SHORT TERM
(THROUGH TONIGHT)
ISSUED AT 1112 AM CST THU MAR 5 2026
CORRIDOR OF ELEVATED CONVECTION PERSISTS NORTH OF A RETREATING
WARM FRONT LOCATED OVER FAR SOUTHEAST OK LATE THIS MORNING.
OVERALL INTENSITY CONTINUES TO WANE ACROSS SOUTHEAST OK INTO EAST
CENTRAL AR AT PRESENT, THOUGH SOME VERY LOCALIZED ADDITIONAL
AMOUNTS OF A HALF TO ONE INCH ARE STILL POSSIBLE NEAR AND A LITTLE
SOUTH OF THE I-40 CORRIDOR OVER THE NEXT FEW HOURS. AS WARM FRONT
CONTINUES LIFTING NORTH THROUGH THIS AFTERNOON AND EVENING, IT IS
POSSIBLE THAT SUBTLE ENERGY IN SOUTHWEST FLOW ALOFT MAY SPARK
ADDITIONAL ISOLATED SHOWERS OR STORMS, BUT THESE ARE NOT EXPECTED
TO BE SEVERE.
FOCUS FOR MORE ROBUST CONVECTION WILL SHIFT INTO SOUTHEAST OK AND
NORTHWEST TX THIS EVENING, WITH CAMS SUGGESTING AN EVOLUTION FROM
SUPERCELLS INTO AN INTENSE CLUSTER MOVING NORTHEAST AND
APPROACHING FAR NORTHEAST OK SOMETIME AFTER 06Z. EXPECTATIONS
REMAIN THAT THIS WILL BEGIN TO WEAKEN AS THE OVERALL ENVIRONMENT
BECOMES LESS FAVORABLE THROUGH EASTERN OK AND WESTERN AR. STILL A
DAMAGING WIND THREAT MAY CARRY INTO AREAS MAINLY WEST OF HIGHWAY
75 EARLY TONIGHT.
LONG TERM
(FRIDAY THROUGH THURSDAY)
ISSUED AT 1112 AM CST THU MAR 5 2026
FRIDAY STILL HAS THE POTENTIAL TO BE A MORE ACTIVE SEVERE WEATHER
DAY ACROSS THE LOCAL AREA, THOUGH THIS THREAT IS HIGHLY
CONDITIONAL. STRONG WESTERN CONUS UPPER LOW IS FORECAST TO
UNDERGO A SPLIT AS IT MOVES ACROSS THE ROCKIES WITH NORTHERN
BRANCH EVENTUALLY MOVING ACROSS THE PLAINS AND SOUTHERN BRANCH
CUTTING OFF TO THE SOUTHWEST. AS NORTHERN STREAM WAVE MOVES EAST,
SEASONABLY STRONG SOUTHWEST FLOW WILL SPREAD OVER OUR REGION, BUT
STRONGER FORCING SHOULD REMAIN TO OUR NORTH.
THERE ARE ALSO SIGNIFICANT UNCERTAINTIES WITH THE THERMODYNAMIC
ENVIRONMENT. ONGOING MORNING STORMS ACROSS NORTHEAST OK WILL MOST
LIKELY WEAKEN BY AFTERNOON, BUT COULD HAVE SOME IMPACT ON THE
OVERALL ENVIRONMENT IF IT LINGERS. IN ADDITION A STRONG EML WILL
SPREAD OVER THE REGION AND RESULT IN STRONG CAPPING WHICH COULD BE
TOUGH TO BREAK GIVEN RELATIVELY WEAK FORCING WITHIN THE WARM
SECTOR. SOME GUIDANCE CONTINUES TO BREAK OUT CONVECTION DURING THE
AFTERNOON WITHIN THE OPEN WARM SECTOR, WHICH WOULD POSE A THREAT
OF ALL MODES OF SEVERE WEATHER. BY EVENING, COLD FRONT OVERTAKES
THE DRY LINE LOCATED TO OUR WEST AND THIS LIKELY WILL FORCE A BAND
OF THUNDERSTORMS FRIDAY NIGHT AND PERHAPS INTO SATURDAY MORNING.
SEVERE THREAT WITH THIS WILL BE LESSER. HEAVY RAINFALL THREAT
REMAINS PRESENT AS PWAT VALUES REMAIN WELL ABOVE 90TH PERCENTILE,
WITH STRONGER STORMS CAPABLE OF 3-4" PER HOUR RAIN RATES LOCALLY.
AS COLD FRONT SWEEPS SOUTH BY SATURDAY, GENERALLY COOLER AND DRIER
CONDITIONS PREVAIL ASIDE FROM PARTS OF SOUTHEAST OK WHICH REMAIN
NEAR THE 850 MB FRONT. THIS EVENTUALLY PUSHES SOUTH WITH RAIN
CHANCES ENDING, LIKELY SATURDAY EVENING. COOLER AIR WILL RESULT
IN POTENTIAL FOR A LIGHT FROST OR FREEZE NEAR OK/KS BORDER AND
PERHAPS FAR NORTHWEST AR. THE SW CONUS CUTOFF LOW IS EVENTUALLY
EXPECTED TO PHASE WITH NORTHERN STREAM ENERGY NEXT WEEK, WITH
RAIN AND THUNDERSTORM CHANCES RETURNING TUE/WED.
AVIATION
(18Z TAFS)
ISSUED AT 1112 AM CST THU MAR 5 2026
A FEW SHOWERS AND PERHAPS AN ISOLATED THUNDERSTORM OR TWO WILL
PERSIST ACROSS SE OK OVER THE NEXT COUPLE OF HOURS. KMLC AND KFSM
WILL HAVE THE HIGHEST CHANCES OF PRECIPITATION OVER THE NEXT FEW
HOURS. MVFR AND IFR CIGS SHOULD TRANSITION TO MORE PREVAILING VFR BY
LATE AFTERNOON OR EARLY THIS EVENING FOR MOST TERMINALS. VFR IS
EXPECTED TO BE SHORT-LIVED AS MVFR CIGS ARE EXPECTED TO PREVAIL BY
OR AROUND SUNRISE FRIDAY. ANOTHER STORM COMPLEX IS FORECAST TO
DEVELOP ACROSS WESTERN/CENTRAL OK TONIGHT AND PUSH INTO PORTIONS OF
NE OK AFTER MIDNIGHT TONIGHT. AT THIS TIME, IT APPEARS KBVO, KTUL,
AND KRVS HAVE THE BEST CHANCE BEING IMPACTED BY THIS CONVECTION
THROUGH AT LEAST MID MORNING. HAVE INCLUDED TEMPO GROUPS TO CAPTURE
THIS CHANCE. OTHERWISE, WINDS WILL REMAIN OUT OF THE SOUTH,
REMAINING LIGHT THROUGH THIS AFTERNOON. SOUTHERLY WINDS WILL
INCREASE AND BECOME GUSTY THIS EVENING, OVERNIGHT, AND INTO
TOMORROW.
