AREAS AFFECTED...SOUTH CENTRAL KS INTO PARTS OF NRN AND CENTRAL OK

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 301957Z - 302100Z

ADDITIONAL TSTM DEVELOPMENT IS EXPECTED BETWEEN 20-22Z INVOF A COLD
FRONT ADVANCING SLOWLY E/SEWD THROUGH CENTRAL KS AND WRN OK THIS
AFTERNOON. ISOLATED HAIL AND STRONG WIND GUSTS WILL BE THE PRIMARY
THREATS WITH THIS ACTIVITY...WHILE A NON-ZERO TORNADO THREAT DOES
EXIST. POTENTIAL FOR STRONG-SEVERE STORM COVERAGE MAY BE LOW WHICH
IS RESULTING IN AN UNCERTAINTY FOR THE ISSUANCE OF A SEVERE WEATHER
WATCH. HOWEVER...CONVECTIVE TRENDS WILL BE MONITORED FOR POTENTIAL
WW ISSUANCE THROUGH THE LATE AFTERNOON.

19Z SURFACE ANALYSIS SHOWED A COLD FRONT EXTENDING FROM NW OF TOP
SWWD INTO SOUTH CENTRAL KS /THROUGH KINGMAN COUNTY/ TO WRN OK. A
SURFACE LOW WAS LOCATED OVER NWRN OK WITH A DRY LINE EXTENDING SEWD
FROM THE LOW/TRIPLE POINT THROUGH CENTRAL AND SRN OK /OR JUST WSW OF
OKC-OUN-ADM LINE/. SURFACE OBSERVATIONS INDICATED WINDS ACROSS THE
WARM SECTOR HAVE RECENTLY BACKED TO SELY...RESULTING IN INCREASED
LOW LEVEL CONVERGENCE ALONG THE COLD FRONT IN SOUTH CENTRAL KS/NORTH
CENTRAL-NWRN OK. THIS IS VERIFIED BY AN INCREASE IN CU/TCU FIELD
ALONG THE FRONT IN SOUTH CENTRAL KS TO NWRN OK SINCE 18Z...WITH ICT
WSR-88D SHOWING AN INCREASE IN REFLECTIVITY OVER KINGMAN COUNTY.
DESPITE WEAK FORCING ALOFT...TSTMS ARE EXPECTED TO DEVELOP AND
INCREASE SOME IN COVERAGE AS THE COLD FRONT SPREADS FURTHER SEWD
INTO OK. SBCINH HAS BEEN ELIMINATED ACROSS MUCH OF THE WARM SECTOR
SUPPORTING TSTM DEVELOPMENT. WEAK DEEP LAYER SHEAR SHOULD LIMIT
SUPERCELL DEVELOPMENT...THOUGH MULTICELLS WILL BE POSSIBLE. STEEP
LAPSE RATES WITH MIDLEVEL VALUES AROUND 8 C/KM AND MLCAPE VALUES
2000-3000 J/KG WILL SUPPORT HAIL AND STRONG WIND GUSTS AS THE
PRIMARY THREATS. ALTHOUGH LOWER TROPOSPHERIC WIND FIELDS ARE RATHER
WEAK...BACKED SELY WARM SECTOR SURFACE WINDS BENEATH WLY MID LEVEL
WINDS MAY SUPPORT A NON-ZERO TORNADO THREAT...GIVEN DIRECTIONAL
SHEAR.

CONFIDENCE IN ADDITIONAL TSTM DEVELOPMENT ACROSS THE DISCUSSION AREA
IS INCREASED BY MODEL ANALYSIS. HOWEVER...OVERALL COVERAGE SHOULD
BE SOMEWHAT LIMITED SPATIALLY. SPECIFICALLY...THE 15Z WRF-HRRR AND
12Z NAM/15Z SREF ETA-KF CONTROL MEMBER INDICATED TSTM DEVELOPMENT
ALONG THE COLD FRONT OVER SOUTH CENTRAL KS INTO NORTH-CENTRAL/NWRN
OK BETWEEN 20-22Z...WITH ACTIVITY DEVELOPING/SPREADING SEWD INTO OK
TO ALONG THE I-44 CORRIDOR BETWEEN 00-01Z FROM TUL TO FSI.

NWS STORM PREDICTION CENTER NORMAN OK
0246 PM CDT SUN MAY 30 2010

VALID 302000Z - 311200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF CNTRL/NCNTRL
OK AND SCNTRL/SERN KS...

ONLY APPRECIABLE CHANGE TO ONGOING FORECAST: BETTER DEFINE WRN EDGE
OF SLIGHT RISK OVER OK.

...KS/OK...
19Z MESOANALYSIS PLACES A MESOLOW OVER NWRN OK WITH A COLD FRONT N
THROUGH KP28-KOMA AND S TO KCSM-KLBB THEN ARCING NWWD ALONG THE NM
HIGH PLAINS.

CONVECTIVE INITIATION OCCURRING OVER KS ALONG THE FRONT WILL
CONTINUE SWWD IN A ZIPPER-LIKE FASHION INTO NWRN OK IN THE 20-22Z
TIME FRAME AMIDST MLCAPES 2000-3000 J/KG. STRONG DEEP LAYER SHEAR
EXISTS ALONG COOL SIDE OF THE FRONT...BUT MAGNITUDE OF LAPSE RATES
WILL RESULT IN VIGOROUS UPDRAFTS AND THE POSSIBILITY OF LARGE HAIL
AND HIGH WINDS WITH MULTICELLS/BRIEF SUPERCELL STRUCTURES. ACTIVITY
WILL LIKELY CONGEAL INTO A LOOSELY-ORGANIZED MCS AND LINGER OVER
SERN KS AND NCNTRL/CNTRL OK LATER IN THE EVENING...POSSIBLY
BACKBUILDING ALONG SWRN FLANKS OVERNIGHT. SVR THREATS SHOULD
GRADUALLY WANE AFTER 03Z OR SO.

REMAINDER OF THE FORECAST UNCHANGED./RACY

..RACY/HALES/JEWELL.. 05/30/2010

.PREV DISCUSSION... /ISSUED 1120 AM CDT SUN MAY 30 2010/

EVOLVING ZONAL FLOW MUCH OF CONUS AS COLD UPPER SYSTEM SHIFTS INTO
SRN CANADA AND HEIGHTS GENERALLY RISE OVER THE CENTRAL U.S. WEAK
STALLED CUT-OFF LOW OVER MS WILL BEGIN DRIFTING NEWD AND WEAKEN
FURTHER.

COLD FRONT TRAILING SWWD FROM SURFACE LOW NRN MN THRU WRN IA TO NWRN
OK AND ERN NM WILL BE THE FOCUS FOR THE RATHER LOW END SEVERE
CONCERN TODAY.

...KS/OK...
A MOIST AND MDTLY UNSTABLE WARM SECTOR IS IN PLACE ACROSS KS/OK IN
ADVANCE OF THE COLD FRONT. DAYTIME HEATING WILL RAISE SURFACE TEMPS
TO NEAR OR ABOVE 90F BY MID AFTERNOON WHICH EFFECTIVELY REMOVES THE
CONVECTIVE INHIBITION AND RESULTS IN MLCAPES AOA 2000 J/KG.

SCATTERED THUNDERSTORMS WILL DEVELOP VICINITY FRONTAL ZONE FROM ERN
KS SWWD INTO SWRN OK BY MID/LATE AFTERNOON AND MOVE/PROPAGATE RATHER
SLOWLY E/SEWD THRU THE EVENING. AS THE SHEAR PROFILES DROP BELOW
ABOUT 20KT THE PRIMARY MECHANISM FOR SEVERE STORMS WILL BE THE
COMBINATION OF RELATIVELY STEP MID LEVEL LAPSE RATES...AOA
7C/KM...AND THE UNSTABLE AIR MASS. STRONGEST UPDRAFTS SHOULD SUPPORT
LARGE HAIL AND LOCAL DAMAGING DOWNBURST WINDS.

ANY SEVERE THREAT SHOULD DIMINISH QUICKLY WITH LOSS OF HEATING BY
THIS EVENING.

...MN/WI...
A SHORTWAVE TROUGH PROGRESSING EAST NORTHEASTWARD ACROSS THE
NORTHERN PLAINS/UPPER MS VALLEY TODAY WILL HELP TO INITIATE ISOLATED
AFTERNOON THUNDERSTORMS ACROSS PARTS OF MN/WI/IA...AGAIN VICINITY OF
THE COLD FRONT. MODEL SOLUTIONS SUGGEST CONVECTION WILL BE
ISOLATED...AND FORECAST SOUNDINGS SHOW WEAK MID LEVEL LAPSE RATES
AND CAPE. A FEW INTENSE STORMS CAPABLE OF GUSTY WINDS AND HAIL ARE
POSSIBLE...BUT ORGANIZED SEVERE ACTIVITY IS NOT PRESENTLY
ANTICIPATED.

...SOUTHEAST...
A WEAK UPPER LOW REMAINS OVER MS THIS MORNING...WITH AMPLE LOW AND
MID LEVEL MOISTURE SURROUNDING THE SYSTEM. THUNDERSTORMS ARE
EXPECTED TO DEVELOP ONCE AGAIN BY EARLY AFTERNOON...ESPECIALLY TO
THE EAST OF THE LOW CENTER ACROSS PARTS OF MS/AL/TN/GA. THE MID
LEVEL COLD POOL HAS BEEN SLOWLY WARMING WITH THIS
SYSTEM...SUGGESTING A DECREASING HAIL THREAT. NEVERTHELESS...A FEW
STORMS CAPABLE OF GUSTY/DAMAGING WINDS REMAIN POSSIBLE.

1228 PM CDT SUN MAY 30 2010

VALID 311200Z - 011200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS A SMALL PART OF THE
CENTRAL AND SOUTHERN HIGH PLAINS...

...SYNOPSIS...
THE UPPER FLOW REGIME WILL BECOME MORE ZONAL ON MONDAY AS THE WRN
STATES TROUGH TOPS THE UPPER RIDGE AND CONTINUES DOWNSTREAM ALONG
THE NRN TIER OF THE COUNTRY. THE ASSOCIATED COLD FRONT CURRENTLY
OVER THE PLAINS WILL MOVE THROUGH THE GREAT LAKES REGION...REACHING
THE NERN STATES BY MONDAY NIGHT. TAIL-END OF THE BOUNDARY WILL
SUBSEQUENTLY REDEVELOP NWD AS A WARM FRONT INTO THE CNTRL PLAINS. A
NEW COLD FRONT IS FORECAST TO MORE SEWD THROUGH THE NRN
PLAINS...REACHING THE UPPER MS VALLEY BY MONDAY NIGHT.

...CNTRL HIGH PLAINS AREA...
FORECAST UNCERTAINTY IS HIGH WITH FRONT/OUTFLOW BOUNDARY PLACEMENTS
BY MONDAY AFTERNOON. SHORT-TERM MODELS/ENSEMBLES ARE CLUSTERING
AROUND THE SOLUTION THAT BOUNDARY LAYER SELYS WILL INCREASE MONDAY
AFTERNOON IN WAKE OF MORNING CONVECTION AND THE WARM FRONT SHOULD
DEVELOP QUICKLY NWD INTO NRN OK/SRN KS. MEANWHILE...A WEAK LEE
TROUGH WILL BECOME ESTABLISHED OVER FAR ERN CO AND NM AMIDST ZONAL
FLOW ALOFT AND A TRIPLE POINT SHOULD EVOLVE OVER SERN CO/NERN NM.

A RESERVOIR OF MODEST MOISTURE WILL BE TRANSPORTED NW TO THE TRIPLE
POINT WITH LOWER/MIDDLE 60S SURFACE DEW POINTS ACROSS WRN/CNTRL
KS/OK AND NEAR 50F INTO EXTREME ERN CO/NM. THE MOISTURE WILL RESIDE
BENEATH STEEP LAPSE RATES AND STRONG DIABATIC HEATING WILL
CONTRIBUTE TO 1500-2500 J/KG MLCAPE BY MID-AFTERNOON. BUILDING
HEIGHTS AND STRENGTH OF THE ELEVATED MIXED LAYER WILL PROBABLY
MAINTAIN A SIZABLE CAP IN THE LOWER PLAINS THROUGH THE AFTERNOON.
BUT...HIGH-BASED STORMS ARE EXPECTED TO FORM ALONG THE HIGHER SERN
CO/NERN NM TERRAIN AND ALONG THE LEE TROUGH/DRYLINE/TRIPLE POINT BY
LATE AFTERNOON. ADDITIONAL STORMS MAY FORM NEAR/AFTER SUNSET
ALONG/NORTH OF THE WARM FRONT ACROSS CNTRL/SRN KS AS THE LOW-LEVEL
JET STRENGTHENS DURING THE EVENING.

EFFECTIVE VERTICAL SHEAR WILL BE SUFFICIENT FOR SUPERCELLS...
ESPECIALLY WITH THE INITIAL STORMS OVER THE HIGHER PLAINS. BUT...AS
THE EVENING APPROACHES...EVOLUTION INTO ONE OR MORE MESOSCALE
CONVECTIVE COMPLEXES COULD OCCUR...MOST LIKELY OVER SWRN KS/NWRN OK
EWD TOWARD CNTRL/ERN KS. ISOLATED LARGE HAIL AND HIGH WINDS WILL BE
THE PRIMARY THREATS.

...NEB AND SD...
THE ATMOSPHERE WILL DESTABILIZE NWD THROUGH THE PLAINS ALONG AXIS OF
THETA-E ADVECTION ASSOCIATED WITH THE STRENGTHENING LOW LEVEL JET.
ELEVATED STORMS COULD DEVELOP OVERNIGHT WITHIN THE ZONE OF
INCREASING ISENTROPIC LIFT. MODERATE INSTABILITY...STEEP MID LEVEL
LAPSE RATES...AND EFFECTIVE SHEAR OF 40 KT WILL SUPPORT A THREAT FOR
ISOLATED LARGE HAIL.

...LOWER GREAT LAKES THROUGH PORTIONS OF NERN STATES...
IMPULSE EJECTING ENEWD THROUGH THE GREAT LAKES AND SERN CANADA AHEAD
OF MAIN UPPER TROUGH WILL RESULT IN DEAMPLIFICATION OF UPPER RIDGE
OVER THE GREAT LAKES AND OH VALLEY. A COLD FRONT ACCOMPANYING THIS
FEATURE IS FORECAST TO INITIALLY EXTEND FROM THE UPPER GREAT LAKES
SWWD INTO THE SRN PLAINS...AND FROM NERN U.S. SWWD INTO THE OH
VALLEY BY THE END OF THE PERIOD. LOW-MID 60S F DEWPOINTS WILL ADVECT
THROUGH WARM SECTOR...BUT MODEST LAPSE RATES SHOULD LIMIT MLCAPE TO
GENERALLY AOB 1500 J/KG. STORMS ARE EXPECTED TO DEVELOP ALONG AND
AHEAD OF FRONT AS THE ATMOSPHERE DESTABILIZES. IT STILL APPEARS THAT
STRONGER VERTICAL SHEAR WILL REMAIN POST FRONTAL...WITH MODEST
UNIDIRECTIONAL DEEP LAYER WINDS SUPPORTIVE OF MULTICELLS. A FEW
STORMS COULD BECOME CAPABLE OF PRODUCING MAINLY ISOLATED STRONG WIND
GUSTS THROUGH EARLY EVENING. EXPECTED MODEST SHEAR/INSTABILITY
PARAMETER SPACE PRECLUDES INTRODUCING MORE THAN 5% SEVERE
PROBABILITIES AT THIS TIME.

...SERN STATES...
CUTOFF UPPER LOW IS FORECAST TO BECOME AN OPEN WAVE TROUGH AND SHIFT
EWD THROUGH THE SERN STATES. ATMOSPHERE WILL LIKELY ONCE AGAIN
BECOME MODERATELY UNSTABLE AS THE BOUNDARY LAYER WARMS. WEAK
VERTICAL SHEAR WILL SUPPORT MULTICELL AND PULSE STORMS...A FEW OF
WHICH COULD PRODUCE ISOLATED MARGINALLY SEVERE HAIL AND DOWNBURST
WINDS.

COLD FRONT TRAILING SWWD FROM SURFACE LOW NRN MN THRU WRN IA TO NWRN
OK AND ERN NM WILL BE THE FOCUS FOR THE RATHER LOW END SEVERE
CONCERN TODAY.

ANY SEVERE THREAT SHOULD DIMINISH QUICKLY WITH LOSS OF HEATING BY
THIS EVENING.
