AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE WICHITA KS
1200 PM CDT SAT MAY 10 2003

UPDATED THE ZONES TO FRESHEN UP SEVERE WORDING FOR SOME OF THE AREA.
SHARP DRYING WITH DYLINE MOVING THROUGH SOUTH CENTRAL KANSAS
ATTM...BUT SFC WINDS VEERING OUT WELL E OF ICT. LINE OF CU ALONG THE
WINDSHIFT LINE IS CROPPING UP QUITE QUICKLY FROM AN IOLA/CHAUTAUQUA
LINE. CAPES AND SHEAR BOTH HIGH E OF THIS LINE...AND IF STORMS CAN GO
BEFORE THE WINDSHIFT LINE EXITS THE CWA...TORNADOES WILL BE POSSIBLE.
PDS TOR BOX HAS BEEN ISSUED FOR ALLEN, NEOSHO, LABETTE, MONTGOMERY,
WILSON TIL 00Z. THIS WILL NO DOUBT BE CANCELLED EARLY...BUT HAS BEEN
ISSUED IN CASE THIS CONVCTN FIRES FAST. AS FOR THE REST OF THE
CWA...NO BIG CHANGES TO THE GRIDS/ZONES.

EKSTER

-------------------------------7AM DISC-----------------------------
WE HAVE UPDATED THE GRIDS TO LOWER THE TSRA CHANCES THIS MORNING. IT
APPEARS THAT THE ONLY FOCUS FOR CONVECTION THIS MORNING MAY BE ALONG
CONVECTIVE OUTFLOWS FROM THE PREVIOUS MCS TRACKING THROUGH NORTHERN
MISSOURI. OTHERWISE, ACTIVITY SHOULD REFIRE AGAIN THIS AFTERNOON
MAINLY ALONG AND EAST OF THE DRY LINE. LATEST MESOETA/RUC SHOWS THE
FRONT/DRY LINE EXITING SOUTHEAST KANSAS BY 00Z. WITH LIMITED CAP IT
WILL NOT TAKE MUCH TO SET THINGS OFF IN THAT AREA WITH CAPES ON THE
ORDER OF 4000 G/KG.

---------------------------------------------------------------------
COX

MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE HOW LONG THE
CONVECTION WILL LINGER THIS MORNING AND THE POTENTIAL FOR MORE
AFTERNOON CONVECTION ALONG AND EAST OF DRY LINE.

TODAY:
ONGOING CONVECTION CURRENTLY MOVING THROUGH CENTRAL KS WILL CONTINUE
TO SURGE NORTHEAST AND EXIT MOST OF THE CWFA BY DAYBREAK. WE MAY SEE
SOME WIDELY SCATTERED CONVECTION DEVELOP TO THE SOUTH OF THE
SUPERCELL MOVING THROUGH MARION AND BUTLER COUNTIES. HOWEVER, AT
THIS TIME IT APPEARS THAT MOST OF THE CONVECTION WILL REMAIN NORTH
OF THE CWFA. THE NEXT QUESTION WILL BE HOW FAR EAST THE DRY LINE
WILL PROGRESS EAST. MODELS SUGGEST THINGS MAY FIRE AGAIN ALONG THE
DRY LINE LATE THIS AFTERNOON IN SOUTHEAST KANSAS. AS A RESULT, WE
ARE GOING TO MENTION THE POTENTIAL OF SEVERE STORMS IN THAT REGION
DUE TO HIGH CAPE AND STILL DECENT SHEAR.

TONIGHT-MONDAY NIGHT:
IT SHOULD FINALLY TURN QUIET AS THE UPPER LEVEL WAVE PUSHES INTO THE
GREAT LAKES AND ALLOWS FOR HIGH PRESSURE TO BUILD IN. TEMPERATURES
WILL BE ON THE COOL SIDE AS TEMPERATURES PLUMMET TO THE LOWER TO MID
40S WITH HIGHS MAINLY IN THE 60S.

TUESDAY-FRIDAY:
GFS TRIES TO PEEL DOWN AN UPPER LEVEL SYSTEM FROM THE NORTHERN
PLAINS INTO THE OHIO VALLEY. THE OTHER MODELS DO NOT REFLECT THIS
SCENARIO, BUT THE GFS HAS BEEN THE MOST CONSISTENT WITH THIS
FEATURE. AS A RESULT, WE MENTIONED A CHANCE OF TSRA ON TUESDAY AS
THE FRONTAL BOUNDARY MOVES THROUGH. THE REMAINDER OF THE FORECAST
REMAINS UNCHANGED DUE TO UNCERTAINITY IN THE MODEL SOLUTIONS. FCSTID

NATIONAL WEATHER SERVICE WICHITA KS
1130 PM CDT SAT MAY 10 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL AND SOUTHEAST KANSAS.

.DAY ONE...TODAY AND TONIGHT

THE DRY LINE CURRENTLY SITUATED IN SOUTH CENTRAL KANSAS WILL MOVE
EAST THIS AFTERNOON. AS A RESULT, MORE THUNDERSTORMS WILL FIRE ALONG
AND EAST OF THIS LINE THIS AFTERNOON WITH SOME OF THE STORMS
BECOMING SEVERE. THE AREA OF GREATEST THREAT WILL BE EAST OF AND
INCLUDING GREENWOOD, ELK, AND CHAUTAUQUA COUNTIES. THE POTENTIAL FOR
LARGE HAIL AND DAMAGING WINDS WILL BE POSSIBLE IN THESE AREAS.
HOWEVER, SOME ISOLATED TORNADOES CANNOT BE RULED OUT...ESPECIALLY IN
EXTREME SOUTHEAST KANSAS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A WEAK COLD FRONT WILL TRACK THROUGH CENTRAL AND SOUTHEAST KANSAS
MONDAY NIGHT AND TUESDAY. THIS FRONT WILL TRIGGER SHOWERS AND
THUNDERSTORMS ACROSS THE AREA. THE EXACT TRACK OF THE UPPER LEVEL
SYSTEM ASSOCIATED WITH THE FRONT IS STILL UNKNOWN. SO STAY TUNED TO
LATER STATEMENTS CONCERNING THIS SITUATION.

ANOTHER UPPER LEVEL SYSTEM WILL MOVE INTO THE REGION DURING THE
MIDDLE OF THE WEEK AND GIVE ANOTHER CHANCE OF THUNDERSTORMS TO THE
AREA.
