AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE WICHITA KS
734 PM CDT SAT MAY 21 2005

.UPDATE...
A FEW STORMS HAVE DEVELOPED ALONG A WEAK FRONTAL BOUNDARY IN CENTRAL
KANSAS WHERE CONVECTIVE TEMPERATURES WERE REACHED LATE THIS
AFTERNOON. IT APPEARS AS IF THESE STORMS ARE HAVING A DIFFICULT TIME
ESTABLISHING GOOD UPDRAFTS. IT IS ALSO APPARENT THAT THESE STORMS
ARE LOW PRECIPITATION MAKERS DUE TO WIDE TEMPERATURE/DEWPOINT
SPREADS. IN FACT, WE MADE A FEW CALLS TO SOME OBSERVERS THAT WERE
AFFECTED BY THESE CELLS AND THEY WERE NOT PRODUCING ANY RAIN. IF
THESE STORMS CAN ESTABLISH A GOOD UPDRAFT AS THEY MOVE EAST THEY
COULD PRODUCE SOME DAMAGING WIND GUSTS DUE TO GOOD DIRECTIONAL AND
SPEED SHEAR ACCORDING TO HILLSBORO PROFILER. IF THESE STORMS CAN MAINTAIN
DURING THE NEXT COUPLE OF HOURS. CORFIDI VECTORS COULD TAKE THEM
INTO PORTIONS OF SOUTH CENTRAL AND SOUTHEAST KANSAS THIS EVENING WHERE
THE BETTER MOISTURE WILL BE IN PLACE. WE WILL ALSO HAVE TO WATCH
NORTHEAST KANSAS FOR POTENTIAL CONVECTION THIS EVENING, BUT THIS
ENVIRONMENT STILL IS CAPPED.

&&

.PREV DISCUSSION... /ISSUED 315 PM CDT SAT MAY 21 2005/

.DISCUSSION...

CONCERNS TONIGHT ARE PRECIP, IF ANY AND THEN CHANCES MIDWEEK.

THIS EVE-TNGT:
WARM TEMPS ALOFT HAVE LEAD TO A PRETTY SUBSTANTIAL CAPPING INVERSION
ACROSS MOST OF CEN/SRN KS, WITH CAP WEAKEST NORTHEAST OF THE AREA.
LOTS OF MOISTURE/INSTABILITY IN THE LOW LAYERS HAS LEAD TO A RATHER
HUMID AIRMASS IN PLACE ACROSS THE AREA.  BUT WITH CAP HOLDING TIGHT
AND LACK OF ANY SIGNIFICANT FORCING TO HELP DESTABILIZE THINGS, TSRA
CHANCES LOOK TO BE SLIM FOR AREAS SOUTHWEST OF I-135. DO EXPECT
CONVECTION TO GET GOING FURTHER NORTHEAST OF THE AREA IN ERN NEB,
WITH AN MCS PROPAGATING S/SE INTO NORTHEAST KS.  THIS MCS CHANCE
ALSO LOOKS TO STAY NORTHEAST OF THE AREA, POSSIBLY CLIPPING THE
ERN/SERN EDGE OF KS BY MORNING AS MAIN COLD FRONTAL BOUNDARY PUSHES
ACROSS THE AREA, SO WILL KEEP A LOW POP IN AREAS MAINLY EAST OF THE
FLINT HILLS IN CASE CAP WEAKENS ENOUGH FOR ANYTHING TO GET GOING.

SUN-MON:
FRONTAL BOUNDARY SLOWS DOWN OR STALLS OVER SERN KS EARLY SUN.
COULD SEE SOME LINGERING SHRA/TSRA IN SERN KS ALONG THIS BOUNDARY
DURING THE AFTN HOURS, BUT THIS CHANCE WILL QUICKLY END AS BOUNDARY
SAGS A LITTLE FURTHER SOUTH INTO OK. LOTS OF INSTABILITY FOR A SHORT
LIVED SVR CHANCE.

SO WILL END PRECIP CHANCES ACROSS THE AREA SUN EVE INTO MON, AS
WEAK RIDGING MOVES ACROSS THE AREA IN THE NW ZONAL FLOW.

LOTS OF MODEL DIFFERENCES STARTING MON NIGHT AS BOUNDARY BECOMES
QUASI-STATIONARY JUST SOUTH OF THE KS/OK BORDER, WITH UPSLOPE FLOW
NORTH OF THE BOUNDARY LEADING TO SOME KIND OF MCS ACTIVITY IN NW/WRN
KS. GFS TRIES TO BRING SOME OF THIS ACTIVITY INTO CEN KS EARLY TUE,
BUT LOTS OF UNCERTAINTIES IN THIS WITH NAM KEEPING THINGS SW OF THE
AREA. HARD TO GRASP ON ANY ONE SOLUTION, SO WILL KEEP THIS TIME
FRAME DRY FOR NOW.

TUE-THU:
TOUGH FORECAST PERIOD IN THE MID WEEK PERIOD. MED RANGE MODELS IN
FAIRLY GOOD AGREEMENT, WITH ZONAL FLOW IN THE UPPER LEVELS. BUT THE
BIG ISSUE IS THE PLACEMENT OF THE LOW LEVEL MOISTURE AND THERMAL
GRADIENT EXPECTED TO BE ACROSS SRN PORTIONS OF KS.  MODELS SEEM TO
SUGGEST THAT GRADIENT WILL BE ROUGHLY LOCATED ALONG THE KS/OK
BORDER, WHICH WILL LEAD TO NOCTURNAL CONVECTION ALONG OR NORTH OF
THIS BOUNDARY BOTH TUES AND WED NIGHT AS LOW LEVEL JET INCREASES.
SO WILL PLACE 30-35 CHANCE POPS IN SRN SECTIONS OF KANSAS, EACH
NIGHT.  GFS/ECMWF SEEMS TO PUSH THE BOUNDARY FURTHER SOUTH WITH EACH
NIGHTS CONVECTION, SO WILL END POPS FOR THU WITH WEAK RIDGING ACROSS
KS. TEMPS AND CLOUDS WILL BE VERY DEPENDENT ON CLOUDS/MCS ACTIVITY,
SO ADJUSTED MAX TEMPS DOWN SOME TO REFLECT THIS.

FRI-SAT:
END OF THE EXTENDED IS RATHER UNCERTAIN AS MED RANGE MODELS NOT
HANDLING THIS TIME FRAME VERY WELL.  GFS HINTS THAT BOUNDARY MAY
DRIFT BACK NORTH DURING THIS FRAME, LEADING TO MORE NOCTURNAL
CONVECTION.  WILL INSERT A LOW POP FOR FRI NIGHT FOR MAINLY
CONSISTENCY SAKE.

HAZARDOUS WEATHER OUTLOOK...UPDATED

659 PM CDT SAT MAY 21 2005

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL AND SOUTHEAST KANSAS.

.DAY ONE...TONIGHT

A FEW THUNDERSTORMS WILL CONTINUE TO DEVELOP OVER CENTRAL KANSAS
MAINLY SOUTHEAST OF A RUSSELL TO LINCOLN LINE DURING THE EARLY
EVENING. A STORM OR TWO MAY BECOME SEVERE AND PRODUCE DAMAGING WIND
GUSTS TO 60 MPH. MORE THUNDERSTORMS ARE FORECAST TO DEVELOP THIS
EVENING IN NORTHEAST KANSAS, THEN EXPAND AND MOVE SOUTH INTO
SOUTHEAST KANSAS LATE THIS EVENING OR SHORTLY AFTER MIDNIGHT. THE
MAIN AREA OF CONCERN WILL BE ALONG OR EAST OF THE FLINT HILLS FROM
SALINA TO INDEPENDENCE. ANY STORMS THAT CAN DEVELOP DURING THE
OVERNIGHT HOURS COULD BE SEVERE WITH LARGE HAIL AND DAMAGING WINDS
THE MAIN THREAT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THUNDERSTORMS MAY BE ONGOING SUNDAY MORNING, MAINLY SOUTH OF HIGHWAY
400.  THE THREAT OF THUNDERSTORMS WILL PERSIST ALL DAY ALONG THE
KANSAS OKLAHOMA BORDER.  THE STORMS COULD BE SEVERE ALONG THE
OKLAHOMA BORDER IN THE AFTERNOON.

THE WEATHER PATTERN FOR TUESDAY THROUGH THURSDAY SUGGESTS SOME
POSSIBILITY OF THUNDERSTORMS VIRTUALLY EVERY NIGHT.  WARM AIR AND
MOISTURE RETURNING NORTH WILL RESULT IN A STATIONARY FRONT SOMEWHERE
ACROSS THE PLAINS DURING THE WEEK.  THUNDERSTORMS WILL LIKELY
DEVELOP AND TRACK ALONG THIS FRONT DURING THE EVENING AND OVERNIGHT
HOURS. AT THIS POINT, THERE APPEARS TO BE A SLIGHTLY BETTER CHANCE
OF THUNDERSTORMS ON WEDNESDAY.  WHILE SEVERE WEATHER IS LIKELY
SOMETIME DURING THE WEEK, IT IS DIFFICULT TO DELINEATE THE THREAT,
AREAS OR TIMING AT THIS POINT.

.SPOTTER INFORMATION STATEMENT...

SKYWARN SPOTTER ACTIVATION MAY BE REQUIRED OVERNIGHT EAST OF A LINE
FROM SALINA TO CHANUTE.
