Hail and Damaging Winds in Kansas, June 21, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
320 PM CDT WED JUN 21 2006

.DISCUSSION...
CONCERNS TODAY WILL BE SEVERE CHANCES THIS EVENING/OVERNIGHT THAN
PRECIP CHANCES AGAIN THU.

THIS EVE AND TNGT:
INSTABILITY (SBCAPES OF 3500-4000 J/KG) AND UPPER 60S SURFACE
DEWPOINTS CONTINUE TO POOL ALONG SURFACE TROF AND REMNANTS OF THE
STATIONARY BOUNDARY LOCATED FROM DDC TO HYS TO CNK. SB CIN CONTINUES
TO WEAKEN...WITH CONVECTION EXPECTED NEAR THIS BOUNDARY BY THE
LATE AFTERNOON OR EARLY THIS EVENING WITH RUC SHOWING FN-CONVERGENCE
MAXIMIZED NEAR THE BOUNDARY.  INSTABILITY AND 0-6KM SHEAR OF 30-35KT
SUGGEST STORMS COULD BECOME SEVERE WITH THE MAIN THREAT BEING
DAMAGING WINDS AS FORECAST SOUNDINGS SUGGEST AN INVERTED V SOUNDING
WITH DRIER LAYERS NEAR THE SURFACE. SO WILL CONTINUE THIS MENTION IN
THE GRID/ZONES.

DAMAGING WIND THREAT MAY CONTINUE INTO THE EARLY PORTION OF THE
OVERNIGHT HOURS AS CORFIDI VECTORS SUGGEST CONVECTION EVOLVING INTO
A CONVECTIVE COMPLEX AND PROPAGATING SLOWLY TO THE SE TOWARDS ICT AS
THE OVERNIGHT PROGRESSES. WILL GO CATEGORICAL POPS FOR AREA FROM ICT
NORTHWESTWARD FOR THIS CHANCE.

THU:
EXPECT CONVECTION TO BE ONGOING DURING THE MORNING HOURS...
(ESPECIALLY OVER SRN/SERN KS) AS REMNANTS OF OVERNIGHT CONVECTION
FORMS MORE OF AN MCV THAT WILL MOVE ACROSS SERN KS INTO SWRN MO. SO
WILL GO WITH LIKELY POPS AS THIS MCV MOVES ACROSS THE AREA.

NEXT CONCERN WILL BE AMOUNT OF RECOVERY THAT WILL OCCUR FOR THE
AFTERNOON HOURS AS OVERNIGHT CONVECTION PUSHES THE SURFACE BOUNDARY
INTO SRN KS. LOTS OF INSTABILITY AGAIN WILL POOL ALONG THIS BOUNDARY
WITH THUNDERSTORMS AGAIN POSSIBLE FOR THU EVE/NIGHT.  WILL KEEP
CHANCE POPS IN MOST LOCATIONS AS 850H BOUNDARY REMAINS A LITTLE
FURTHER NORTH THAN THE SURFACE BOUNDARY WITH MOISTURE TRANSPORT
MAXIMIZED ACROSS THE AREA AS LOW LEVEL JET AGAIN INCREASES.

FRI:
COULD SEE SOME MORNING REMNANTS AGAIN ACROSS THE AREA EARLY ON
FRI...ESPECIALLY IN SRN KS (FURTHER SOUTH THAN THU MORNINGS).  WEAK
RIDGING ALOFT AND AT THE SURFACE MOVES IN FOR THE AFTERNOON AND
NIGHTIME HOURS.  SO WILL REDUCE POPS FROM NW TO SE AS THE DAY
PROGRESSES...WITH CLEARING SKIES POSSIBLE BY THE LATE AFTERNOON
HOURS IN CEN KS.

SAT-SUN:
THIS IS A RATHER UNCERTAIN TIME FRAME AS MODELS DIVERGE ON SOLUTIONS
FOR SAT INTO SUN.  UPPER FLOW PATTERN DOES GO MORE NW WITH
TIME...WITH GFS ACTUALLY SHOWING SOME WEAK RIDGING ACROSS THE AREA
FOR SAT.  THIS MODEL ALSO SHOWS A WEAK COLD FRONTAL BOUNDARY MAKING
ITS WAY ACROSS ERN NEBRASKA BY SAT NIGHT...WITH SOME CONVECTION
POSSIBLY MOVING ACROSS NERN KS. HAVE REMOVED POPS FOR MOST OF SAT
WITH THIS IN MIND...AS EVEN THE ECMWF ALSO DRIES THINGS OUT IN THE
LOW LAYERS ACROSS THE AREA FOR SAT.

WILL KEEP THE POPS IN PLACE FOR SUN AS GFS ADVERTISES THE WEAK
BOUNDARY IN NEBRASKA DROPPING ACROSS CEN KS BY THE AFTERNOON HOURS.
NOT ALOT OF UPPER LEVEL SUPPORT FOR WIDESPREAD CONVECTION...BUT
ENOUGH CONVERGENCE AND LOW LEVEL MOISTURE IN PLACE AHEAD OF THE
BOUNDARY TO WARRANT A LOW POP.

MON-WED:
NW UPPER LEVEL FLOW BECOMES MORE DIFFLUENT AS THE BEGINNING OF NEXT
WEEK STARTS...WITH UPPER RIDGE IN THE ROCKIES ACTUALLY RETROGRADING
TO THE WEST SOME.  THIS WILL ALLOW PROBABLY ALLOW NOCTURNAL
CONVECTION TO AGAIN BECOME THE MAIN WEATHER MAKERS FOR TUE INTO WED
AS LOW LEVEL JET AGAIN SETS UP ACROSS THE PLAINS.  MED RANGE GFS
HINTS AT THIS FOR TUE NIGHT INTO WED FOR PORTIONS OF SRN NE/NRN KS.
WILL NOT BITE ON THIS JUST YET...AS MCS TYPE SYSTEMS ARE HARD TO
PIN DOWN THIS FAR OUT.
