALL JUST SHORT OF 105 DEGREE HEAT
INDEX TEMPS TODAY AND THURSDAY ACROSS THE SHREVEPORT/BOSSIER CITY
METRO AREA. THIS IS NOT TO SAY THAT IT WILL NOT REMAIN HOT ACROSS
THOSE AREAS NOT INCLUDED IN THE ADVISORY AREA THROUGH THURSDAY
WHERE HEAT INDEX VALUES WILL REMAIN NEAR 101-104 DEGREES DURING
PEAK HEATING.
CENTER OF THE UPPER LEVEL RIDGE CENTERED ACROSS THE HEART OF OUR
REGION TODAY WILL REMAIN ANCHORED ACROSS OUR REGION THROUGH THE
UPCOMING WEEKEND INTO AT LEAST MONDAY. THERE IS SOME INDICATION
THAT THE RIDGE WILL BEGIN TO BREAK DOWN TUESDAY INTO WEDNESDAY OF
NEXT WEEK AS UPPER FLOW BECOMES SLIGHTLY MORE FROM THE SOUTHWEST.
THIS MAY ALLOW FOR SLIGHT CHANCE POPS LATE MONDAY INTO THE MIDDLE
OF NEXT WEEK ACROSS PORTIONS OF OUR REGION. PREVIOUS FORECAST
INCLUDED THIS IN THE EXTENDED GRIDS AND WILL KEEP THIS MENTION IN
THE FORECAST FOR NOW.
OTHERWISE...PERSISTENCE WILL REMAIN THE BEST FORECAST TOOL THROUGH
AT LEAST EARLY NEXT WEEK WITH THE HEAT HERE TO STAY. THANKS FOR
THE COORDINATION THIS MORNING LZK/JAN.
PRELIMS TO FOLLOW...13.
