PORTIONS OF SW AR HAVE RECEIVED CONSIDERABLE RAINFALL OVER THE
PAST 12-24 HOURS, W/ MRMS QPE HIGHLIGHTING BANDS OF 8-10+ INCHES
OVER FAR SWRN AR (MAINLY W/IN THE SHREVEPORT CWA), AND PORTIONS
OF THE OUACHITA MOUNTAINS HAVING RECEIVED 2-3 INCHES AS OF WED
AFTN. SHORT TERM CAM GUIDANCE HAS BEEN TRENDING TOWARDS A SIMILAR
OVERNIGHT PATTERN LATE WED NIGHT INTO EARLY THURS MRNG, W/ ANOTHER
ROUND OF CONSIDERABLE TO EXCESSIVE RAINFALL POSSIBLE ACRS
PORTIONS OF WRN TO SWRN AR. A WEAK LLJ IS SET TO DEVELOP OVER THE
ARKLATEX REGION LATE TONIGHT, ACCOMPANIED BY PWATS NEAR 2 INCHES
OR MORE. GIVEN THAT THERE IS ANTECEDENT FLOODING IN SOME AREAS,
AND REGIONAL SOILS WILL BE PRIMED FOR FASTER RUNOFF, HAVE
INCLUDED MUCH OF THE OUACHITAS IN A FLOOD WATCH THROUGH THURS

DISCUSSION
ISSUED AT 308 AM CDT WED JUN 24 2026
SHOWERS AND ISOLATED THUNDERSTORMS WERE ONGOING OVER PORTIONS OF
N/CNTRL/SE AR THIS MORNING. THIS ACTIVITY IS EXPECTED TO EXPAND IN
COVERAGE THROUGH THE PREDAWN HOURS THANKS TO A PASSING WEAK UPPER
LEVEL SHORTWAVE. TODAY, SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO REDEVELOP WITH THE APPROACH OF A SECONDARY WEAK UPPER
LEVEL SHORTWAVE SET TO TRAVERSE THE REGION LATER THIS AFTERNOON.
UPPER LEVEL WIND PROFILES WILL FAVOR AN ENVIRONMENT CONDUCIVE FOR
TRAINING OF STORMS, GIVEN THIS, FLASH FLOODING WILL BE THE
GREATEST THUNDERSTORM HAZARD. DAMAGING WINDS CAN NOT BE RULED OUT
WITHIN STRONGER CONVECTION. HIGHS TODAY ARE EXPECTED TO BE IN THE
LOWER TO MID 80S. WINDS TODAY WILL BE OUT OF THE S/SW AT AROUND 10
MPH. DEW PT TEMPS ARE EXPECTED TO CREEP BACK INTO THE LOW/MID 70S
BY THE AFTERNOON.
SYNOPTICALLY, NW FLOW WILL BE IN PLACE ACROSS THE REGION THROUGH MID
WEEK. BY LATE WEEK, NW FLOW SHOULD BRIEFLY TRANSITION TO ZONAL FLOW,
THEN BECOME SW FLOW AS UPPER LEVEL RIDGE TAKES SHAPE OVER THE SE
U.S.. HEADING INTO EARLY NEXT WEEK, THE UPPER LEVEL RIDGE SHOULD BE
SITUATED OVERTOP THE CNTRL/SRN MS VALLEY INTO THE THE TN AND OH
VALLEY REGIONS.
EARLY IN THE PERIOD, UPPER LEVEL DISTURBANCES ARE EXPECTED TO
TRAVERSE NW FLOW ON A NEAR DAILY BASIS RESULTING IN MCS DEVELOPMENT
AND/OR BROKEN COMPLEXES OF SHOWERS AND THUNDERSTORMS. ONCE COMPLEXES
DEVELOP, THEY SHOULD TRACK SE OVER THE REGION. THE MAIN HAZARDS WITH
THESE STORMS WILL BE FLASH FLOODING AND DAMAGING WINDS. DAILY POP
CHANCES WILL START TO WANE BY THE WEEKEND WITH TEMPS CLIMBING BACK
ABOVE TO WELL ABOVE AVERAGE.
LARGE SCALE FORCING FOR SUBSIDENCE SHOULD SUPPRESS ORGANIZED
RAINFALL ACROSS THE AREA INTO EARLY PORTION OF NEXT WEEK. WITH HIGH
ANTECEDENT SOIL MOISTURE IN PLACE (THANKS TO RECENT RAINFALL)
COUPLED WITH WARM AND MOIST AIR ADVECTION ON S/SWRLY WINDS, TEMPS
ARE EXPECTED TO CLIMB INTO THE MID/UPPER 90S WITH APPARENT T'S
REACHING OR EXCEEDING HEAT HEADLINE CRITERIA. HEAT RISK IS ALSO ON
PAR FAVORING MAJOR RISK CATEGORY LATE IN THE PERIOD (DRIVEN MAINLY
BY WARM OVERNIGHT LOWS). TALKING ABOUT WARM OVERNIGHT TEMPS,
READINGS MAY STRUGGLE TO FALL BELOW 80 DEGREES IN AR RIVER VALLEY,
CNTRL AR, AND ERN AR SUNDAY NIGHT THROUGH AT LEAST TUESDAY NIGHT.
WBGT TEMPS MAY APPROACH UPPER 80S/NEAR 90 OVER PORTIONS OF CNTRL
AR INTO ERN SECTIONS OF THE STATE SUNDAY AFTERNOON THROUGH TUESDAY
AFTERNOON. LONG RANGE GUIDANCE SUGGESTS THE UPPER LEVEL RIDGE
COULD LINGER OVER THE REGION BEYOND THE END OF THE LONG TERM
PERIOD. THIS WOULD PROLONG THE PERIOD OF DANGEROUS HEAT
ANTICIPATED ACROSS AR.
AVIATION
(00Z TAFS)
ISSUED AT 650 PM CDT WED JUN 24 2026
WEAK SHOWERS ACROSS CENTRAL TO NORTHERN ARKANSAS IS THE ONLY
NOTEWORTHY WEATHER OCCURRING EARLY THIS EVENING, WITH SOME SHRA
AND INTERMITTENT MVFR CEILINGS. ANTICIPATING A DOWNTREND IN
RAINFALL COVERAGE PRIOR TO ANOTHER UPTICK IN SHOWERS AND STORMS
DURING THE OVERNIGHT PERIOD, FAVORING CENTRAL TO SOUTHERN
ARKANSAS. LOW TO MODERATE CONFIDENCE IN THIS SCENARIO GIVEN
UNCERTAINTIES IN TIMING AND LOCATION. SHOWERS AND STORMS COULD
LINGER IN SOME FORM ACROSS ANY PART OF THE STATE INTO AND THROUGH
THE AFTERNOON HOURS, SO WILL HAVE TO KEEP AN EYE ON HOW CONDITIONS
EVOLVE TONIGHT GOING INTO TOMORROW MORNING.
