AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
337 AM CDT MON JUN 23 2008

.DISCUSSION...
LARGE BAND OF ELEVATED THUNDERSTORMS CONTINUE ACROSS SOUTHEAST
KANSAS...EXTENDING INTO NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS
IN REGION OF STRONG ISENTROPIC LIFT. THUNDERSTORM CLUSTERS ON
WESTERN EDGE OF CONVECTIVE BAND STRUGGLING TO MAINTAIN
ORGANIZATION AS WARM 850 MB TEMPS ADVECT IN STRONGER CAPPED LOW
LEVEL AIR MASS. STILL A LIMITED SEVERE THREAT FOR THE NEXT FEW
HOURS...PRIMARILY ACROSS CARROLL COUNTY AND VICINITY. TRYING TO
GAUGE PRECIP COVERAGE AFTER 12Z STILL REMAINS SOMEWHAT DIFFICULT
...HOWEVER GENERALLY WENT SIGNIFICANTLY HIGHER THAN MAV GUIDANCE
NORTHEAST OF A BVO/FYV LINE. GFS CONTINUES TO DEVELOP THUNDERSTORM
COMPLEX TOO FAR TO THE NORTHEAST AND DOESNT HAVE A GOOD HANDLE ON
ONGOING PRECIPITATION. KEPT SLIGHT CHANCE POPS ACROSS NORTHERN
ZONES THIS AFTERNOON AS ISOLATED THUNDERSTORMS COULD REDEVELOP
ALONG ANY RESIDUAL OUTFLOW BOUNDARIES/DIFFERENTIAL HEATING AREAS
DUE TO CLOUD COVER.

REST OF FORECAST REMAINS PRETTY BENIGN AS UPPER RIDGE BEGIN TO
BUILD IN FROM THE SOUTHWEST WITH A SLOW WARMING TREND. DID KEEP
MAINLY SLIGHT CHANCE POPS IN THE FORECAST ACROSS NORTHERN ZONES
SIMILAR TO THE MEX GUIDANCE.
