.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
A LARGE THUNDERSTORM COMPLEX WILL CONTINUE TO TRACK
SOUTHEAST...EVENTUALLY IMPACTING KMLC AND KFSM AFTER 13-14Z.
GUSTY WINDS WILL BE POSSIBLE THIS MORNING...WITH A WEAKENING
TREND EXPECTED LATE THIS MORNING. AREAS OF MVFR/IFR CIGS
AND VSBYS WILL BE POSSIBLE IN THE RAIN AREAS. AREAS OF
SHOWERS/FEW STORMS MAY REDEVELOP TONIGHT...MAINLY AFTER 06Z.

.PREV DISCUSSION... /ISSUED 254 AM CDT SUN AUG 23 2015/

DISCUSSION...

THUNDERSTORMS ONGOING EARLY THIS MORNING ACROSS PORTIONS OF SOUTH
CENTRAL AND SOUTHEAST KANSAS...POISED TO MOVE INTO NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS WITHIN THE NEXT FEW HOURS. THE
OVERALL SEVERE THREAT WITH THESE STORMS IS DIMINISHING...ALTHOUGH
AN ISOLATED EMBEDDED MARGINALLY SEVERE STORM OR TWO WILL REMAIN
POSSIBLE THROUGH ABOUT MID MORNING. HEAVY RAIN AND FLOODING
POTENTIAL WILL BE A CONCERN THOUGH...ESPECIALLY ACROSS PARTS OF
NORTHERN OTTAWA COUNTY AND PAWNEE COUNTY THAT SAW 3 TO 4 INCHES
OF RAIN YESTERDAY MORNING.

ADDITIONAL THUNDERSTORMS WILL REMAIN LIKELY THROUGH THE
DAY...FOCUSED ALONG THE COLD FRONT PUSHING THROUGH THE AREA. THE
FRONT WILL LIKELY BECOME STATIONARY SOMEWHERE NEAR THE RED RIVER
BY TONIGHT...WITH YET ANOTHER ROUND OF THUNDERSTORMS EXPECTED
OVERNIGHT NEAR THE 850 FRONT IN SOUTHEAST OKLAHOMA AND INTO WEST
CENTRAL ARKANSAS. THE THUNDERSTORM POTENTIAL WILL GRADUALLY SHIFT
FARTHER SOUTH AS THE SURFACE HIGH FINALLY ESTABLISHES ITSELF BY
TUESDAY.

FOR NOW...IT LOOKS LIKE NORTHWEST FLOW WILL DOMINATE THE WEATHER
PATTERN FOR NEXT WEEK...KEEPING BELOW NORMAL TEMPERATURES IN THE
FORECAST...AND LOW THUNDERSTORM CHANCES FROM MID WEEK ON. IT IS
WORTH NOTING THAT THE NEW GFS DOES NOT AGREE WITH THIS
SCENARIO...INSTEAD SHOWING THE UPPER LEVEL RIDGE BUILDING EASTWARD
INTO THE PLAINS STATES LATE IN THE WEEK AND INTO NEXT WEEKEND.
HOWEVER...THIS SOLUTION HAS BEEN DISCOUNTED AT THIS POINT...AS IT
HAS NO SUPPORT FROM ENSEMBLE GUIDANCE OR ANY OF THE FOREIGN
MODELS. TIMING INDIVIDUAL IMPULSES IN THE MEAN UPPER FLOW AND
THEREFORE...THE BEST STORM CHANCES THROUGH THIS PERIOD IS VERY
UNCERTAIN AT THIS POINT...SO HAVE OPTED TO JUST INCLUDE SLIGHT
CHANCE POPS WHEN NECESSARY.
