AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
900 PM CDT FRI MAY 4 2007

.MESO UPDATE...
SUPERCELLS (LEFT AND RIGHT MOVERS) CONTINUE TO MOVE/DEVELOP
NORTHEAST...WEST AND NORTH OF THE FORECAST AREA. SUPERCELLS WEST
OF THE FORECAST AREA SHOULD CONTINUE TO PROGRESS NORTHEAST AS THEY
MOVE INTO A MORE UNSTABLE AIRMASS. AMPLE LOW-LEVEL WIND SHEAR AND
RELATIVELY WEAK CONVECTIVE INHIBITION SHOULD POSE A CONTINUED
TORNADO THREAT THROUGH THE NEXT 2-3 HOURS...MAINLY WITH
RIGHT-MOVING SUPERCELLS.

KLEINSASSER

&&

.PREV DISCUSSION... /ISSUED 709 PM CDT FRI MAY 4 2007/

MESO UPDATE...
TORNADO WATCH ISSUED UNTIL 2 AM FOR COUNTIES WEST OF I-135...NOT
INCLUDING WICHITA. CURRENTLY MONITORING TWO SUPERCELLS (RIGHT AND
LEFT MOVERS) PROGRESSING NORTHEAST ACROSS NORTHWEST
OKLAHOMA...THAT ARE NOW PROGRESSING WELL AWAY FROM THE DRYLINE.
GIVEN WEAK CONVECTIVE INHIBITION AMONGST VERY UNSTABLE
AIRMASS...DONT SEE ANY REASON FOR THESE CELLS TO NOT CONTINUE
PROGRESSING NORTHEAST AS THEY ENCOUNTER RICHER LOW-LEVEL
MOISTURE...AND MAYBE EVENTUALLY INTO SOUTHWEST PORTIONS OF THE
FORECAST AREA BY 9-10PM. ADDITIONALLY...MAY STILL SEE DEVELOPMENT
THIS EVENING FROM ROUGHLY HILL CITY THROUGH HAYS/RUSSELL AND GREAT
BEND. HOWEVER...THIS SCENARIO IS LOOKING A BIT LESS LIKELY AS
REGIONAL RADAR MOSAIC INDICATES A RETREATING DRY LINE...BUT THEY
ARENT OUT OF THE WOODS YET. REGARDLESS...INCREASING DEEP AND
LOW-LEVEL SHEAR BETWEEN 7-10 PM DUE TO BACKING SURFACE FLOW AND
INCREASING LOW-LEVEL JET SHOULD ENHANCE THE TORNADO THREAT
THROUGH 10 PM WITH ANY STORMS ACROSS THE AREA. WILL CONTINUE TO
MONITOR.

KLEINSASSER

AVIATION...
THUNDERSTORMS MAY EVENTUALLY MOVE/DEVELOP NORTHEAST INTO PORTIONS
OF CENTRAL AND SOUTH-CENTRAL KANSAS THIS EVENING. STILL TOO FAR
AWAY TO REALLY TIME OUT EXACTLY...HENCE VCTS WORDING FOR NOW.
OTHERWISE...ANTICIPATING IFR CEILINGS AND MVFR VISIBILITIES TO
ONCE AGAIN EVENTUALLY DEVELOP AFTER 06Z...AS DIURNAL COOLING SETS
IN. HOWEVER...WOULD BE SURPRISED TO SEE LIFR CONDITIONS...AS
BOUNDARY LAYER MIXING IS MUCH STRONGER TONIGHT THAN LAST NIGHT.
WILL MAKE TIMELY AMENDMENTS IF/WHEN NECESSARY.

KLEINSASSER

PREV DISCUSSION... /ISSUED 316 PM CDT FRI MAY 4 2007/

DISCUSSION...

THE MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE WHERE THE FOCUS
OF CONVECTION WILL BE TONIGHT AND WHERE THE BEST CHANCES OF STORMS
WILL BE DURING THE REMAINDER OF THE WEEK.

TONIGHT:
LATEST VISIBLE IMAGERY AND SURFACE ANALYSIS SHOWING SEVERAL FOCUS
MECHANISMS THAT MAY PLAY A ROLE IN DEVELOPING CONVECTION LATE THIS
AFTERNOON. THE FIRST ONE IS JUST NOW GOING THROUGH WICHITA WITH THE
FLOW TURNING TO THE EAST ONCE THE BOUNDARY PASSES THROUGH. THIS
BOUNDARY IS MOVING THROUGH A RIPE ENVIRONMENT WITH CAPE VALUES
APPROACHING 3000J/KG. SHEAR PROFILES ARE ALSO VERY FAVORABLE FOR
SUPERCELLS WITH TORNADOES...BUT WE STILL HAVE ABOUT 80-100J/KG OF
CONVECTIVE INHIBITION. THE SECOND OBVIOUS FOCUS MECHANISM IS ACROSS
NORTHWEST KANSAS WHERE THE SURFACE BOUNDARY/DIFFERENTIAL HEATING
BOUNDARY CONTINUES TO LIFT NORTH. THIS AREA MAY END UP BEING THE
MOST ORGANIZED TONIGHT. LATEST WATER VAPOR LOOP/PROFILER DATA IS
ALSO SHOWING ABOUT 70-80KT JET STREAK MOVING THROUGH THE TEXAS
PANHANDLE. LATEST SURFACE ANALYSIS IS ALSO SHOWING THE DRY LINE
BECOMING VERY WELL DEFINED ACROSS SOUTHWEST KANSAS WITH MINIMAL
CONVECTIVE INHIBITION. THIS AREA IS ALSO UNDER THE INFLUENCE OF GOOD
DIFFLUENCE...WHICH COULD BE A FOCUS FOR SOME ISOLATED SUPERCELLS. WE
WILL HAVE WATCH THIS AREA THIS EVENING...BECAUSE ANY RIGHT MOVERS
WOULD AFFECT CENTRAL OR SOUTH CENTRAL KANSAS. WE HAVE LOWERED POPS
TONIGHT SINCE THE MAIN FOCUS LOOKS TO BE IN NORTHWEST KANSAS
TONIGHT. OTHERWISE...WE MAY SEE SOME MORE STRATOCUMULUS
REDEVELOPING DUE TO A GOOD STRONG LOW LEVEL JET.

SATURDAY-SATURDAY NIGHT:
THERE MAY BE A FEW SHOWERS OR STORMS IN THE MORNING IN CENTRAL
KANSAS DUE TO SOME MODEST MOISTURE TRANSPORT/ISENTROPIC
LIFT...ESPECIALLY IF THERE IS ANY LINGERING BOUNDARIES.
OTHERWISE...WE SHOULD SEE GOOD MIXING TAKE PLACE THROUGH THE DAY
WITH MOMENTUM TRANSFER VALUES POSSIBLY EXCEEDING 30KTS WHICH WILL BE
FAVORABLE FOR MOST OF US TO REACH WIND ADVISORY CRITERIA. WE ARE NOT
TOO KEEN ON CONVECTION CHANCES OVER OUR AREA...ESPECIALLY SINCE
THERE IS REALLY NO FOCUS MECHANISM TO KEY ON IN OUR FORECAST AREA.
WE HAVE BACKED OFF ON POPS SLIGHTLY TO REFLECT THIS. HOWEVER...WE
MAY HAVE TO WATCH WHEN THE CONVECTION FIRES ALONG THE DRY LINE. THE
REMAINDER OF THE NIGHT...WE WILL HAVE TO SEE HOW THINGS EVOLVES.
RIGHT NOW...WE BELIEVE THAT ANY OF THE SUPERCELL STORMS THAT GET
GOING ALONG THE DRY LINE MAY EVOLVE INTO A CLUSTER AND MOVE THROUGH
THE WESTERN SECTIONS OF THE FORECAST AREA DURING THE EVENING AND
OVERNIGHT WITH THE POTENTIAL FOR LARGE HAIL AND HIGH WINDS. WE WILL
HAVE A BETTER HANDLE ON THIS AS TIME GETS CLOSER.

SUNDAY-MONDAY:
THIS TIMEFRAME WILL BE HIGHLY DEPENDENT ON WHAT TAKES PLACE SATURDAY
NIGHT WITH ANY LINGERING OUTFLOW BOUNDARIES. THE MODELS ARE
GENERALLY IN AGREEMENT IN SHOWING THE SYNOPTIC BOUNDARY SETTING UP
OVER CENTRAL KANSAS. THIS BOUNDARY COULD SERVE AS A FOCUS FOR MORE
AREAS OF CONVECTION ON SUNDAY AND SUNDAY NIGHT. WE HAVE RAISED POPS
DURING THIS TIMEFRAME TO REFLECT THIS POTENTIAL. ON MONDAY THE
ECMWF/UKMET/GFS ARE ADVERTISING THE FRONTAL BOUNDARY SHIFTING
THROUGH THE FORECAST AREA DURING THE DAY WHICH COULD LIMIT OUR
CONVECTION CHANCES. WE HAVE KEPT OUR POPS ON THE CHANCE SIDE TO
REFLECT THIS.

TUESDAY-FRIDAY:
THE UPPER LEVEL TROF WILL CONTINUE HANG OVER THE NORTHERN ROCKIES AT
LEAST THROUGH WEDNESDAY. AS A RESULT...WE HAVE NOT MADE MANY CHANGES
AND KEPT OUR CHANCES OF THUNDERSTORMS IN THE PICTURE. THE MODELS ARE
SHOWING SOME UPPER LEVEL RIDGING TAKING PLACE LATE NEXT WEEK WHICH
MAY GIVE US A BREAK FROM THE RAIN.

AVIATION...

MVFR CONDITIONS ARE EXPECTED THROUGH THE EVENING HOURS TONIGHT. THE
BEST CHANCES FOR CONVECTION TO DEVELOP WILL BE ALONG AN AREA OF
CONVERGENCE NEAR HAYS AND DODGE CITY...AND THESE STORMS WOULD
PROPAGATE NORTHEASTWARD. THESE STORMS COULD AFFECT KRSL AND KGBD
THIS EVENING...WHILE OTHER SITES REMAIN DRY.

CEILINGS SHOULD LOWER TO IFR AND PERHAPS LIFR TONIGHT TOWARD
MIDNIGHT. SURFACE WINDS WILL REMAIN GUSTY OVERNIGHT AND THROUGH THE
DAY SATURDAY...ESPECIALLY OVER CENTRAL AND SOUTH CENTRAL KANSAS WITH
A STRONG JET OVER THE FORECAST AREA.
