SHORT TERM
(THROUGH TONIGHT )
ISSUED AT 221 PM CDT WED MAY 28 2025
SUBTLE SHORTWAVE MOVING THROUGH BASE OF A LONGWAVE TROUGH ANCHORED
OVER THE UPPER MIDWEST IS RESULTING IN A FEW CLUSTERS OF SHOWERS
AND ISOLATED THUNDERSTORMS FROM CENTRAL KS BACK INTO FAR
NORTHWEST OK THIS AFTERNOON. THIS FEATURE WILL CONTINUE TO MOVE
EAST THROUGH LATE THIS AFTERNOON, WITH A FEW SHOWERS POSSIBLE IN
AREAS NEAR THE OK/KS BORDER INTO THE EVENING. GENERALLY STABLE
AIRMASS OVER NE OK AND NW AR SHOULD KEEP ANY THUNDERSTORMS AT BAY
IN THE VERY NEAR TERM.
LATER TONIGHT OUR ATTENTION TURNS TO A MORE SUBSTANTIAL WAVE
MOVING SOUTH NEAR THE FRONT RANGE AS IT ROUNDS THE BACK SIDE OF
THE LONGWAVE TROUGH. EXPECTATION REMAINS THAT THIS WILL AID IN
FAIRLY WIDESPREAD STORM DEVELOPMENT OVER THE HIGH PLAINS,
POTENTIALLY GROWING INTO AN MCS THAT WILL MOVE SOUTHEAST TOWARD
OUR FORECAST AREA. HOWEVER, GIVEN THE LESS FAVORABLE INSTABILITY
PROFILES, THIS COMPLEX WILL BE WEAKENING AS IT APPROACHES LATE
THIS EVENING AND CONTINUES TO PROPAGATE ESE OVERNIGHT. BOTH THE
SEVER AND HEAVY RAINFALL THREAT WILL BE RATHER LIMITED AS A
RESULT, AND CONFINED MAINLY TO AREAS WEST OF HIGHWAY 75.
LONG TERM
(TOMORROW THROUGH WEDNESDAY)
ISSUED AT 221 PM CDT WED MAY 28 2025
ABOVE MENTIONED STORM COMPLEX WILL RESULT IN AN OUTFLOW BOUNDARY
THAT WILL BE IN PLACE OVER THE FORECAST AREA THURSDAY. ADDITIONAL
SHOWERS AND THUNDERSTORMS ARE LIKELY TO DEVELOP ON THIS BOUNDARY
THROUGH THE DAY, WITH POCKETS OF HIGHER INSTABILITY DEVELOPING IN
THE AFTERNOON AND RESULTING IN A LIMITED SEVERE THREAT PRIMARILY
ACROSS SOUTHEAST OK AND WEST CENTRAL AR. SYNOPTIC FRONT WILL
EVENTUALLY PUSH THROUGH LATER IN THE DAY AND COULD FORCE
ADDITIONAL SHOWERS AND STORMS INTO THE EVENING.
DRY AND COOLER CONDITIONS THURSDAY NIGHT BEHIND THE FRONT WITH
LOWS IN THE 50S MOST PLACES, AND PERHAPS A FEW UPPER 40S NEAR KS
AND MO BORDERS. PLEASANT WEATHER FRIDAY AND MOST OF SATURDAY AS
WELL, HOWEVER AN ADDITIONAL SHORTWAVE IN NNW FLOW IS EXPECTED TO
MOVE THROUGH THE CENTRAL TOWARD THE SOUTHERN PLAINS LATE SATURDAY
BRINGING ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS TO PARTS OF
THE AREA.
A SHIFT IN THE LONGWAVE PATTERN WILL BEGIN TO FAVOR WARMER AND
MORE HUMID CONDITIONS AS A LONGWAVE TROUGH DEVELOPS OVER THE
WESTERN CONUS. DRY LINE WILL BECOME BETTER ESTABLISHED OVER
WESTERN OK/TX WITH SOUTHWEST FLOW ALOFT FAVORING ADDITIONAL STORM
CHANCES TO OUR WEST, AND SOME POTENTIAL FOR THEM TO MOVE INTO
PARTS OF OUR AREA EACH DAY.
AVIATION
(00Z TAFS)
ISSUED AT 629 PM CDT WED MAY 28 2025
VFR CONDITIONS WILL PREVAIL FOR MUCH OF THE NIGHT ACROSS THE
REGION, OUTSIDE OF ANY STORM ACTIVITY. A WEAKENING COMPLEX OF RAIN
AND STORMS IS EXPECTED TO SLIDE SOUTHEAST INTO NE OK AFTER MIDNIGHT,
AND MAY CONTINUE INTO NW AR THURSDAY MORNING. BRIEF GUSTY WINDS
AND LOWER VSBYS WILL ACCOMPANY ANY STORMS THAT IMPACT TERMINALS,
BUT CONFIDENCE ONLY MERITS A TEMPO GROUP AT THE NE OK SITES, AND A
PROB30 FOR THE NW AR SITES. MVFR CIGS WILL THEN OVERSPREAD NE OK
AND EVENTUALLY NW AR BEHIND A COLD FRONT ON THURSDAY, WITH A FEW
SPOTTY SHOWERS AROUND AS WELL. STORM CHANCES INCREASE AGAIN ACROSS
SE OK INTO W-CENTRAL AR THURSDAY AFTERNOON, AND PROB30 GROUPS WERE
USED AT KMLC AND KFSM FOR STORM POTENTIAL AT THOSE SITES.
