SHORT TERM
(THIS EVENING THROUGH SUNDAY NIGHT)
ISSUED AT 225 PM CDT SAT MAY 24 2025
AS LATE SPRING MCS SEASON GOES HERE IN OUR REGION, THIS MORNING'S
THUNDERSTORM COMPLEX THAT ORIGINATED WELL UPSTREAM STILL MANAGED
TO HOLD TOGETHER WELL SOUTH INTO OUR NORTHERN ZONES. IN FACT, IT'S
STILL PACKING QUITE A PUNCH AS SEVERE THUNDERSTORM WARNINGS REMAIN
ACTIVE WHILE IT BEGINS TO ADVANCE JUST TO OUR EAST INTO THE DELTA
REGION OF THE LOWER MS VALLEY. MEANWHILE, WE ARE STILL MONITORING
SOME UPSTREAM CONVECTION NORTH OF MCCURTAIN COUNTY IN SE OK, BUT
MORE RECENT RADAR TRENDS ARE INDICATING SOME GRADUAL WEAKENING AS
THIS CONVECTION SHIFTS FARTHER SE. WITH THAT SAID, PLAN TO LET THE
CURRENT SEVERE THUNDERSTORM WATCH ACROSS OUR NORTHERN ZONES EXPIRE
ON SCHEDULE AT 3 PM.
ADDITIONAL OUTFLOW DRIVEN CONVECTION REMAINS POSSIBLE THROUGH THIS
AFTERNOON OVER MUCH OF THE REGION, BUT COVERAGE SHOULD GRADUALLY
WANE AS WE APPROACH SUNSET THIS EVENING. MEANWHILE, RENEWED MCS
DEVELOPMENT IS EXPECTED TO OUR N/NW OVERNIGHT, BUT A SLIGHT NORTH
TO NORTHEASTWARD EXPANSION OF THE UPPER-LEVEL RIDGE AXIS INTO OUR
REGION SHOULD HELP TO DEFLECT THE MAJORITY OF CONVECTION TO OUR
NORTH. THEREFORE, EXPECT A MOSTLY RAIN-FREE OVERNIGHT PERIOD WITH
WARM AND MUGGY CONDITIONS ONCE AGAIN WITH LOWS GENERALLY RANGING
FROM THE UPPER 60S TO MIDDLE 70S. THE SLIGHTLY MILDER TEMPERATURES
WILL REMAIN CONFINED TO OUR FAR NORTHERN ZONES WHERE A STATIONARY
BOUNDARY REMAINS ORIENTED, GENERALLY ALONG THE OUACHITAS EASTWARD.
MOVING AHEAD TO SUNDAY AND SUNDAY NIGHT, THE UPPER-LEVEL RIDGE
WILL BEGIN TO FLATTEN OUT ACROSS OUR REGION AND SHIFT FARTHER EAST
WHILE THE SFC BOUNDARY REMAINS QUASI-STATIONARY NEAR TO JUST NORTH
OF OUR REGION. MUCH LIKE TODAY, WE WILL BE WATCHING FOR ADDITIONAL
OUTFLOW DRIVEN CONVECTION FROM THE AFOREMENTIONED UPSTREAM MCS AND
HOW THIS MAY IMPACT RAIN CHANCES ACROSS OUR REGION. FOR THE MOST
PART, DON'T ANTICIPATE MUCH CONVECTIVE COVERAGE OVERALL DURING THE
DAYTIME PERIOD BUT INCREASING CHANCES WILL COME BY SUNDAY EVENING
AND OVERNIGHT. THIS INCLUDES THE POSSIBILITY OF SEVERE WEATHER AS
STRONG DAYTIME HEATING WILL CONTRIBUTE TO MODEST INSTABILITY EVEN
THOUGH SHEAR WILL CONTINUE TO BE LACKING. ANY SEVERE THUNDERSTORMS
THAT DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING WINDS AND
LARGE HAIL NORTH OF THE I-20, AND MAINLY ALONG AND NORTH OF I-30
WHERE FRONTAL FORCING WILL BE GREATER.
/19/
LONG TERM
(MONDAY THROUGH NEXT FRIDAY)
ISSUED AT 225 PM CDT SAT MAY 24 2025
LOOKING AHEAD TO MEMORIAL DAY AND FURTHER INTO NEXT WEEK, LOOK FOR
CONVECTION TO BECOME MORE WIDESPREAD AS THE FRONTAL BOUNDARY GAINS
SOME FORWARD MOMENTUM INTO MORE OF OUR REGION THROUGH EARLY TO MID
WEEK. BASED ON THE LATEST GUIDANCE, IT APPEARS THE FRONT MAY NOT
FULLY ADVANCE INTO OUR REGION UNTIL TUESDAY BEFORE EVENTUALLY
PUSHING SOUTH OF THE REGION ON WEDNESDAY. THIS WILL ALLOW FOR
MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS TO AFFECT THE REGION
DURING THIS EARLY TO MID WEEK PERIOD, INCREASING THE THREAT OF
HEAVY RAINFALL AND FLASH FLOODING.
ADDITIONAL SHORTWAVE DISTURBANCES MOVING THROUGH THE UPPER-LEVEL
FLOW PATTERN WILL MAINTAIN AN UNSETTLED PATTERN THROUGHOUT THE
REMAINDER OF THE WEEK. EVENTUALLY, THE LONGWAVE TROUGH TAKING UP
RESIDENCE ACROSS MUCH OF THE EASTERN AND SOUTHERN CONUS SHOULD
BEGIN TO PIVOT EASTWARD AND FINALLY BRING AN END TO THE PROLONGED
PERIOD OF WET AND STORMY WEATHER. WITH THAT SAID, RAINFALL AMOUNTS
THROUGHOUT THIS 7-DAY PERIOD FROM THIS WEEKEND INTO NEXT WEEK MAY
RANGE FROM 3-6 INCHES WITH ISOLATED HIGHER TOTALS POSSIBLE BEFORE
ALL OF THE CONVECTION FINALLY COMES TO AN END.

AVIATION
(18Z TAFS)
ISSUED AT 1233 PM CDT SAT MAY 24 2025
FOR THE 24/18Z TAFS, MVFR TO LOWER VFR CIGS PREVAIL AS THE CLOUD
DECKS OF THIS AFTERNOON'S CU FIELD OVERSPREAD OUR SOUTHERN AND
WESTERN AIRSPACE. A LINE OF SHOWERS AND STORMS CONTINUE TO MOVE
SOUTH AND EASTWARD ACROSS SOUTHWEST ARKANSAS, WITH FURTHER
CONVECTION ARRIVING FROM THE NORTHWEST, AND ISOLATED POP UP
CONVECTION AHEAD AND SOUTH OF THE MAIN LINE. THESE SHOWERS AND
STORMS LOOK TO COME TO AN END BY SUNDOWN, FOLLOWED BY A MOSTLY
QUIET NIGHT AND NEW STORMS LATE IN THE PERIOD TOMORROW. SOUTHERLY
TO SOUTHEASTERLY WINDS WILL CONTINUE AT SUSTAINED SPEEDS OF 5 TO
10 KTS WITH GUSTS OF UP TO 20 KTS POSSIBLE THROUGHOUT.
