DISCUSSION
(TODAY THROUGH THURSDAY)
ISSUED AT 1216 AM CDT FRI AUG 28 2026
THE FORECAST AREA REMAINS SITUATED BENEATH A N/NW FLOW ALOFT
TONIGHT, BETWEEN RIDGING OVER THE DESERT SW AND TROUGHING OVER THE
E/NE CONUS. AT THE SURFACE, A WEAK STATIONARY BOUNDARY IS DRAPED
ACROSS THE ARK-LA-TEX REGION, WHERE IT WILL LINGER THROUGHOUT OUR
FRIDAY. THIS SYNOPTIC SET UP WILL RESULT IN ANOTHER HOT AND MOSTLY
DRY DAY, WITH ONLY MINIMAL CHANCES FOR AFTERNOON CONVECTION. WHILE
HIGHS WARM INTO THE LOW TO MID-90S THIS AFTERNOON, SLIGHTLY LOWER
THAN NORMAL DEWPOINTS THANKS TO THE FLOW ALOFT WILL AGAIN KEEP
HEAT INDICES IN CHECK.
MOVING INTO THE WEEKEND, AFOREMENTIONED SURFACE BOUNDARY SAGS A BIT
FURTHER SOUTH, WITH NBM INDICATING A BRIEF PERIOD OF N TO NE SURFACE
FLOW AROUND SUNRISE THROUGH MIDDAY TOMORROW. ALOFT, THE DESERT SW
RIDGING BEGINS TO SHIFT EASTWARD BECOMING SITUATED ACROSS THE
SOUTHERN PLAINS TOMORROW EVENING INTO SUNDAY. THIS WILL ALLOW
DEWPOINTS TO FALL INTO THE MID 60S ACROSS CENLA AND UPPER 60S TO
LOWER 70S ELSEWHERE THROUGH TOMORROW AFTERNOON, WHILE ALSO CAUSING
POPS TO FALL TO NEAR ZERO. THIS SHOT OF 'DRIER' AIR WILL HOLD
AFTERNOON HEAT INDICES IN THE LOW TO MID 100S, WHILE HIGHS TOP OUT
IN THE MID TO UPPER 90S.
SUNDAY INTO MONDAY BRINGS A BIT OF UNCERTAINTY, AS SOME GUIDANCE
DEPICTS A WEAK EASTERLY WAVE TRAVERSING THE NORTHERN GULF COAST
BENEATH THE EXPANDING UPPER RIDGE. IF THIS OCCURS, IT WOULD BRING
WITH IT AN UPTICK IN RAIN CHANCES HOWEVER, NBM WANTS TO KEEP THE
BETTER POPS TO OUR EAST FOR NOW. WITH SO MUCH UNCERTAINTY REGARDING
THIS FEATURE OPTED TO LEAVE POPS ALONE FOR NOW, BUT I WOULND'T BE
SURPRISED TO SEE THEM INCREASE SOMEWHAT ESPECIALLY FOR LOWER
ACADIANA. OTHERWISE, THE REMAINDER OF THE FORECAST PERIOD WILL
CONSIST OF UPPER RIDGING BUILDING ACROSS THE MS RIVER VALLEY WITH
THE FORECAST AREA ON THE SOUTHERN EXTENT. THE PROXIMITY TO THIS
RIDGE WILL ALLOW AFTERNOON HIGHS TO CONTINUE TO REACH INTO THE MID
TO UPPER 90S MOST DAYS, WHILE SMALL CHANCES FOR AFTERNOON DIURNALLY
DRIVEN SHOWERS AND THUNDERSTORMS CONTINUE EACH DAY WELL INTO NEXT
WEEK.

RANGE ACROSS INTERIOR SE TX/CENLA BOTH SAT AND SUN. MOISTURE WILL
RETURN AREA-WIDE BY THE START OF THE WORK WEEK WITH MINRH VALUES
BACK IN THE 50 TO 60% RANGE AREAWIDE. THE ENTIRE REGION REMAINS
