AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
654 PM CDT MON MAY 24 2010

.UPDATE...

SENT OUT A QUICK UPDATE TO TRIM BACK THE EASTERN EXTENT OF PRECIP
BEFORE 06Z BASED MOSTLY ON RADAR TRENDS. ALSO WENT AHEAD AND
DECREASED CLOUD COVER AREA WIDE TO KEEP UP WITH CURRENT TRENDS.

&&

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

MAIN AVIATION CONCERN WILL BE STORM CHANCES THROUGH THE NEXT 24
HOURS.

STRONG UPPER TROUGH IS NOW LIFTING OUT ACROSS WESTERN NEBRASKA/SW SD
WITH THE DRYLINE STILL LINGERING BACK ACROSS FAR WESTERN KS. STORMS
HAVE INCREASED IN COVERAGE ACROSS WESTERN KS OVER THE LAST COUPLE OF
HOURS AS LARGE SCALE LIFT INCREASED SLIGHTLY. THE BULK OF THIS
ACTIVITY IS EXPECTED TO STAY WEST OF THE FORECAST AREA THROUGH 03Z.
KRSL WILL HAVE THE BEST SHOT TO EXPERIENCE A STORM BETWEEN THE
03Z-06Z TIME FRAME. THE SURFACE FRONT IS EXPECTED TO SHIFT SLIGHTLY
SOUTHEAST FOR TUE WHICH WILL BRING INCREASED STORM CHANCES TO
CENTRAL KS WITH KSLN AND KRSL HAVING THE BEST SHOT TO EXPERIENCE A
STORM WITH THE SURFACE BOUNDARY SITUATED CLOSER TO THESE AREAS.
HOWEVER WITH PLENTY OF INSTABILITY AND AN UNCAPPED AIRMASS...A STRAY
STORM WILL BE POSSIBLE AREA WIDE BY TUE AFTERNOON. WITH CONFIDENCE
LOW ON ARAL COVERAGE...WILL NOT HIT CONVECTIVE CHANCES TOO HARD YET
FOR TUE AFTERNOON.

.PREV DISCUSSION... /ISSUED 319 PM CDT MON MAY 24 2010/

DISCUSSION...

SYNOPSIS...SATELLITE/OBSERVATION LOOP ENDING AT 1930Z SHOWS AN UPPER
LOW /500 MB/ CENTERED OVER THE CENTRAL ROCKIES.  A DRYLINE EXTENDS
FROM NEAR KLBL TO KSNY.  STORMS AHEAD OF THIS DRYLINE NOW IN
PROGRESS.  SEVERAL OF THESE ARE SEVERE.

EFFECTIVE DEEP LAYER SHEAR SHOWING ABOUT 40 KNOTS SUPPORTING
SUPERCELLS.  ENOUGH 0-3KM MIXED LAYER CAPES/0-1KM HELICITY AND
DEWPOINT DEPRESSIONS RUNNING AROUND 9 DEGREES /F/ TO PRODUCE A
FAVORABLE ENVIRONMENT FOR TORNADOES.

TONIGHT-WEDNESDAY:
THE MAIN FORECAST PROBLEM IS THE LOCATION AND TIMING OF CONVECTION.
12Z/15Z/18Z MODEL RUNS SHOW A VARIETY OF SOLUTIONS WITH RESPECT TO
HOW FAR THE COLD FRONT MOVES INTO THE STATE AND POSSIBLY OR
CONVECTION.  I THINK CONSENSUS RIGHT NOW IS TO EXPECT THE COLD FRONT
TO STALL IN NORTH-CENTRAL KANSAS.  THIS WILL CAUSE THE CONVECTION TO
MOVE SOUTHEAST INTO THE FORECAST AREA WITH THE BEST CHANCE BY
12Z-15Z TOMORROW MORNING FOR PRECIPITATION TO BE ALONG AND JUST WEST
OF THE I-35 CORRIDOR.

SHEAR/BUOYANCY RELATIONSHIPS SHOW A FAVORABLE ENVIRONMENT FOR
SUPERCELLS ACROSS THE NORTHWESTERN HALF OF THE FORECAST AREA.
HOWEVER...AFTER TUESDAY...THE UPPER LEVEL RIDGE MOVES IN AND THERE
APPEARS TO BE VERY LITTLE CHANCE OF ORGANIZED CONVECTION UNTIL THE
RIDGE WEAKENS.

FROM THAT POINT FORWARD...THERE ARE SO MANY OUTFLOWS...CONVECTIVELY
INDUCED PV ANOMALIES...AND WEAK DISTURBANCES IN THE FLOW THAT WE
USED AN ENSEMBLE APPROACH VIA THE SREF.

THE PLUME DIAGRAMS FOR KRSL/KICT/KCNU SHOW A CONSISTENT SIGNAL
TODAY/TUESDAY/WEDNESDAY...WITH CONVECTION DEVELOPING ACROSS THE
FORECAST AREA FROM THE 15Z-18Z TIME PERIOD AND PERSISTING UNTIL
ABOUT 03Z.

THURSDAY-MONDAY:
THE 5 DAY MEAN OF THE 500MB HEIGHT FORECASTS SHOW A GRADUAL
RETROGRESSION AND WEAKENING OF THE UPPER LEVEL RIDGE THROUGH
TIME...EVOLVING INTO A ZONAL FLOW PATTERN NEXT WEEK.  GEFS MODEL
UNCERTAINTY IS WELL BELOW CLIMATOLOGY FOR THIS TIME OF YEAR...SO THE
GEFS SHOULD DO A GOOD JOB WITH THE FORECAST.  I WILL SAY THAT WE
RESISTED THE URGE TO INTRODUCE PRECIPITATION CHANCES EVERY DAY...DUE
TO THE LOW PREDICTABILITY OF CONVECTIVE FORCING FEATURES DURING THIS
TIME FRAME.  TEMPERATURES SHOULD TREND NEAR OR JUST ABOVE NORMAL.
