CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 070317Z - 070515Z

ELEVATED CONVECTION IS FORECAST TO DEVELOP/INCREASE ACROSS CENTRAL
AND NERN KS AND THEN SPREAD/EXPAND ENEWD WITH TIME. WITH
MARGINALLY-SEVERE HAIL POSSIBLE WITH STRONGER CELLS...WW MAY BE
NEEDED.

EVENING TOP RAOB REVEALS A DEEP DRY LAYER THROUGH ROUGHLY 600 MB
ALONG WITH AN ABSENCE OF CAPE. HOWEVER...STRONG SLY FLOW AT LOW
LEVELS -- WHICH WILL INCREASE THROUGH THE EVENING -- WILL CONTINUE
TO PROVIDE NOT ONLY LOW-LEVEL ASCENT...BUT MOISTENING AROUND 850 MB.
AS A RESULT...ELEVATED CAPE SHOULD SLOWLY INCREASE -- WITH A
MODIFICATION OF THE 00Z TOPEKA RAOB TO REFLECT DOWNSTREAM /NORMAN
OK/ MOISTURE AROUND H8 RESULTING IN AROUND 900 J/KG MOST-UNSTABLE
CAPE.

ASSUMING THIS DEGREE OF DESTABILIZATION...MID-LEVEL FLOW 60 TO 70 KT
FROM THE WSW WILL CONTRIBUTE TO AMPLE SPEED SHEAR FOR ORGANIZED
STORMS. THUS -- WITH HAIL THREAT EXPECTED TO GRADUALLY INCREASE IN
CONJUNCTION WITH AN EXPANSION/INTENSIFICATION OF CONVECTION WITH
TIME...WW MAY BE REQUIRED.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0644 PM CST FRI MAR 06 2009

VALID 070100Z - 071200Z

...THERE IS A SLGT RISK OF SVR TSTMS TONIGHT ACROSS PARTS OF THE E
CNTRL PLAINS AND MIDDLE MISSISSIPPI VALLEY....

...IMMEDIATE LEE OF THE SOUTHERN ROCKIES...
WEAK THUNDERSTORM STORM ACTIVITY HAS BEEN ONGOING THE PAST FEW HOURS
NEAR THE SANGRE DE CRISTO MOUNTAINS...WHERE STEEPENING LAPSE RATES
WITH THE HEATING OF THE HIGHER TERRAIN HAS SUPPORTED WEAK
DESTABILIZATION. FAVORABLE OROGRAPHIC FORCING BENEATH DIVERGENT
UPPER FLOW DOWNSTREAM OF AN UPPER TROUGH ACROSS THE INTERMOUNTAIN
WEST HAS SUPPORTED CONVECTIVE DEVELOPMENT...BUT THIS HAS BEEN
MINIMIZED BY LIMITED MOISTURE AVAILABILITY. WHILE IT SEEMS MOST
PROBABLE THAT ACTIVITY WILL DIMINISH BY OR SHORTLY AFTER SUNSET...IT
IS POSSIBLE THAT LARGE-SCALE FORCING MAY BE SUFFICIENT TO MAINTAIN A
COUPLE OF STORMS FOR AN HOUR OR TWO AFTER NIGHTFALL.

...CENTRAL PLAINS THRU OHIO VALLEY...
EAST OF THE ROCKIES...SUBTROPICAL RIDGING REMAINS STRONG ACROSS MUCH
OF THE SOUTH CENTRAL AND SOUTHEASTERN STATES. COUPLED WITH
WARM...MIXED BOUNDARY LAYER AIR ADVECTING EAST NORTHEASTWARD OFF THE
PLATEAU REGION...THIS IS CAPPING A WEAK LOW-LEVEL MOISTURE RETURN
OFF THE WESTERN GULF OF MEXICO. AN EXCEPTION EXISTS ALONG A WEAK
SURFACE BOUNDARY ACROSS THE TEXAS PANHANDLE...WHICH HAS
STALLED...AND ALREADY APPEARS TO BE LIFTING NORTHWARD. LOW-LEVEL
WARM ADVECTION ALONG THE BOUNDARY MAY BE SUPPORTING DEVELOPMENT...
BUT HEATING TO CONVECTIVE TEMPERATURES IS PROBABLY THE MOST
PROMINENT FORCING...AND THESE STORMS MAY BE FAIRLY SHORT-LIVED.

THE PRIMARY FOCUS FOR CONVECTIVE DEVELOPMENT TONIGHT STILL APPEARS
TO BE A QUASI-STATIONARY LOWER/MID TROPOSPHERIC FRONT EXTENDING WEST
SOUTHWEST OF THE OHIO VALLEY...THROUGH THE CENTRAL PLAINS...NEAR THE
CREST OF THE SUBTROPICAL RIDGE. LOW-LEVEL MOISTURE RETURN TO THE
VICINITY OF THIS BOUNDARY...COINCIDENT WITH STEEPENING ISENTROPIC
ASCENT...AIDED BY AT LEAST WEAK FRONTOGENETIC FORCING...AND
STRENGTHENING DIVERGENT UPPER FLOW IN THE RIGHT ENTRANCE REGION OF
AN INTENSIFYING HIGH-LEVEL JET...IS EXPECTED TO SUPPORT WEAK TO
MODERATE DESTABILIZATION. THE STRONGEST DESTABILIZATION...WITH MOST
UNSTABLE CAPE GENERALLY ON THE ORDER OF 500-1000 J/KG SEEMS MOST
LIKELY ACROSS PARTS OF NORTH CENTRAL/NORTHEAST KANSAS THROUGH
NORTHERN MISSOURI...ACCOMPANIED BY INCREASING STORM COVERAGE AFTER
06Z. IT IS POSSIBLE THAT FORCING ON THE NOSE OF A NOCTURNALLY
STRENGTHENING LOW-LEVEL JET COULD SUPPORT THE INITIATION OF STORMS
AS EARLY AS THE 03-06Z TIME FRAME...A BIT FARTHER TO THE
WEST...ACROSS PARTS OF WESTERN/CENTRAL KANSAS.

STORMS ARE EXPECTED TO BE BASED ABOVE A NEAR SURFACE STABLE LAYER.
HOWEVER...GIVEN A FAVORABLE THERMODYNAMIC ENVIRONMENT ALOFT...
STRONG SHEAR WITHIN THE ELEVATED INFLOW LAYER...AND THROUGH THE
CONVECTIVE LAYER...WILL ENHANCE THE RISK FOR LARGE HAIL IN THE MOST
VIGOROUS STORMS. ALTHOUGH LOW-LEVEL TEMPERATURE/DEW POINT SPREADS
WILL BE INITIALLY LARGE...THE RISK FOR DAMAGING WIND GUSTS STILL
APPEARS LOW.

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 070004Z - 070130Z

ISOLATED/DIURNALLY-DRIVEN STORM DEVELOPMENT MAY CONTINUE THROUGH
EARLY EVENING NEAR THE CAPROCK REGION OF THE CENTRAL TX PANHANDLE.
STRONGEST CELLS COULD PRODUCE SMALL TO MARGINALLY-SEVERE HAIL OR A
LOCALLY-STRONG WIND GUST...BUT WW NOT ANTICIPATED ATTM.

LATEST RADAR SHOWS CONVECTIVE DEVELOPMENT OCCURRING ALONG THE
CAPROCK SE OF AMARILLO...WITH STORMS THEN SPREADING NEWD AND
WEAKENING AS THEY APPROACH THE OK/TX BORDER.

THE CONVECTION IS DEVELOPING IN AN ENVIRONMENT OF
MARGINAL/HIGH-BASED CAPE...ALONG THE WRN EDGE OF A MODEST RETURN OF
BOUNDARY-LAYER MOISTURE WHOSE WWD SPREAD IS BEING INHIBITED BY THE
HIGHER TERRAIN.

AREA VWP/PROFILER DATA SHOW A WIND FIELD VEERING/INCREASING WITH
HEIGHT TO 50 TO 60 KT AT MID LEVELS -- AND THUS SHEAR SUPPORTIVE OF
ORGANIZED STORMS. HOWEVER...WITH THE COMBINATION OF MARGINAL
INSTABILITY AND THE CONTINUED ISOLATED NATURE OF CELL DEVELOPMENT
CURRENTLY EXPECTED...ANY SEVERE THREAT SHOULD REMAIN QUITE MARGINAL
AND VERY ISOLATED...AND THUS WW WILL LIKELY NOT BE NEEDED.

DAY2SVR: Nws Storm Prediction Center Norman Ok

SWODY2
SPC AC 061709

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1109 AM CST FRI MAR 06 2009

VALID 071200Z - 081200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF THE CNTRL/SRN
PLAINS INTO PORTIONS OF THE LOWER MO AND OH VALLEYS...

...SYNOPSIS...

PRIMARY FEATURE OF INTEREST DURING THE DAY TWO PERIOD WILL BE
MIDLEVEL TROUGH WHICH WILL TRANSLATE NEWD FROM THE VICINITY OF THE
FOUR CORNERS REGION INTO THE CNTRL PLAINS. AN 80-100 KT MIDLEVEL
JET STREAK WILL ACCOMPANY THIS SYSTEM NEWD WITH THE MOST SIGNIFICANT
HEIGHT FALLS/DYNAMIC FORCING FOR ASCENT SHIFTING FROM THE SRN
ROCKIES INTO THE CNTRL PLAINS.

IN THE LOW LEVELS...LEE SURFACE CYCLONE ATTENDANT TO THIS SYSTEM
WILL DEEPEN SATURDAY OVER WRN KS BEFORE DEVELOPING NEWD INTO NRN MO
SATURDAY NIGHT. THIS LOW WILL DEVELOP ALONG A BAROCLINIC ZONE WHICH
WILL REMAIN LARGELY QUASI-STATIONARY THROUGH CNTRL KS...NRN MO INTO
THE OH VALLEY. A DRYLINE EXTENDING FROM THE LOW OVER SWRN KS INTO
WRN TX WILL EVENTUALLY BE OVERTAKEN SATURDAY NIGHT BY A PACIFIC
FRONT PUSHING EWD FROM THE CNTRL AND SRN HIGH PLAINS.

...CNTRL/SRN PLAINS INTO THE LOWER MO AND OH VALLEYS...

CLUSTERS OF ELEVATED TSTMS /SOME SEVERE/ ARE EXPECTED TO BE ONGOING
SATURDAY MORNING NEAR OR N OF QUASI-STATIONARY BOUNDARY OVER THE
LOWER MO INTO OH VALLEYS...DRIVEN LARGELY BY LOW-LEVEL CONVERGENCE
AND WAA ALONG NOSE OF SWLY...NOCTURNAL LLJ. A CONTINUED VEERING AND
EWD MIGRATION OF LLJ ACROSS THE OH VALLEY SHOULD MAINTAIN SIMILAR
REGIME OVER PORTIONS OF IL/IND THROUGH THE MORNING HOURS WITH THE
POTENTIAL FOR SOME HAIL WITH THE MORE INTENSE STORMS.

DYNAMIC RESPONSE TO APPROACHING MIDLEVEL TROUGH WILL RE-ESTABLISH A
SLY LLJ OVER THE CNTRL/SRN PLAINS SATURDAY...WHICH WILL SERVE TO
ENHANCE THE NWD FLUX OF AN INCREASINGLY MOIST AIR MASS WITH
DEWPOINTS RISING THROUGH THE 50S. THIS MOISTURE COUPLED WITH
DIURNAL HEATING AND RATHER STEEP MIDLEVEL LAPSE RATES OF 7-8 C/KM
WILL RESULT IN A MODERATELY UNSTABLE AIR MASS BY AFTERNOON OVER THE
KS/OK WARM SECTOR WITH MLCAPE APPROACHING 1000 J/KG. HOWEVER...
LATEST MODEL GUIDANCE SUGGESTS THAT INITIAL...SURFACE-BASED STORM
DEVELOPMENT MAY BE DELAYED BY: 1) RESIDUAL CAP ASSOCIATED WITH
EML...AND 2) POTENTIALLY LIMITED BOUNDARY LAYER HEATING DUE TO
THICKER MID AND HIGH CLOUDINESS.

CURRENTLY...IT APPEARS THAT THE HIGHEST PROBABILITY OF STORM
INITIATION WILL BE NEAR OR AFTER 08/00Z ALONG THE I-35/135 CORRIDOR
IN KS AS STRONGER HEIGHT FALLS ASSOCIATED WITH UPPER TROUGH BEGINS
TO ERODE CAP. THIS AREA WILL BE LOCATED TO THE E/NE OF SURFACE
CYCLONE WHERE COMBINATION OF BACKED LOW-LEVEL FLOW AND STRENGTHENING
MID/HIGH-LEVEL WIND FIELDS WILL RESULT IN VERTICAL SHEAR QUITE
SUPPORTIVE OF SUPERCELLS. WHILE LARGE HAIL WILL BE THE PRIMARY
SEVERE WEATHER THREAT...A TORNADO OR TWO WILL BE POSSIBLE WITH ANY
MORE INTENSE/LONG-LIVED STORMS THAT CAN BECOME ESTABLISHED.

STORMS SHOULD GROW UPSCALE INTO CLUSTERS OR A QLCS WITH A SEVERE
HAIL/DAMAGING WIND THREAT DEVELOPING EWD/NEWD ACROSS ERN KS INTO
WRN/NRN MO SATURDAY NIGHT. GIVEN THE PRESENCE OF THE CAP AND
DECREASING LARGE-SCALE FORCING WITH SWD EXTENT...THERE IS SOME
QUESTION AS TO HOW FAR S STORMS WILL DEVELOP ALONG SURGING PACIFIC
FRONT. ATTM...IT DOES APPEAR THAT ISOLATED SEVERE STORMS WILL BE
POSSIBLE AT LEAST INTO PARTS OF N-CNTRL INTO NERN OK DURING THE
LATTER HALF OF THE FORECAST PERIOD.

VALID 061630Z - 071200Z

...THERE IS A SLGT RISK OF SVR TSTMS TONIGHT AND EARLY SAT FROM
PARTS OF THE E-CNTRL PLAINS ACROSS THE LOWER MO RIVER VALLEY...

...SYNOPSIS...
MORNING WV IMAGERY INDICATES FAST MOVING SHORTWAVE TROUGH EJECTING
RAPIDLY NEWD ACROSS THE CENTRAL ROCKIES...WHICH WILL CONTINUE TO
LOSE AMPLITUDE AS IT LIFTS ACROSS THE CENTRAL PLAINS. THIS WILL
OCCUR WITHIN LARGE POSITIVELY-TILED TROUGH REMAINING IN PLACE FROM
THE NRN PLAINS INTO THE INTERMOUNTAIN WEST...WITH PRIMARY ENERGY
DIGGING ACROSS THE GREAT BASIN OVERNIGHT.

MORNING UPPER AIR ANALYSES INDICATE DRY/STABLE AIR WILL PERSIST
ACROSS THE NATION FOR MUCH OF THE DAY. HOWEVER...UPWARD-MIXING OF
GREATER NEAR SURFACE MOISTURE IS EXPECTED ACROSS THE SRN PLAINS THIS
AFTERNOON AS STRONG HEATING PRODUCES DEEPLY MIXED BOUNDARY LAYER
THROUGH H85. THIS IN TURN WILL ADVECT NWD THROUGH THE
EVENING/OVERNIGHT ATOP STABILIZING BOUNDARY LAYER TO THE SOUTH OF A
SURFACE FRONT EXPECTED TO STALL E-W FROM NRN MO ACROSS NRN KS TO LOW
OVER E-CENTRAL CO DURING THE EVENING. SLY LLJ AND ATTENDANT GREATER
THETA-E ADVECTION/LIFT WILL INCREASE INTO PORTIONS OF KS/SRN NEB/NRN
MO/SRN IA IN RESPONSE TO STRONG IMPULSE DIGGING INTO THE CENTRAL
ROCKIES BY THE END OF THE PERIOD. FORECAST SOUNDINGS INDICATE
MOISTENING AT THE BASE OF PRONOUNCED ELEVATED MIXED LAYER/STEEP MID
LEVEL LAPSE RATES WILL BECOME SUFFICIENT FOR MODERATE MUCAPE AND
LITTLE OR NO INHIBITION BETWEEN 03-06Z. THIS WILL RESULT IN
ELEVATED THUNDERSTORM DEVELOPMENT WITH SUFFICIENT SHEAR WITHIN THE
CLOUD-LAYER FOR ROTATING STORMS WITH THE MORE VIGOROUS UPDRAFTS.
ACTIVITY IS EXPECTED TO EXPAND OVERNIGHT AS IT SHIFTS STEADILY ENEWD
ACROSS THE LOWER MO RIVER VALLEY. HAIL...SOME OF WHICH IS EXPECTED
TO EXCEED SEVERE CRITERIA...IS EXPECTED WITH THE MORE ROBUST STORMS.

VALID 061300Z - 071200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE LWR MO INTO THE MID MS
VLYS...

...SYNOPSIS...
PATTERN WILL EVOLVE TOWARD A SPLIT FLOW OVER THE WRN HALF OF THE
NATION THROUGH SAT AS /1/ A MAJOR PORTION OF POSITIVE TILT TROUGH
NOW OVER WRN NOAM HEADS E ACROSS SRN SK/MB...AND /2/ SPEED MAX NOW
OVER WA/ORE CONTINUES SSE TO CARVE AN UPR LOW OVER THE GRT BASIN.
AT THE SAME TIME...HEIGHTS SHOULD REBOUND SLIGHTLY FROM THE MID MS
VLY TO THE MID ATLANTIC CST IN WAKE OF IMPULSE NOW CROSSING THE UPR
GRT LKS.

AT THE SFC...WRN PART OF FRONT NOW BECOMING STNRY FROM OK TO IL/MI
SHOULD RETURN N ACROSS PARTS OF KS/MO LATER TODAY/TONIGHT AS CO
CYCLOGENESIS OCCURS IN RESPONSE TO AMPLIFYING GRT BASIN TROUGH.

...LWR MO TO MID MS VLYS...
AFOREMENTIONED FRONT SHOULD STRENGTHEN OVER THE CNTRL STATES THROUGH
THE PERIOD AS DEVELOPING CONFLUENT ZONE ALOFT MAINTAINS SFC RIDGE
OVER THE DAKOTAS...AND SSWLY RETURN FLOW/LLJ INCREASE OVER THE SRN
PLNS. THE BOUNDARY LIKELY WILL SERVE AS A FOCUS FOR TSTMS
TONIGHT/SAT AS INCREASING UPR DIVERGENCE AND DEVELOPMENT OF JET
ENTRANCE REGION ALOFT /IN ASSOCIATION WITH GRT BASIN LOW/ ENHANCE
DEEP ASCENT ALONG IT.

SATELLITE PW AND SFC/850 MB DATA SUGGEST THAT MOISTURE AVAILABILITY
TO THE LWR MO/MID MS VLY WILL REMAIN RATHER MODEST THROUGH THE
PERIOD...WITH PW VALUES RISING TO AROUND 1 INCH BY THE END OF THE
PERIOD. NEVERTHELESS...MID LVL LAPSE RATES WILL BE STEEP. IN
ADDITION...AMPLE /40-50 KT/...LARGELY UNIDIRECTIONAL CLOUD LAYER
SHEAR WILL BE PRESENT TO FOSTER HAIL DEVELOPMENT.

COMBINATION OF EML CAPPING AND ABSENCE OF DEEP FORCING FOR ASCENT
SHOULD PRECLUDE STORM DEVELOPMENT INVOF FRONT THROUGH THIS EVE.
STRENGTHENING LOW TO MID LVL FORCING SHOULD...HOWEVER...SUPPORT
STORM DEVELOPMENT AFTER 07/06Z. THESE MAY FIRST FORM OVER PARTS OF
NET KS/SE NEB...ON NOSE OF STRENGTHENING SSWLY LLJ...BEFORE
MOVING/DEVELOPING E ALONG FRONT THROUGH 12Z SAT. ONE OR MORE
LOOSELY ORGANIZED CLUSTERS OF STORMS MAY FORM...WITH MOST OF THE
ACTIVITY LIKELY TO BE SLIGHTLY ELEVATED ON N SIDE OF FRONT. DESPITE
ELEVATED NATURE...COMBINATION OF 500-1000 J/KG MUCAPE AND STRONG
CLOUD LAYER SHEAR COULD YIELD A FEW SUSTAINED/POSSIBLY ROTATING
UPDRAFTS WITH SVR HAIL.

0358 AM CST FRI MAR 06 2009

VALID 091200Z - 141200Z

...DISCUSSION...
00Z GEFS/ECMWF GENERALLY AGREE WITH THE EXPECTED EASTWARD EVOLUTION
OF A BROAD UPPER TROUGH FROM THE NORTHERN INTERMOUNTAIN WEST TO THE
GREAT LAKES REGION DURING THE EARLY/MIDDLE PART OF NEXT WEEK. THE
INITIAL CONCERN FOR THE POSSIBILITY OF SEVERE TSTMS WILL BE ON DAY
4/MONDAY...PRIMARILY ACROSS PORTIONS OF THE SOUTH CENTRAL PLAINS AND
LOWER MO VALLEY. IT SEEMS LIKELY THAT THE WEEKEND FRONTAL BOUNDARY
WILL HAVE STALLED ACROSS THE MID-SOUTH AND NORTH TX/SOUTH OK
VICINITY...WITH THIS FRONTAL BOUNDARY EXPECTED TO RETREAT NORTHWARD
ACROSS OK/KS/MO ON MONDAY/DAY 4...ACCOMPANIED BY AROUND 60F
DEWPOINTS. WITH EXPECTATIONS FOR SUFFICIENT
MOISTURE/INSTABILITY...THE APPROACHING UPPER TROUGH/LARGE SCALE
HEIGHT FALLS AND AMPLE VERTICAL SHEAR WOULD SUPPORT A RISK FOR
SEVERE TSTMS MONDAY AFTERNOON/NIGHT.

FOR DAY 5/TUESDAY...WITH THE UPPER TROUGH LIKELY TO OVERSPREAD THE
NORTHERN PLAINS/UPPER MIDWEST...A RISK OF SEVERE TSTMS COULD
CONTINUE INTO THE MIDWEST/OHIO VALLEY ALONG/AHEAD OF A QUICKLY
ADVANCING SURFACE LOW/COLD FRONT. WHILE AT LEAST SOME SEVERE THREAT
SEEMS LIKELY IN THIS SCENARIO...INHERENT MODEL VARIABILITY/FORECAST
UNCERTAINTY PRECLUDES A 30% DAY-1 EQUIVALENT SEVERE RISK AT THIS
TIME.

THEREAFTER...WITH THE CENTRAL STATES PORTION OF THE COLD FRONT
LIKELY TO BE SHUNTED SOUTHWARD...FOCUS FOR ANY MID WEEK SEVERE
POTENTIAL WILL SHIFT SOUTHWARD ACCORDINGLY TO PERHAPS PORTIONS OF
TX/LOWER MS RIVER VALLEY. HOWEVER...SUFFICIENTLY LOW
PREDICTABILITY/POTENTIAL PRECLUDES ANY SEVERE RISK AREAS.

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE MIDWEST/LOWER OH

...MIDWEST/OHIO VALLEY/MID-SOUTH...
VARIABILITY EXISTS AMONGST 00Z SUITE OF NUMERICAL MODELS...BUT
GENERAL CONSENSUS SUGGESTS A RELATIVELY COMPACT/NEGATIVELY TILTED
SHORTWAVE TROUGH WILL ADVANCE NORTHEASTWARD ACROSS THE UPPER MIDWEST
ON SUNDAY. ONGOING EARLY DAY TSTMS COULD POSE A SEVERE HAIL THREAT
ACROSS PORTIONS OF IA/MO/IL AND PERHAPS INDIANA. WITH COLD PROFILES
ALOFT/STEEP MID LEVEL LAPSE RATES ATTENDANT TO THE UPPER
TROUGH...GRADUAL DIURNAL DESTABILIZATION/NEAR-SURFACE SOUTHWESTERLY
MOISTURE INFLUX OF NEAR 60F DEWPOINTS AND UNSEASONABLY WARM
TEMPERATURES SHOULD LEAD TO AN UPSWING IN TSTM INTENSITY BY LATE
MORNING/EARLY AFTERNOON AHEAD OF THE ADVANCING SURFACE LOW/COLD
FRONT. SEVERE HAIL AND DAMAGING WINDS SHOULD BE THE PRIMARY
RISKS...ALTHOUGH AN ISOLATED TORNADO CANNOT BE RULED OUT.

...ARKLATEX VICINITY...
THE SEVERE THREAT APPEARS MUCH MORE CONDITIONAL WITH SOUTHWESTWARD
EXTENT ACROSS THE ARKLATEX VICINITY ON SUNDAY. ALTHOUGH STRONG WIND
FIELDS ALOFT WILL REMAIN JUXTAPOSED ATOP UPPER 50S TO AROUND 60F
SURFACE DEWPOINTS...WEAKENING FRONTAL CONVERGENCE ALONG THE STALLING
COLD FRONT...AND WEAK/AMORPHOUS LARGE SCALE FORCING IN THE WAKE OF
THE MIDWEST UPPER TROUGH...LEAD TO CONSIDERABLE UNCERTAINTY
REGARDING THE POTENTIAL EXTENT/MAGNITUDE OF ANY SEVERE THREAT. AN
APPRECIABLY ORGANIZED SEVERE RISK IS NOT EXPECTED AT THIS TIME
ACROSS THE ARKLATEX REGION...BUT WILL MAINTAIN 5% SEVERE
PROBABILITIES WITH A REEVALUATION IN SUBSEQUENT OUTLOOKS.

VALID 071200Z - 081200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE SOUTH CENTRAL PLAINS
AND LOWER/MIDDLE MO VALLEY...

...SYNOPSIS...
AN INITIALLY NEUTRAL TILT UPPER TROUGH IS EXPECTED TO STEADILY
TRANSITION EAST-NORTHEASTWARD FROM THE EASTERN GREAT BASIN/FOUR
CORNERS REGION EARLY SATURDAY...TO THE CENTRAL PLAINS/MIDDLE MO
VALLEY BY EARLY SUNDAY WHERE IT IS EXPECTED TO TAKE ON MORE OF A
NEGATIVE TILT. AT THE SURFACE...FRONTAL BOUNDARY IS EXPECTED TO
STALL/BECOME ESTABLISHED IN A GENERAL WEST-EAST CORRIDOR FROM KS TO
THE MIDWEST/OHIO VALLEY. LEE-SIDE SURFACE CYCLOGENESIS WILL OCCUR
DURING THE DAY ACROSS THE HIGH PLAINS...WITH A GRADUALLY DEEPENING
SURFACE LOW AND SHARPENING COLD FRONT/DRYLINE EXPECTED TO DEVELOP
EASTWARD ACROSS PORTIONS OF KS/OK/TX SATURDAY AFTERNOON/NIGHT. IN
THE PREFRONTAL WARM SECTOR...BOUNDARY LAYER MOISTURE WILL REMAIN
MODEST...WITH RETURN LIMITED IN THE WAKE OF LAST WEEKENDS DEEP
FRONTAL PENETRATION INTO THE GULF OF MEXICO.

...MIDDLE MO VALLEY TO IL/INDIANA SATURDAY MORNING...
SIMILAR TO THE LATE DAY 1 SCENARIO...SCATTERED ELEVATED
STRONG/POTENTIALLY SEVERE TSTMS WILL BE ONGOING AT THE BEGINNING OF
THE PERIOD SATURDAY MORNING VIA A 50 KT LOW LEVEL JET AIDED WARM
ADVECTION/ELEVATED MOISTURE TRANSPORT REGIME. AMIDST AMPLE SHEAR
THROUGH THE CLOUD BEARING LAYER FOR UPDRAFT ROTATION...A STEEP LAPSE
RATE ENVIRONMENT AND ELEVATED MUCAPE TO 500-1000 J/KG WILL SUPPORT A
CONTINUED HAIL RISK DURING THE MORNING ACROSS NORTHERN MO/SOUTHERN
IA INTO IL/INDIANA. THESE TSTMS AND ANY ASSOCIATED HAIL THREAT
SHOULD GRADUALLY SHIFT EAST-NORTHEASTWARD DURING THE MORNING ALONG
THE SURFACE-850 MB BAROCLINIC ZONE...WITH THE HAIL THREAT EXPECTED
TO WANE THROUGH MID/LATE MORNING AS THE LOW LEVEL JET WEAKENS/VEERS
WESTERLY.

...KS/OK/MO SATURDAY AFTERNOON/EVENING...
AHEAD OF THE UPPER TROUGH CROSSING THE ROCKIES...KS/OK SHOULD REMAIN
CAPPED MUCH OF THE DAY. HOWEVER...SUFFICIENT HEATING AND ONSET OF
LARGE SCALE HEIGHT FALLS COULD BE SUFFICIENT FOR ISOLATED SURFACE
BASED TSTM DEVELOPMENT AS EARLY AS MID AFTERNOON...BUT IT MUCH MORE
LIKELY SATURDAY EVENING ACROSS CENTRAL/EASTERN KS INTO OK
ALONG/AHEAD OF THE ADVANCING SURFACE LOW AND COLD FRONT/DRYLINE.
WARM SECTOR SURFACE DEWPOINTS WILL LIKELY TO BE LIMITED TO THE
LOWER/MIDDLE 50S F ACROSS THE SOUTH CENTRAL PLAINS/MO VALLEY
SATURDAY AFTERNOON/EVENING...AND THIS WILL BE THE PRIMARY LIMITING
FACTOR FOR A MORE APPRECIABLE SEVERE RISK. REGARDLESS...INCREASINGLY
STEEP MID LEVEL LAPSE RATES ATOP MODEST BOUNDARY LAYER MOISTURE
SHOULD RESULT IN 500-800 J/KG OF MLCAPE BY LATE AFTERNOON. BENEATH
50+ KT OF SOUTHWESTERLY MID LEVEL FLOW...STRONG SHEAR/AMPLE VEERING
WOULD SUPPORT A RISK OF WELL-ORGANIZED TSTMS INCLUDING
SUPERCELLS...WITH THE PRIMARY RISK OF SEVERE HAIL. IN SPITE OF A
RATHER DYNAMIC SCENARIO WITH STRONG SHEAR...THE LIMITED MOISTURE
SHOULD FAVOR A QUICKLY DECOUPLING BOUNDARY LAYER WITHIN AN HOUR OR
TWO OF SUNSET...WITH A NOCTURNAL TENDENCY FOR TSTMS TO BE BASED
ABOVE A SHALLOW STABLE LAYER.

...SOUTHERN OK/NORTH TX SATURDAY AFTERNOON/EVENING...
AS THE SOUTHERN PERIPHERY OF THE APPROACHING UPPER TROUGH/LARGE
SCALE HEIGHT FALLS...TSTM POTENTIAL/COVERAGE AND ANY ASSOCIATED
SEVERE THREAT BECOMES MUCH MORE CONDITIONAL WITH SOUTHWARD EXTENT
ACROSS SOUTHERN OK INTO PORTIONS OF NORTH CENTRAL TX. IF/WHERE TSTMS
DEVELOP SATURDAY LATE AFTERNOON/EARLY EVENING...MODEST INSTABILITY
AND FAVORABLE SHEAR PROFILES WOULD CONDITIONALLY SUPPORT A RISK OF
SUPERCELLS WITH MAINLY A SEVERE HAIL RISK.

...NORTHEAST KS/SOUTHEAST NEB TO IA/NORTHERN MO/IL LATE...
AS THE UPPER TROUGH REACHES THE CENTRAL PLAINS...AN INTENSIFYING LOW
LEVEL JET /50-55 KT/ AND ASSOCIATED WARM ADVECTION REGIME SHOULD
AGAIN INCREASE HAIL POTENTIAL ACROSS THE MIDDLE MO VALLEY/MIDWEST
SATURDAY NIGHT INTO EARLY SUNDAY.

MODELS INDICATE THAT A VIGOROUS SHORT WAVE TROUGH...NOW PROGRESSING
THROUGH THE CREST OF A SHARP EASTERN PACIFIC UPPER RIDGE...WILL DIG
TO LEE OF THE RIDGE AXIS...ACROSS THE NORTHEAST PACIFIC...INTO THE
CANADIAN ROCKIES BY 12Z SATURDAY. AS THIS OCCURS...A SPLIT IN THE
DOWNSTREAM UPPER FLOW REGIME IS PROGGED TO BECOME MORE
PRONOUNCED...WITH A SIGNIFICANT NORTHERN STREAM SHORT WAVE TROUGH
TURNING EASTWARD ACROSS THE CENTRAL CANADIAN PROVINCES...WHILE AN
INCREASINGLY DETACHED SOUTHERN STREAM IMPULSE DIGS ACROSS THE
NORTHERN INTERMOUNTAIN REGION INTO THE GREAT BASIN. SUBTROPICAL
RIDGING IS FORECAST TO REMAIN STRONG ACROSS THE SOUTH CENTRAL AND
SOUTHEASTERN STATES...AND RIDGING MAY BUILD AHEAD OF THE SLOWER
SOUTHERN STREAM IMPULSE...ACROSS THE CENTRAL PLAINS AND MIDDLE
MISSISSIPPI VALLEY. MODELS SUGGEST THAT THIS WILL OCCUR AS THE BASE
OF THE NORTHERN STREAM SHORT WAVE TROUGH PROGRESSES ALONG THE
CENTRAL INTERNATIONAL BORDER AREA...TOWARD THE UPPER GREAT
LAKES...CONTRIBUTING TO AN INTENSIFYING HIGH LEVEL JET IN AN ARC
FROM THE MID MISSOURI VALLEY THROUGH THE GREAT LAKES AND NORTHEAST.

...EAST CENTRAL PLAINS INTO THE OHIO VALLEY...
IN RESPONSE TO THE EVOLVING UPPER FLOW PATTERN...A SIGNIFICANT
LOWER/MID TROPOSPHERIC BAROCLINIC ZONE IS EXPECTED TO BECOME
QUASI-STATIONARY ACROSS PARTS OF NORTHEAST KANSAS/SOUTHEAST NEBRASKA
THROUGH THE IOWA/MISSOURI BORDER AREA INTO THE OHIO VALLEY. AN
ASSOCIATED SURFACE FRONT MAY ADVANCE SOUTH OF THIS POSITION AND
LINGER THROUGH MUCH OF THE DAY...AS A RETURN FLOW OF MOISTURE
CONTINUES OFF THE GULF OF MEXICO INTO THE CENTRAL PLAINS/OZARK
PLATEAU. CHARACTERIZED BY SURFACE DEW POINTS IN THE MID/UPPER
50S...THIS MOISTURE RETURN DOES NOT APPEAR PARTICULARLY
SUBSTANTIAL...ESPECIALLY GIVEN THE WARMTH OF THE LOWER/MID
TROPOSPHERIC AIR MASS ADVECTING INTO THE REGION FROM THE PLATEAU
REGION. AND...THIS CAPPING IS EXPECTED TO SUPPRESS CONVECTIVE
DEVELOPMENT THROUGH THE DAY...AND PERHAPS WELL INTO THE EVENING
HOURS.

HOWEVER...STRENGTHENING LOWER/MID-LEVEL FRONTOGENETIC FORCING IS
PROGGED ALONG THE MAIN BAROCLINIC BAND LATE THIS EVENING AND
OVERNIGHT. THIS PROBABLY WILL BECOME SUFFICIENT TO SUPPORT
INCREASING CONVECTIVE DEVELOPMENT AFTER 07/06Z. STORMS MAY INITIATE
FIRST ACROSS PARTS OF NORTHEAST KANSAS/SOUTHEAST NEBRASKA ...ON THE
NOSE OF A NOCTURNALLY STRENGTHENING LOW-LEVEL JET ASSOCIATED WITH AN
EVOLVING CENTRAL PLAINS CYCLONE...BEFORE SPREADING/DEVELOPING
EASTWARD ALONG THE FRONTAL ZONE THROUGH THE REMAINDER OF THE PERIOD.
ONE OR MORE CLUSTERS OF STORMS MAY EVENTUALLY FORM...AIDED BY
DIVERGENT UPPER FLOW IN THE RIGHT ENTRANCE REGION OF THE
STRENGTHENING HIGH LEVEL JET STREAK.

FORECAST SOUNDINGS INDICATE THAT ACTIVITY WILL BE BASED ABOVE A
RESIDUAL COOL/STABLE NEAR SURFACE LAYER. BUT...STEEP MID-LEVEL
LAPSE RATES MAY CONTRIBUTE TO CAPE OF 500-1000 J/KG...AND A
FAVORABLE ENVIRONMENT FOR THE PRODUCTION OF LARGE HAIL. THIS WILL
BE ENHANCED BY STRONG SHEAR WITHIN THE ELEVATED INFLOW LAYER...AND
THROUGH THE CONVECTIVE LAYER...SUPPORTIVE OF SIGNIFICANT UPDRAFT
ROTATION.
