CONCERNING...SEVERE THUNDERSTORM WATCH 153...

VALID 120734Z - 120830Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 153
CONTINUES.

EARLY MORNING SURFACE ANALYSIS SHOWED AN AREA OF LOW PRESSURE ALONG
THE NERN NM/SERN CO BORDER...WITH A WARM FRONT EXTENDING EWD THROUGH
FAR SRN KS...THEN ENEWD INTO SWRN MO /25 N SGF/ TO EAST CENTRAL MO
/20 N FAM/...AND THROUGH THE SRN QUARTER OF IL TO SRN IND. WSR-88D
VADS AND WIND PROFILERS OVER THE SRN PLAINS INDICATED A BROAD...
STRONG LLJ /50-65 KT/ EXTENDING INTO KS AND MO. THUS...STRONG LOW
LEVEL WAA WILL BE MAINTAINED INTO THESE TWO STATES THROUGH DAYBREAK.

...KS/CENTRAL-ERN NEB...
REGIONAL RADAR IMAGERY SHOWED THE STRONGEST STORM WAS TRACKING ENEWD
THROUGH THE WRN HALF OF WW 153. AT 725Z...THIS STORM WAS LOCATED 55
NNW P28. ADDITIONAL STORMS HAD ALSO DEVELOPED RECENTLY OVER
PORTIONS OF NORTH CENTRAL KS INTO CENTRAL NEB. THIS LATTER ACTIVITY
APPEARED TO BE LOCATED WITHIN A WAA REGIME IN THE VICINITY OF AN 850
MB FRONT WHICH EXTENDED FROM SWRN KS INTO SERN NEB TO SRN IA.

EFFECTIVE BULK SHEAR /EXCEEDING 50 KT/ WITH VECTORS ORIENTED
PARALLEL TO THE WARM FRONT WILL CONTINUE TO SUPPORT SUPERCELL
STRUCTURES WITHIN WW 153 WHERE ACTIVITY SHOULD REMAIN CLOSER TO A
MOIST AND MORE STRONGLY UNSTABLE INFLOW REGIME. FARTHER N...65 KT
SWLY MIDLEVEL WINDS OVER THE CENTRAL HIGH PLAINS...WEAK HEIGHT FALLS
EXPECTED THROUGH 12Z OVER NEB/NRN KS AND NRN EXTENT OF THE WAA
REGIME INTO NEB WILL SUPPORT ADDITIONAL STORMS SPREADING NEWD
THROUGH THIS MORNING. HOWEVER...THIS NRN ACTIVITY WILL REMAIN
FARTHER AWAY FROM A STRONGER INFLOW OF GREATER INSTABILITY...THUS
TENDING TO LIMIT THE OVERALL SEVERE THREAT.

...ERN KS/CENTRAL MO TO WRN IL...
TSTMS CONTINUE TO DEVELOP OVER SERN-EAST CENTRAL KS ALONG THE SWRN
FLANK OF A LARGE MCS WITH ONGOING ACTIVITY EXTENDING ENEWD THROUGH
MUCH OF CENTRAL MO /NORTH OF THE WARM FRONT/. FORCING FOR ASCENT
ATTENDANT TO A SHORTWAVE TROUGH/SPEED MAX CURRENTLY TRACKING NEWD
INTO SRN MO PER WATER VAPOR IMAGERY SHOULD CONTINUE TO SUPPORT THIS
MCS AS IT MOVES THROUGH MO TOWARD WRN IL. EMBEDDED LINE SEGMENTS
WITHIN ERN KS/MO MCS WILL REMAIN POSSIBLE OVERNIGHT GIVEN THE STRONG
SHEAR VECTORS ORIENTED PARALLEL TO THE WARM FRONT. ALTHOUGH LOCALLY
STRONG WIND GUSTS AND SMALL HAIL WILL BE POSSIBLE E AND NE OF WW
153...IT APPEARS THAT HEAVY RAINFALL RATES WILL BE THE PRIMARY
THREAT ACROSS MO...AND EVENTUALLY REACHING WRN IL. PW VALUES WILL
INCREASE AT AND ABOVE 1.5 INCHES SUPPORTING HEAVY RAINFALL RATES AS
STORMS TRAIN ENEWD.

SWODY3
SPC AC 120730

DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0230 AM CDT WED MAY 12 2010

VALID 141200Z - 151200Z

...SYNOPSIS...
MODELS SUGGEST THAT THE SUBTROPICAL RIDGE OVER THE EASTERN GULF OF
MEXICO/SOUTHEASTERN U.S. AND ADJACENT COASTAL WATERS WILL WEAKEN
SOME WHILE SHIFTING SLOWLY EASTWARD DURING THIS FORECAST PERIOD.
THIS IS EXPECTED TO OCCUR AS REMNANTS OF AN UPPER LOW/TROUGH
ACCELERATE EAST SOUTHEASTWARD THROUGH A CONFLUENT REGIME ACROSS THE
LOWER GREAT LAKES INTO THE NORTH ATLANTIC SEABOARD. MEANWHILE...A
SIGNIFICANT PORTION OF REMNANT TROUGHING ACROSS THE SOUTHWEST MAY
BEGIN TO SHIFT EASTWARD TOWARD THE SOUTHERN ROCKIES.

THE LATTER FEATURE APPEARS LIKELY TO CONTRIBUTE TO AT LEAST BROADLY
DIVERGENT UPPER FLOW ACROSS THE SOUTHERN PLAINS...WHERE A WEAK TO
MODEST SOUTHERLY LOW-LEVEL FLOW WILL PERSIST OFF THE WESTERN GULF OF
MEXICO. MODELS ARE SUGGESTIVE THAT RICHER GULF MOISTURE RETURN WILL
BECOME CUT-OFF ACROSS AREAS TO THE NORTH AND EAST...BUT RESIDUAL
LOW-LEVEL MOISTURE ALONG AND AHEAD OF A COLD FRONT ADVANCING
SOUTHWARD...TO THE SOUTH AND EAST OF THE OZARK PLATEAU AND OHIO
VALLEY...IS EXPECTED TO BE SUFFICIENT FOR CONSIDERABLE CONVECTIVE
DEVELOPMENT FRIDAY.

A BELT OF STRONGER FLOW ROUNDING THE CREST OF THE FLATTENING UPPER
RIDGE COULD PROVIDE POTENTIAL FOR ENHANCEMENT OF THUNDERSTORM
ACTIVITY ACROSS PARTS OF THE CUMBERLAND PLATEAU AND CENTRAL
APPALACHIANS INTO THE MID ATLANTIC COAST. HOWEVER...STABILIZING
LAPSE RATES AND WEAKER CAPE IN ITS VICINITY COMPARED TO PRIOR DAYS
ARE CONTRIBUTING TO MORE UNCERTAINTY CONCERNING SEVERE WEATHER
POTENTIAL.

MODERATING INSTABILITY AND SHEAR ACROSS THE SOUTHERN PLAINS WILL
PROBABLY ALSO LIMIT CONVECTIVE POTENTIAL. NEVERTHELESS...THE RISK
FOR SEVERE STORMS MAY NOT BE COMPLETELY NEGLIGIBLE...AS LARGE- SCALE
FORCING REMAINS FAVORABLE FOR FAIRLY WIDESPREAD THUNDERSTORM
ACTIVITY.

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN AND
CNTRL PLAINS...MID-MS VALLEY AND OH VALLEY...

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE
MID-ATLANTIC...

...SRN AND CNTRL PLAINS/MID-MO VALLEY
AN UPPER-LEVEL LOW IN THE CNTRL ROCKIES TODAY WILL ACCELERATE NEWD
AS A MID-LEVEL JET EJECTS NEWD ACROSS THE CNTRL AND SRN PLAINS. AT
THE SFC...A COLD FRONT WILL MOVE SSEWD ACROSS THE CNTRL PLAINS WITH
A MOIST AND VERY UNSTABLE AIRMASS IN PLACE ACROSS THE SLIGHT RISK
AREA. FORECAST SOUNDINGS JUST AHEAD OF THE FRONT AT 21Z FROM THE
MID-MO VALLEY TO THE SRN PLAINS SHOW MLCAPE VALUES IN THE 3000 TO
4000 J/KG RANGE. FORECAST SOUNDINGS DURING THE DAY SUGGEST THE WARM
SECTOR WILL REMAIN CAPPED UNTIL LATE AFTERNOON WHEN THE MODELS
INTIATE NUMEROUS THUNDERSTORMS FROM NRN MO SSWWD ACROSS ERN KS INTO
NRN OK. THIS ACTIVITY WILL BE LOCATED ON THE ERN EDGE OF A 60 TO 80
KT MID-LEVEL JET CREATING STRONG VERTICAL SHEAR PROFILES FAVORABLE
FOR SUPERCELLS. SUPERCELL DEVELOPMENT SHOULD BE RATHER QUICK DUE TO
THE STRONG INSTABILITY IN PLACE WITH VERY LARGE HAIL POSSIBLE WITH
THE MORE DOMINANT CELLS.

THE CURRENT THINKING IS THAT A BROKEN LINE OF INTENSE STORMS WILL
DEVELOP IN THE LATE AFTERNOON FROM NRN MO SSWWD ACROSS ERN KS INTO
NRN OK ON THE WRN EDGE OF THE LOW-LEVEL JET. THE JET SHOULD CREATE
STRONG LOW-LEVEL SHEAR PROFILES FAVORABLE FOR TORNADOES WITH THE
MORE DOMINANT SUPERCELLS. MODEL FORECASTS ALSO SUGGEST STORM MODE
MAY GRADUALLY TRANSITION TO A LINEAR STRUCTURE DURING THE EVENING AS
A LARGE MCS ORGANIZES FROM THE OZARKS SWWD TO THE LOW-ROLLING PLAINS
OF WEST TX. LARGE HAIL AND WIND DAMAGE WILL BE LIKELY WITH THE
STRONGER CELLS ELEMENTS IN THE MCS.

...MID-MS AND OH VALLEYS...
AN UPPER-LEVEL RIDGE IS FORECAST TO MOVE NEWD FROM THE MID-MS VALLEY
INTO THE OH VALLEY TODAY. A LARGE WARM SECTOR SHOULD BE IN PLACE
THIS AFTERNOON FROM MO EWD ACROSS MUCH OF SRN IL...SRN IND AND KY
WHERE FORECAST SOUNDINGS SHOW MODERATE TO STRONG INSTABILITY.
ALTHOUGH LARGE-SCALE ASCENT SHOULD REMAIN QUITE WEAK ACROSS THE
REGION...THE NAM AND GFS SOLUTIONS DO INITIATE A CLUSTER OF
THUNDERSTORMS FROM NEAR ST LOUIS ENEWD TO AROUND INDIANAPOLIS TODAY
BUT DIFFER ON THE TIMING. THE CURRENT THINKING IS THAT ELEVATED
THUNDERSTORMS WILL MOVE ACROSS THE REGION THIS MORNING WITH
SFC-BASED STORM DEVELOPMENT HOLDING OFF UNTIL EARLY THIS AFTERNOON
IN NRN MO MOVING EWD ACROSS THE OH VALLEY DURING THE LATE AFTERNOON.
FORECAST SOUNDINGS ACROSS THE OH VALLEY AT 21Z SHOW 40 TO 50 KT OF
0-6KM SHEAR SUGGESTING VERTICAL SHEAR WILL BE SUFFICIENT FOR
ROTATING STORMS BUT SOME MULTICELL LINE-SEGMENTS MAY ALSO DEVELOP.
STEEP LOW-LEVEL LAPSE RATES...UNIDIRECTIONAL WINDS AND INCREASING
LOW-LEVEL FLOW MAY BE FAVORABLE FOR A WIND DAMAGE THREAT. HAIL WILL
ALSO BE POSSIBLE WITH THE STRONGER UPDRAFTS.

...MID-ATLANTIC...
NORTHWEST FLOW WILL BE IN PLACE ACROSS THE MID-ATLANTIC TODAY AS A
COLD FRONT MOVES SLOWLY SWD ACROSS THE REGION. WARMING SFC TEMPS AND
MODERATE DESTABILIZATION SHOULD RESULT IN SCATTERED THUNDERSTORM
DEVELOPMENT AROUND MIDDAY ACROSS VA AND SRN MD. FORECAST SOUNDINGS
IN NRN VA SHOW MODERATE DEEP LAYER SHEAR WITH UNIDIRECTIONAL WIND
PROFILES SUGGESTING SEVERAL LINE-SEGMENTS WITH WIND DAMAGE POTENTIAL
MAY DEVELOP AND MOVE EWD INTO THE IMMEDIATE COASTAL AREAS BY EARLY
EVENING. HAIL WILL ALSO BE POSSIBLE WITH COVERAGE DEPENDENT UPON THE
AMOUNT OF DESTABILIZATION.

VALID 131200Z - 141200Z

...THERE IS A SLGT RISK OF SVR TSTMS THU ACROSS THE MIDDLE
MISSISSIPPI AND OHIO VALLEYS....

...SYNOPSIS...
MODELS CONTINUE TO INDICATE THAT A SUBTROPICAL RIDGE...NOW BUILDING
ACROSS THE EASTERN GULF OF MEXICO INTO THE SOUTHEASTERN U.S. AND
ADJACENT PORTIONS OF THE WESTERN ATLANTIC...WILL REMAIN STRONG
THROUGH THIS FORECAST PERIOD. UPPER TROUGHING IS EXPECTED TO LINGER
TO ITS WEST...ACROSS CALIFORNIA AND THE CENTRAL/SOUTHERN PLATEAU AND
ROCKIES...BUT A SIGNIFICANT SHORT WAVE IMPULSE EMANATING FROM
IT...INCLUDING THE REMNANTS OF AN EMBEDDED CLOSED LOW...LIKELY WILL
CONTINUE LIFTING AROUND THE PERIPHERY OF THE RIDGE INTO THE UPPER
GREAT LAKES REGION.

A SEASONABLY MOIST...POTENTIALLY UNSTABLE AIR MASS HAS ALREADY
RETURNED TO A BROAD AREA OF THE CENTRAL AND SOUTHEASTERN U.S...AND
THE EVOLVING UPPER PATTERN SHOULD GENERALLY MAINTAIN THIS.
HOWEVER...A COLD FRONT ASSOCIATED WITH THE UPPER TROUGH IS EXPECTED
TO ADVANCE SOUTHWARD THROUGH THE SOUTHERN PLAINS...AND A BIT MORE
SLOWLY EAST/SOUTHEASTWARD THROUGH THE MIDDLE MISSISSIPPI AND OHIO
VALLEYS. THIS FEATURE...PRE-FRONTAL CONVECTIVE BOUNDARIES...AND
CONVECTIVELY GENERATED OR ENHANCED VORTICITY MAXIMA ARE EXPECTED TO
PROVIDE THE FOCUS FOR CONSIDERABLE THUNDERSTORM ACTIVITY
THURSDAY/THURSDAY NIGHT...FROM THE SOUTHERN PLAINS NORTHEASTWARD
THROUGH THE OHIO VALLEY...APPALACHIANS AND PORTIONS OF THE MID
ATLANTIC STATES.

...MIDDLE MISSISSIPPI AND OHIO VALLEYS...
A WEAK FRONTAL WAVE IS EXPECTED TO ACCOMPANY THE UPPER IMPULSE...
MIGRATING FROM UPPER PORTIONS OF THE MIDDLE MISSISSIPPI VALLEY
THROUGH THE GREAT LAKES DURING THE PERIOD. PERHAPS MORE
IMPORTANTLY...MODELS HAVE BEEN SUGGESTIVE THAT AT LEAST WEAK
MID-LEVEL HEIGHT FALLS AND STRENGTHENING WEST SOUTHWESTERLY
LOWER/MID TROPOSPHERIC FLOW WILL OVERSPREAD THE WARM SECTOR...NORTH
AND WEST OF THE OHIO RIVER. IN PARTICULAR...MOST MODELS GENERALLY
INDICATE A 40+ KT 850 MB/60-70 KT 500 MB JET STREAK WILL NOSE
NORTHEASTWARD INTO AND THROUGH THE OHIO VALLEY COINCIDENT WITH
DAYTIME BOUNDARY LAYER DESTABILIZATION. SREF GUIDANCE INDICATES
THAT SURFACE DEW POINTS IN THE MID/UPPER 60S ARE
LIKELY...CONTRIBUTING TO MIXED LAYER CAPE ON THE ORDER OF 2000 J/KG.

IT APPEARS THAT LOW-LEVEL WARM ADVECTION AHEAD OF THE WAVE COULD
CONTRIBUTE TO DISCRETE STORM DEVELOPMENT...POSSIBLY SUPERCELLS WITH
A RISK FOR TORNADOES...NEAR A RETREATING WARM FRONT ACROSS PARTS OF
NORTHERN INDIANA AND OHIO INTO THE NORTH CENTRAL APPALACHIANS BY
EARLY THURSDAY AFTERNOON. THEREAFTER...FORCING ASSOCIATED WITH THE
UPPER IMPULSE SPREADING OUT OF MISSOURI INTO ILLINOIS/INDIANA IS
EXPECTED TO SUPPORT ADDITIONAL STRONG/SEVERE STORM DEVELOPMENT WITH
A TENDENCY TO GROW AND ORGANIZE INTO ONE OR MORE MESOSCALE
CONVECTIVE SYSTEMS. GIVEN THE STRENGTH OF THE DEEP LAYER MEAN
FLOW...THERMODYNAMIC PROFILES PROBABLY WILL BE CONDUCIVE FOR THE
DEVELOPMENT OF POTENTIALLY DAMAGING SURFACE GUSTS...IN ADDITION TO
THE RISK FOR LARGE HAIL. ACTIVITY LIKELY WILL SPREAD EASTWARD
THROUGH MUCH OF THE OHIO VALLEY BEFORE WEAKENING THURSDAY NIGHT.

...SOUTHERN PLAINS INTO THE OZARKS...
UNCERTAINTY IS GROWING CONCERNING SEVERE POTENTIAL FOR THIS PERIOD
DUE TO THE TENDENCY FOR WEAKENING FLOW FIELDS...RISING MID-LEVEL
HEIGHTS...AND POSSIBLE FASTER SOUTHWARD COLD FRONTAL SURGE THAN
EARLIER EXPECTED. THE BOUNDARY LAYER AHEAD OF THE COLD FRONT IS
LIKELY TO REMAIN MODERATE TO STRONGLY UNSTABLE...HOWEVER...SO THE
RISK FOR ISOLATED TO WIDELY SCATTERED LATE AFTERNOON/EVENING STORMS
MAY NOT BE COMPLETELY NEGLIGIBLE.
