AREAS AFFECTED...NERN MS...NRN AL...FAR NWRN GA

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 272154Z - 272300Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...AN INCREASE IN TSTM INTENSITY HAS BEEN NOTED OVER THE PAST
COUPLE HRS ACROSS NERN MS/NWRN AL. THIS ACTIVITY SHOULD CONTINUE
ADVANCING EWD NEARLY PARALLEL TO A WARM FRONT DRAPED ACROSS THE
AREA...BUT INTO A PROGRESSIVELY LESS UNSTABLE ENVIRONMENT.
CONVECTIVE TRENDS ARE BEING CLOSELY MONITORED FOR A POSSIBLE WW.

DISCUSSION...RADAR LOOP SHOWS A SUPERCELL MOVING ACROSS
FRANKLIN/COLBERT COUNTIES IN AL...WHICH IS LIKELY ANCHORED INVOF A
WARM FRONT ANALYZED FROM ROUGHLY 20 N TUP TO 25 NNE GAD TO 20 E
ATL...WITH RECENT REPORTS OF LARGE HAIL ASSOCIATED WITH THIS STORM.
ACTIVITY FARTHER S IN THE WARM SECTOR HAS SHOWN LESS
ORGANIZATION...BUT OCCASIONAL UPWARD PULSES IN INTENSITY HAVE BEEN
NOTED WITH ASSOCIATED POTENTIAL FOR HAIL.

DESPITE FAVORABLE DEEP-LAYER SHEAR IN THE PRESENCE OF A MIDLEVEL
JET...INSTABILITY REMAINS QUITE MARGINAL...AND DECREASES WITH EWD
EXTENT INTO PARTS OF NERN AL AND NWRN GA...WHERE SFC DEW POINTS ARE
ONLY IN THE LOW-TO-MID-50S F. MOISTURE ADVECTION SHOULD INCREASE
LATER THIS EVENING ACROSS ERN PORTIONS OF THE HIGHLIGHTED AREA AND
SHOULD MAINTAIN MARGINAL INSTABILITY BEYOND THE ONSET OF DIURNAL
COOLING. GIVEN THE UNCERTAINTY REGARDING THE POTENTIAL FOR STORM
INTENSITY TO BE MAINTAINED FARTHER E...A WW IS STILL
QUESTIONABLE...BUT CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.

NWS STORM PREDICTION CENTER NORMAN OK
350 PM CDT SAT APR 27 2013

THE NWS STORM PREDICTION CENTER HAS ISSUED A

* TORNADO WATCH FOR PORTIONS OF
EAST CENTRAL ARKANSAS
NORTHERN MISSISSIPPI
SOUTHWEST TENNESSEE

* EFFECTIVE THIS SATURDAY AFTERNOON AND EVENING FROM 350 PM UNTIL
1100 PM CDT.

* PRIMARY THREATS INCLUDE...
SEVERAL TORNADOES POSSIBLE
SEVERAL LARGE HAIL EVENTS WITH A FEW VERY LARGE HAIL EVENTS TO 2
INCHES IN DIAMETER POSSIBLE
SEVERAL DAMAGING WIND GUSTS TO 70 MPH POSSIBLE

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 35 STATUTE
MILES NORTH AND SOUTH OF A LINE FROM 50 MILES EAST SOUTHEAST OF
JACKSON TENNESSEE TO 15 MILES SOUTH OF LITTLE ROCK ARKANSAS. FOR
A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU1).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.

&&

DISCUSSION...THUNDERSTORMS ARE BEGINNING TO INTENSIFY ALONG A WARM
FRONT EXTENDING ROUGHLY FROM A LOW NEAR LIT TO NORTH OF MEM. A
MOIST AND MODERATELY UNSTABLE AIR MASS LIES TO THE SOUTH OF THE
FRONT WITH DEWPOINTS IN THE MID 60S. DEEP EFFECTIVE SHEAR AND
SUFFICIENT LOW LEVEL SHEAR WILL POSE A RISK OF SUPERCELLS CAPABLE OF
LARGE HAIL...DAMAGING WINDS...AND A FEW TORNADOES.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
450. MEAN STORM MOTION VECTOR 24035.

MESOSCALE DISCUSSION 0564
NWS STORM PREDICTION CENTER NORMAN OK
0336 PM CDT SAT APR 27 2013

AREAS AFFECTED...SRN EDWARDS PLATEAU INTO NRN PARTS OF SOUTH CENTRAL
AND SOUTH TX

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 272036Z - 272200Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...THE SRN EDWARDS PLATEAU INTO NRN PORTIONS OF SOUTH CENTRAL
AND SOUTH TX ARE BEING MONITORED FOR CONVECTIVE DEVELOPMENT THIS
AFTERNOON...AND THE POTENTIAL NEED FOR A ONE OR MORE WATCHES.
TRENDS WITH TSTM DEVELOPMENT OVER THE HIGHER TERRAIN OF COAHUILA
MEXICO WILL NEED TO BE MONITORED AS WELL FOR POTENTIAL SEVERE
WEATHER THREAT...IF ACTIVITY CAN REACH THE LOWER RIO GRANDE VALLEY
AREA OF S TX.

DISCUSSION...EARLY-MID AFTERNOON SURFACE ANALYSES INDICATED A FRONT
CONTINUED TO MOVE SLOWLY E/SEWD ACROSS ERN AND CENTRAL TX. AT
20Z...THIS BOUNDARY EXTENDED FROM THE ARKLATEX REGION SWWD TO 50 S
OF KCRS...AND THEN WSWWD ACROSS THE SRN EXTENT OF THE EDWARDS
PLATEAU TO THE RIO GRANDE RIVER VICINITY OF WRN VAL VERDE COUNTY. A
MOIST/WARM BOUNDARY LAYER WITH SURFACE TEMPERATURES IN THE UPPER 70S
TO LOWER 80S ALONG AND S OF THE FRONT IS CONTRIBUTING TO MODERATE
INSTABILITY /MLCAPE 2000-2500 J PER KG/...GIVEN THE PRESENCE OF
STEEP MIDLEVEL LAPSE RATES.

OBJECTIVE ANALYSES INDICATED WEAK DEEP LAYER CONVERGENCE ALONG THE
FRONT WHICH APPEARS TO BE LIMITING THE DEVELOPMENT OF SURFACE BASED
CONVECTION THUS FAR ACROSS THE DISCUSSION AREA. REGIONAL RADAR
IMAGERY SHOWED A COUPLE OF TSTMS HAD DEVELOPED WITHIN A PLUME OF
ELEVATED CONVECTION N OF THE FRONT THIS AFTERNOON. THE MOST RECENT
STORMS COULD BE NEARLY SURFACE BASED IN WILLIAMSON AND TRAVIS
COUNTIES TX...GIVEN ITS LOCATION NEAR THE FRONT. ADDITIONAL STORMS
LOCATED TO THE NW TO W OF THE HOUSTON METRO AREA SHOULD CONTINUE TO
PROPAGATE NWWD LATE THIS AFTERNOON INTO A MORE FAVORABLE CAPE/SHEAR
SPACE SUPPORTIVE OF MORE PERSISTENT/ORGANIZED UPDRAFTS THAT COULD
RESULT IN A HAIL THREAT.

MEANWHILE...IF GREATER COVERAGE OF CONVECTIVE DEVELOPMENT OCCURS
NEAR AND S OF THE FRONT...THE PRESENCE OF STRONG INSTABILITY AND
EFFECTIVE BULK SHEAR OF 30-40 KT WILL SUPPORT ORGANIZED STRONG TO
SEVERE STORMS. THUS...THE DISCUSSION AREA IS BEING MONITORED FOR
THE POTENTIAL ISSUANCE OF ONE OR MORE WATCHES.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0255 PM CDT SAT APR 27 2013

VALID 272000Z - 281200Z

...THERE IS A SLGT RISK OF SVR TSTMS THIS AFTERNOON AND TONIGHT FROM
SW TX TO PARTS OF AR/TN/MS/AL...

...AR/TN/MS/AL...
PRIMARY CHANGE TO THE PREVIOUS OUTLOOK FOR AR/TN/MS/AL WAS A SMALL
WWD EXTENSION OF THE SLGT RISK AREA INTO CNTRL AR. AFTERNOON SURFACE
OBSERVATIONS AND VISIBLE SATELLITE LOOP SHOW THE PRIMARY SURFACE LOW
MOVING EWD FROM W-CNTRL AR INTO CNTRL AR. CUMULUS FIELD IS BEGINNING
TO SHOW SIGNS OF DEEPENING INVOF THIS FEATURE AS TEMPERATURES OVER
SRN AR CONTINUE TO WARM THROUGH THE 70S. GIVEN MODERATE CAPE AND
SUPERCELL WIND PROFILES...ANY STORMS THAT MATURE OVER CNTRL/SRN AR
WILL BE CAPABLE OF PRODUCING LARGE HAIL...DAMAGING WINDS...AND AN
ISOLATED TORNADO.

OTHERWISE...MAJORITY OF THE PREVIOUS OUTLOOK APPEARS TO BE ON TRACK.
SURFACE LOW PRESSURE IS FORECAST TO ADVANCE ENEWD TOWARD THE LOWER
OH VALLEY BY EVENING...WITH A WARM FRONT CURRENTLY ANALYZED FROM SRN
AR INTO NRN MS AND NWRN AL LIFTING NWD INTO WRN/MIDDLE TN...WHILE A
COLD FRONT MOVES EWD INTO THE LOWER MS VALLEY. CONVECTION HAS BEEN
SLOW TO MATURE INTO THUNDERSTORMS THUS FAR DUE IN PART TO CLOUDINESS
ACROSS THE WARM SECTOR. HOWEVER...SHORT-TERM MODEL GUIDANCE
INDICATES DESTABILIZATION WILL CONTINUE...LEADING TO SCATTERED
THUNDERSTORM COVERAGE BY LATE AFTERNOON/EVENING. BUOYANCY AND SHEAR
WILL BE FAVORABLE FOR ORGANIZED THUNDERSTORM DEVELOPMENT...INCLUDING
SUPERCELLS...WHICH WILL POSE A RISK FOR LARGE HAIL...DAMAGING
WINDS...AND A COUPLE OF TORNADOES. DUE TO THE SLOW EVOLUTION OF
THUNDERSTORM DEVELOPMENT THIS AFTERNOON...CONFIDENCE HAS DECREASED
IN THE OCCURRENCE OF A CONCENTRATED SWATH OF LARGE HAIL OVER SWRN
TN/NRN MS. THEREFORE...THE 30 PERCENT HAIL PROBABILITY HAS BEEN
ELIMINATED.

...LA INTO E-CNTRL/SERN TX...
STRONG DESTABILIZATION IS OCCURRING ACROSS E-CNTRL/SERN TX...WITH A
CLUSTER OF STORMS RECENTLY DEVELOPING W OF HOU. COVERAGE IS EXPECTED
TO INCREASE THIS AFTERNOON ACROSS THE AREA...AND WILL POSE A LARGE
HAIL/DAMAGING WIND THREAT GIVEN THE MOIST AND UNSTABLE ENVIRONMENT
THAT IS CURRENTLY OBSERVED.

...S-CNTRL TX...
A SURFACE FRONTAL BOUNDARY REMAINS QUASI-STATIONARY FROM ROUGHLY 20
N OF AUS WWD ACROSS THE EDWARDS PLATEAU. SKIES HAVE PARTIALLY
CLEARED ALONG THIS BOUNDARY...WHICH IS AIDING IN TEMPERATURES
WARMING INTO THE 80S. AS A RESULT...CONVECTIVE INHIBITION IS SLOWLY
WEAKENING. ALONG AND S OF THE FRONT...SURFACE DEWPOINTS ARE IN THE
LOW TO MID 60S. THIS MOISTURE COMBINED WITH STEEP MIDLEVEL LAPSE
RATES IS CONTRIBUTING TO MLCAPE VALUES IN EXCESS OF 2000 J/KG. THE
17Z HRRR CONTINUES TO SHOW A CLUSTER OF STORMS FORMING ALONG THE
FRONT BY LATE AFTERNOON. GIVEN THE STRONG INSTABILITY COUPLED WITH
LOW-LEVEL ELYS OCCURRING BENEATH 30+ KT MIDLEVEL WLYS...ENVIRONMENT
WILL BE SUPPORTIVE OF SPLITTING SUPERCELLS CAPABLE OF PRODUCING VERY
LARGE HAIL.

FARTHER S...STRATUS HAS BEEN SLOW TO ERODE INVOF THE RIO
GRANDE...WHICH IS DELAYING ROBUST BOUNDARY LAYER DESTABILIZATION.
THIS YIELDS UNCERTAINTY IN WHETHER STORMS THAT MAY INITIATE OVER THE
HIGHER TERRAIN IN MEXICO WILL BE ABLE TO PERSIST EWD INTO S TX.
THUS...THREAT FOR LARGE HAIL/DAMAGING WINDS IS MORE CONDITIONAL
COMPARED TO LOCATIONS CLOSER TO THE FRONT.

..GARNER.. 04/27/2013

.PREV DISCUSSION... /ISSUED 1110 AM CDT SAT APR 27 2013/

...AR/TN/MS...
MORNING SATELLITE IMAGERY SHOWS A COMPACT UPPER LOW OVER WESTERN
MO...AND A SHORTWAVE TROUGH EXTENDING SOUTHWARD FROM THE LOW INTO
WESTERN AR. THE TROUGH WILL ROTATE EASTWARD TODAY INTO THE MID MS
VALLEY AND PROVIDE LARGE SCALE ASCENT FOR THE DEVELOPMENT OF
SCATTERED SHOWERS AND THUNDERSTORMS. SURFACE ANALYSIS INDICATES A
LOW OVER SOUTHEAST OK AND A WARM FRONT EXTENDING EASTWARD ACROSS
CENTRAL AR INTO SOUTHWEST TN. INCREASING BREAKS IN THE CLOUDS TO
THE SOUTH OF THE WARM FRONT WILL HELP TO SLOWLY DESTABILIZE THE AIR
MASS...WHILE DEWPOINTS CLIMB INTO THE MID 60S. THIS SCENARIO SHOULD
RESULT IN A FOCUSED AREA OF STRONG/SEVERE THUNDERSTORM DEVELOPMENT
LATER THIS AFTERNOON AND EVENING ACROSS PARTS OF EASTERN AR/WEST
TN/NORTHERN MS. FORECAST SOUNDINGS SHOW STRONG EFFECTIVE SHEAR AND
0-3KM HELICITY VALUES OF 150-250 M2/S2. THESE PARAMETERS COUPLED
WITH SUFFICIENT INSTABILITY WILL PROMOTE THE RISK OF SUPERCELLS
CAPABLE OF LARGE HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES.
ACTIVITY WILL SPREAD EASTWARD THROUGH THE EVENING INTO MIDDLE TN AND
NORTHWEST AL BEFORE WEAKENING.

...LA/EAST TX...
A COLD FRONT CURRENTLY EXTENDS FROM THE AFOREMENTIONED LOW OVER
SOUTHEAST OK INTO EAST TX. THIS BOUNDARY IS EXPECTED TO SAG
SOUTHEASTWARD INTO NORTHWEST LA BY LATE AFTERNOON. MODEL SOLUTIONS
ARE IN AGREEMENT THAT THE CAPPING INVERSION SHOULD WEAKEN THROUGH
THE DAY LEADING TO SCATTERED THUNDERSTORMS ALONG THE FRONT. LOW
LEVEL SHEAR IS EXPECTED TO BE RATHER WEAK...BUT SUFFICIENT DEEP
LAYER FLOW AND MODERATE INSTABILITY WILL PROMOTE STRONG UPDRAFTS
CAPABLE OF HAIL AND GUSTY WINDS.

...SOUTH CENTRAL TX...
THE COLD FRONT IS FORECAST TO EXTEND FROM AUS WESTWARD ACROSS THE
HILL COUNTRY LATER THIS AFTERNOON. MORNING STRATUS TO THE SOUTH OF
THE FRONT IS SLOWLY BURNING OFF...WHICH SHOULD HELP TO YIELD
AFTERNOON MLCAPE VALUES OF 2500 J/KG. DEEP WEAK EASTERLY LOW LEVEL
FLOW BENEATH MODERATELY STRONG WESTERLY FLOW AT MID LEVELS WILL
PROVIDE SUFFICIENT SHEAR FOR ORGANIZED/SUPERCELL STORMS CAPABLE OF
LARGE HAIL AND DAMAGING WINDS.

AREAS AFFECTED...NRN/CNTRL MS...NWRN AL...WRN TN...ERN AR

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 271855Z - 272100Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...SEVERE TSTMS SHOULD DEVELOP ACROSS PARTS OF THE MID-SOUTH
TOWARDS THE TN VALLEY BY LATE-AFTERNOON. A TORNADO AND PERHAPS A
SEVERE THUNDERSTORM WATCH WILL BECOME NECESSARY AT SOME POINT...BUT
CONFIDENCE IS LOW ON TIMING OF WW ISSUANCE THIS AFTERNOON.

DISCUSSION...18Z SURFACE ANALYSIS PLACED A 1015 MB CYCLONE 30 W KHOT
WITH A WARM FRONT EXTENDING EWD TO NEAR KMEM TO KHSV AND A COLD
FRONT EXTENDING SWWD INTO NERN TX. ABUNDANT CLOUD COVERAGE WAS
PREVALENT ALONG THE FRONTAL ZONES. NEVERTHELESS...SURFACE
TEMPERATURES HAD WARMED THROUGH THE 70S IN MUCH OF THE WARM SECTOR
INTO THE LOWER 80S ACROSS CNTRL/SRN MS...WHILE DEW POINTS HAVE HELD
IN THE MIDDLE 60S. THIS IS FOSTERING THE INCREASING PRESENCE OF A
MODERATELY BUOYANT AIR MASS.

CONVERGENCE ALONG PRIMARILY THE COLD FRONT...AS WELL AS BANDS OF
CONFLUENCE WITHIN THE WARM SECTOR WILL YIELD INCREASING TSTM
COVERAGE AS THE AIR MASS CONTINUES TO DESTABILIZE. WITH A BELT OF
STRONG 700-500 MB FLOW ATTENDANT TO THE COMPACT SHORTWAVE IMPULSE
MOVING EWD ACROSS SRN MO...SETUP SHOULD YIELD SEVERAL
SUPERCELLS/MULTICELL CLUSTERS CAPABLE OF LARGE HAIL AND DAMAGING
WIND. 0-1 KM SHEAR OF 15-25 KT WILL ALSO SUPPORT A RISK FOR A FEW
TORNADOES...MOST LIKELY NEAR THE WARM FRONT FROM ERN AR INTO WRN TN.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1148 AM CDT SAT APR 27 2013

VALID 281200Z - 291200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
AN UPPER LEVEL SHORTWAVE TROUGH IS FORECAST TO SHIFT EWD ACROSS THE
OH VALLEY ON SUNDAY. AS THIS OCCURS...IT WILL BECOME DISLOCATED FROM
A POSITIVE TILT VORTICITY STREAMER EXTENDING SWWD INTO CNTRL TX AND
NRN MEXICO. AT THE SURFACE...LOW PRESSURE WILL BE POSITIONED OVER
THE LOWER/MID OH VALLEY AT THE START OF THE FORECAST PERIOD...WITH A
COLD FRONT TRAILING TO THE SW INTO CNTRL LA AND THEN WWD INTO CNTRL
TX. AS THE DAY PROGRESSES...THE LOW WILL WEAKEN AS IT LIFTS NEWD
INTO OH...AND THE TRAILING COLD FRONT WILL DISSIPATE BY LATE
AFTERNOON. MEANWHILE OVER THE NRN CONUS...A COLD FRONT ASSOCIATED
WITH A SURFACE CYCLONE OVER CANADA WILL MOVE SWD ACROSS THE
NRN/CNTRL PLAINS...AND WILL SERVE AS A FOCUS FOR THUNDERSTORM
DEVELOPMENT DURING THE AFTERNOON AND NIGHT.

...SRN HIGH PLAINS...
SELY LOW-LEVEL WINDS OVER MUCH OF TX WILL ENCOUNTER SWLY FLOW OVER
THE SRN HIGH PLAINS SUNDAY AFTERNOON...AND WILL RESULT IN A WEAK
ZONE OF SURFACE CONFLUENCE ORIENTED SWWD FROM WRN OK INTO W-CNTRL
TX. DEWPOINTS IN THE 30S TO LOW 40S COMBINED WITH TEMPERATURES IN
THE LOW 80S AND STEEP LOW TO MIDLEVEL LAPSE RATES WILL CONTRIBUTE
TOWARD MLCAPE VALUES FROM 500-1500 J/KG ALONG AND E OF THE
CONFLUENCE ZONE. THE UNSTABLE ENVIRONMENT COMBINED WITH A MINOR
DISTURBANCE MOVING SWD INTO THE AREA DURING THE AFTERNOON MAY BE
SUFFICIENT FOR ISOLATED TO SCATTERED THUNDERSTORM DEVELOPMENT.
THOUGH VERTICAL WIND PROFILES WILL BE UNFAVORABLE FOR ORGANIZED
THUNDERSTORM DEVELOPMENT...ISOLATED DAMAGING WIND GUSTS AND
MARGINALLY SEVERE HAIL CANNOT BE RULED OUT.

...CNTRL/ERN KY...SRN OH...
AS AN UPPER LEVEL SHORTWAVE TROUGH MOVES ENEWD ACROSS THE OH VALLEY
DURING THE AFTERNOON...A MIDLEVEL DRYSLOT IS FORECAST TO SPREAD
ACROSS CNTRL/ERN KY AND SRN OH. ANY CLEARING THAT TAKES PLACE WOULD
AID IN DESTABILIZING THE BOUNDARY LAYER...AND WITH 50S DEWPOINTS
PRESENT ACROSS THE AREA...COULD POTENTIALLY BOOST MLCAPE VALUES TO
500-1000 J/KG. ASCENT ASSOCIATED WITH THE UPPER DISTURBANCE COMBINED
WITH WEAKENING SURFACE CONVERGENCE TRAILING A LOW OVER ERN IND/WRN
OH MAY RESULT IN THE DEVELOPMENT OF A BROKEN LINE OF STORMS. LOW TO
MIDLEVEL SWLY FLOW ON THE ORDER OF 20-40 KT WILL BE MARGINALLY
FAVORABLE FOR ORGANIZED THUNDERSTORM DEVELOPMENT POSING A LOW-END
THREAT FOR SEVERE WIND/HAIL.

...SERN STATES...
THUNDERSTORMS ARE FORECAST TO BE ONGOING AT THE START OF THE PERIOD
FROM MIDDLE TN SWD INTO PORTIONS OF MS/AL. MORNING FORECAST
SOUNDINGS ACROSS THESE AREAS INDICATE SUFFICIENT CAPE AND VERTICAL
WIND SHEAR WILL BE PRESENT FOR AN ISOLATED DAMAGING WIND THREAT.
THEREAFTER...LAPSE RATES ARE EXPECTED TO WEAKEN SIGNIFICANTLY IN THE
LOW AND MIDLEVELS. THOUGH SHOWERS AND THUNDERSTORMS WILL LIKELY
CONTINUE THROUGH THE AFTERNOON...THE SEVERE WEATHER THREAT IS
FORECAST TO BECOME INCREASINGLY MARGINAL.

...SRN TX...
UNCERTAINTY EXISTS IN HOW MUCH RESIDUAL CLOUD COVER PRODUCED BY
OVERNIGHT CONVECTION WILL EXIST OVER SRN TX ON SUNDAY. IF HEATING
CAN OCCUR AND TEMPERATURES WARM INTO THE 80S...THEN LOW TO MID 60S
DEWPOINTS WILL AID IN MLCAPE VALUES NEAR 1000 J/KG. ESELY WINDS
OCCURRING OVER THE LOWEST 1 KM SURMOUNTED BY 30-40 KT WLY FLOW AT 6
KM WILL RESULT IN LONG HODOGRAPHS FAVORABLE FOR SPLITTING STORMS.
LATEST MODEL GUIDANCE INDICATES THUNDERSTORMS MAY MOVE EWD OUT OF
MEXICO AND INTO SRN TX DURING THE AFTERNOON AND EVENING. IF THIS
SCENARIO OCCURS...THEN ISOLATED LARGE HAIL WOULD BE POSSIBLE.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1110 AM CDT SAT APR 27 2013

VALID 271630Z - 281200Z

...THERE IS A SLGT RISK OF SVR TSTMS THIS AFTERNOON AND TONIGHT FROM
SW TX TO PARTS OF TN/MS/AL...

...AR/TN/MS...
MORNING SATELLITE IMAGERY SHOWS A COMPACT UPPER LOW OVER WESTERN
MO...AND A SHORTWAVE TROUGH EXTENDING SOUTHWARD FROM THE LOW INTO
WESTERN AR. THE TROUGH WILL ROTATE EASTWARD TODAY INTO THE MID MS
VALLEY AND PROVIDE LARGE SCALE ASCENT FOR THE DEVELOPMENT OF
SCATTERED SHOWERS AND THUNDERSTORMS. SURFACE ANALYSIS INDICATES A
LOW OVER SOUTHEAST OK AND A WARM FRONT EXTENDING EASTWARD ACROSS
CENTRAL AR INTO SOUTHWEST TN. INCREASING BREAKS IN THE CLOUDS TO
THE SOUTH OF THE WARM FRONT WILL HELP TO SLOWLY DESTABILIZE THE AIR
MASS...WHILE DEWPOINTS CLIMB INTO THE MID 60S. THIS SCENARIO SHOULD
RESULT IN A FOCUSED AREA OF STRONG/SEVERE THUNDERSTORM DEVELOPMENT
LATER THIS AFTERNOON AND EVENING ACROSS PARTS OF EASTERN AR/WEST
TN/NORTHERN MS. FORECAST SOUNDINGS SHOW STRONG EFFECTIVE SHEAR AND
0-3KM HELICITY VALUES OF 150-250 M2/S2. THESE PARAMETERS COUPLED
WITH SUFFICIENT INSTABILITY WILL PROMOTE THE RISK OF SUPERCELLS
CAPABLE OF LARGE HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES.
ACTIVITY WILL SPREAD EASTWARD THROUGH THE EVENING INTO MIDDLE TN AND
NORTHWEST AL BEFORE WEAKENING.

...LA/EAST TX...
A COLD FRONT CURRENTLY EXTENDS FROM THE AFOREMENTIONED LOW OVER
SOUTHEAST OK INTO EAST TX. THIS BOUNDARY IS EXPECTED TO SAG
SOUTHEASTWARD INTO NORTHWEST LA BY LATE AFTERNOON. MODEL SOLUTIONS
ARE IN AGREEMENT THAT THE CAPPING INVERSION SHOULD WEAKEN THROUGH
THE DAY LEADING TO SCATTERED THUNDERSTORMS ALONG THE FRONT. LOW
LEVEL SHEAR IS EXPECTED TO BE RATHER WEAK...BUT SUFFICIENT DEEP
LAYER FLOW AND MODERATE INSTABILITY WILL PROMOTE STRONG UPDRAFTS
CAPABLE OF HAIL AND GUSTY WINDS.

...SOUTH CENTRAL TX...
THE COLD FRONT IS FORECAST TO EXTEND FROM AUS WESTWARD ACROSS THE
HILL COUNTRY LATER THIS AFTERNOON. MORNING STRATUS TO THE SOUTH OF
THE FRONT IS SLOWLY BURNING OFF...WHICH SHOULD HELP TO YIELD
AFTERNOON MLCAPE VALUES OF 2500 J/KG. DEEP WEAK EASTERLY LOW LEVEL
FLOW BENEATH MODERATELY STRONG WESTERLY FLOW AT MID LEVELS WILL
PROVIDE SUFFICIENT SHEAR FOR ORGANIZED/SUPERCELL STORMS CAPABLE OF
LARGE HAIL AND DAMAGING WINDS.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0754 AM CDT SAT APR 27 2013

VALID 271300Z - 281200Z

...THERE IS A SLGT RISK OF SVR TSTMS THIS AFTERNOON INTO EARLY
TONIGHT FROM SW TX TO NW MS/SW TN...

...SYNOPSIS...
A WEAK MIDLEVEL LOW OVER SE KS...AND A TRAILING SHORTWAVE TROUGH
OVER CENTRAL/ERN OK...WILL MOVE EWD TO THE TN AND LOWER OH VALLEY
REGIONS BY EARLY SUNDAY. AT THE SURFACE...A WEAK LOW IN SE OK WILL
TRANSLATE NEWD TO THE LOWER OH VALLEY ALONG A PRE-EXISTING
BAROCLINIC ZONE...IN ADVANCE OF THE MIDLEVEL TROUGH. A SWATH OF
MID-UPPER 60S BOUNDARY LAYER DEWPOINTS HAS SPREAD INLAND ACROSS LA
AND SRN/ERN TX. THIS MOIST SECTOR WILL EXPAND TODAY ACROSS SE
AR/NRN MS/NW AL AND WRN/MIDDLE TN...IMMEDIATELY S OF THE FRONT THAT
WILL BE REINFORCED BY CONVECTION THIS MORNING.

...SE AR/NW MS/SW TN THIS AFTERNOON INTO EARLY TONIGHT...
MLCAPE VALUES ARE EXPECTED TO REACH THE 1500-2500 J/KG RANGE BY
AFTERNOON WITH SURFACE HEATING ON THE SRN FRINGE OF THE MORNING
CLOUDS/CONVECTION...AS LOW-LEVEL MOISTURE INCREASES FROM THE S/SW.
MEANWHILE...DEEP-LAYER VERTICAL SHEAR WILL BE FAVORABLE FOR
ORGANIZED CLUSTERS/LINE SEGMENTS...AS WELL AS SUPERCELLS...AS THE
SHORTWAVE TROUGH PIVOTS EWD FROM OK TO AR. THE PRIMARY SEVERE RISKS
WILL BE DAMAGING GUSTS AND LARGE HAIL WITH A BAND OF STORMS NEAR THE
SURFACE LOW AND ALONG THE TRAILING COLD FRONT THIS AFTERNOON THROUGH
EARLY TONIGHT. THOUGH LOW-LEVEL SHEAR WILL NOT BE PARTICULARLY
STRONG...SOME ENHANCEMENT TO HODOGRAPH CURVATURE AND RESULTANT
EFFECTIVE SRH NEAR 200 M2/S2 COULD SUPPORT AN ISOLATED TORNADO THIS
AFTERNOON/EVENING FROM ERN AR INTO NW MS/SW TN.

...TX BIG BEND/RIO GRANDE VALLEY THIS AFTERNOON INTO TONIGHT...
BOUNDARY LAYER DEWPOINTS IN THE 68-70 F RANGE HAVE OVERSPREAD S AND
SE TX THIS MORNING...BENEATH A RESIDUAL STEEP MIDLEVEL LAPSE RATE
PLUME. THOUGH THE PRIMARY SYNOPTIC WAVE WILL PROGRESS AWAY FROM
THIS AREA THROUGH TONIGHT...A BAND OF 30-40 KT WSWLY MIDLEVEL FLOW
WILL PERSIST INVOF THE SLOW-MOVING FRONT ACROSS SW AND CENTRAL TX.
THUS...THE COMBINATION OF BUOYANCY AND VERTICAL SHEAR WILL BE
FAVORABLE FOR ORGANIZED CLUSTERS AND SUPERCELLS AS STORMS FORM LATE
THIS AFTERNOON ALONG THE FRONT FROM SW INTO CENTRAL TX...AS WELL AS
OVER THE HIGH TERRAIN IN NE MEXICO. LARGE HAIL WILL BE THE PRIMARY
RISK INITIALLY WITH SPLITTING STORMS. OUTFLOW MERGERS AND UPSCALE
GROWTH SHOULD SUPPORT SOME INCREASE IN THE DAMAGING WIND RISK THIS
EVENING INTO EARLY TONIGHT...AS STORMS PROPAGATE SEWD INTO S TX
BEFORE WEAKENING.

...E TX AREA THIS AFTERNOON...
THOUGH LARGE SCALE FORCING FOR ASCENT MAY REMAIN RATHER WEAK THROUGH
THIS AFTERNOON...SUBSTANTIAL SURFACE HEATING AND LOW-LEVEL
CONVERGENCE ALONG A SURFACE COLD FRONT MAY PROMOTE THUNDERSTORM
DEVELOPMENT. MLCAPE WILL POTENTIALLY REACH 2500 J/KG WITH STEEP
MIDLEVEL LAPSE RATES...THOUGH LOW-LEVEL FLOW/SHEAR WILL REMAIN WEAK.
THE NET RESULT WILL BE AN ENVIRONMENT SUPPORTIVE OF LARGE HAIL...AND
THERE WILL BE ENOUGH OF A RISK FOR THUNDERSTORM INITIATION TO
WARRANT EXPANSION OF THE CATEGORICAL SLIGHT RISK INTO THIS AREA FOR
THIS AFTERNOON.
