THE SEVERE WEATHER THREAT FOR TORNADO WATCH
215...217...221...CONTINUES.

SVR CONVECTION...INCLUDING SEVERAL POTENTIALLY TORNADIC
SUPERCELLS...CONTINUES TO INCREASE IN COVERAGE ACROSS DISCUSSION
AREA FROM ERN OK TO MS RIVER NEAR MEM.

WARM-SECTOR ENVIRONMENT WILL REMAIN FAVORABLE FOR TORNADIC
SUPERCELLS. IN FACT...PRE-STORM LOW-LEVEL SHEAR PROFILES ARE
EXPECTED TO BECOME VERY FAVORABLE FOR BOTH SIGNIFICANT/DESTRUCTIVE
TORNADOES AND WIND DAMAGE DURING NEXT 3-4 HOURS AS LLJ STRENGTHENS
JUST ABOVE SFC...SUBSTANTIALLY BOOSTING LOW-LEVEL SHEAR AND SRH.
LARGE/DESTRUCTIVE HAIL ALSO IS LIKELY FROM INDIVIDUAL SUPERCELLS.

SFC MESOANALYSIS SHOWS LOW OVER ERN OK JUST W FSM...COLD FRONT SWWD
ACROSS LAMAR COUNTY TX...QUASISTATIONARY FRONTAL ZONE CURVING NEWD
OVER NWRN AND EXTREME N-CENTRAL AR. FRONT BECOMES COLD FRONT AGAIN
FROM NERN AR NEWD ACROSS SERN MO. THOSE FRONTAL ZONES WILL ACT AS
NRN/WRN BOUNDS FOR SFC-BASED EFFECTIVE INFLOW PARCELS...ALTHOUGH
TSTMS TO THEIR N AND W ACROSS SERN KS/NERN OK/SWRN MO REGION WILL BE
IN FAVORABLE ELEVATED SHEAR AND BUOYANCY FOR LARGE HAIL. IN REGIME
OF STG LOW-LEVEL WAA AND SHEAR SE OF FRONTAL ZONE...OUTFLOW
BOUNDARIES PRODUCED BY ONGOING CONVECTION OVER AR MAY MIX/ADVECT
AWAY RATHER QUICKLY...BUT ALSO CAN SUPPLY ADDITIONAL LOW-LEVEL
VORTICITY/SHEAR ABOVE ALREADY STRONG ENVIRONMENTAL VALUES. MODIFIED
RAOBS AND RUC SOUNDINGS INDICATE MLCAPE RANGING FROM 3000 J/KG OVER
CONVECTIVELY UNPERTURBED AIR MASS OF CENTRAL/SRN AR...NARROWING TO
CORRIDOR OF 1500-2500 J/KG MLCAPE NEWD TOWARD LOWEST OH VALLEY.
EFFECTIVE SHEAR MAGNITUDES 50-60 KT AND 0-1 KM SRH 150-300 J/KG ARE
COMMON...WITH SRH FCST TO INCREASE SUBSTANTIALLY AFTER 00Z BENEATH

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 215...220...CONTINUES.

CONTINUE WWS..ESPECIALLY S AND E OF METROPLEX. WHILE COLD FRONT HAS
PASSED THROUGH DFW AREA...SVR TSTMS WITH LARGE HAIL STILL ARE
POSSIBLE OVER THAT AREA. SIGNIFICANT/DAMAGING TORNADO THREAT MAY
INCREASE OVER PARTS OF NE TX...SWRN AR AND NRN LA THROUGH REMAINDER
EVENING.

SEVERAL SUPERCELLS...SOME WITH HISTORY OF DAMAGING TORNADOES BETWEEN
CRS-TYR...WILL MOVE EWD TO ENEWD ACROSS NE TX INTO ENVIRONMENT
CHARACTERIZED BY STRENGTHENING LOW-LEVEL SHEAR. ADDITIONAL
DEVELOPMENT NEAR ACT...ALONG WITH ANY TSTMS THAT MAY EVOLVE FROM
DEEP TOWERS EVIDENT IN VIS IMAGERY FARTHER S ALONG DRYLINE TO N OF
SAT...ALSO MAY POST TORNADO RISK AS THEY MOVE EWD INTO ENVIRONMENT
THAT WILL BE CHARACTERIZED BY STRENGTHENING LOW-LEVEL SHEAR AND
LOWERING LCL THROUGH EVENING. THIS ACTIVITY WILL BEGIN TO AFFECT
NRN LA BEFORE 01Z. ALTHOUGH PRE-STORM/WARM-SECTOR MLCAPE WILL
DECREASE SOMEWHAT FROM CURRENT 2500-3500 J/KG VALUES...LOW-LEVEL
THETAE WILL MAINTAIN MODERATELY TO VERY UNSTABLE PROFILE AND
SFC-BASED EFFECTIVE INFLOW PARCELS. MEANWHILE...HODOGRAPHS WILL
ENLARGE DUE TO STRENGTHENING LLJ...RESULTING IN EXTREME 0-1 KM SRH
OF AOA 500 J/KG OVER NE TX NEAR AND N OF ACT-LFK LINE...TRENDING TO
STILL-FAVORABLE 200-300 J/KG ACROSS MUCH OF WW 220. CONVECTIVE
COVERAGE WILL BECOME MORE SPARSE WITH SWD EXTENT THROUGH WW
220...HOWEVER ANY SUSTAINED TSTMS THAT CAN DEVELOP WILL POST RISK OF
LARGE/DAMAGING HAIL AND TORNADOES.

ADDITIONAL LEFT SPLITS WITH LARGE HAIL ALSO ARE
POSSIBLE...ESPECIALLY FOR ANOTHER 2-3 HOURS UNTIL LLJ SUBSTANTIALLY
ENLARGES LOW-LEVEL HODOGRAPHS AND REMOVES NEGATIVE SRH.

VALID 270100Z - 271200Z

...THERE IS A HIGH RISK OF SVR TSTMS FROM NERN TX/SERN OK INTO NWRN

...THERE IS A MDT RISK OF SVR TSTMS FROM NERN TX NEWD INTO TN AND

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS MUCH OF THE LOWER MS
VALLEY NEWD INTO THE OH VALLEY...

...THERE IS A SLGT RISK OF SVR TSTMS FROM NRN VA INTO ERN PA/NY...

...SYNOPSIS...
A STRONG UPPER TROUGH/JET CONTINUES TO DIG SEWD INTO THE SRN
PLAINS...AND WILL CONTINUE INTO THE LOWER MS VALLEY BY WED MORNING.
AT THE SURFACE...LOW PRESSURE WAS CENTERED OVER NWRN TX...WITH A
SECONDARY LOW OVER SWRN AR. SEVERAL ONGOING CLUSTERS OF SEVERE
THUNDERSTORMS EXTENDED FROM NERN TX INTO WRN KY/TN/NRN MS...AND THE
ENTIRE REGION SHOULD REMAIN ACTIVE THROUGH THE EVENING AND OVERNIGHT
AS FORCING WITH THE UPPER TROUGH INCREASES.

...NERN TX/SERN OK EWD ACROSS AR AND INTO WRN TX/NWRN MS...
ONE CLUSTER OF SUPERCELLS WITH A STRONG TORNADO THREAT WAS OVER NERN
TX AND INTO FAR NWRN LA AT 01Z. THE ENVIRONMENT IS VERY SUPPORTIVE
OF TORNADOES...AS THE 00Z SHV SOUNDING INDICATES WITH 300-400
EFFECTIVE SRH...AND A VERY MOIST AND UNSTABLE PROFILE. STORMS NEAR
AND TO THE S OF SHV HAVE SHOWN VERY GOOD STRUCTURE FOR LONG LIVED
TORNADIC SUPERCELLS CAPABLE OF LONG TRACKED TORNADOES. THESE STORMS
WILL LIKELY PERSIST AND TRAVEL NEWD ACROSS NRN LA...AND EVENTUALLY
INTO SERN AR AND NWRN MS LATER THIS EVENING. AS SUCH...HAVE EXPANDED
THE HIGH RISK SWD TO ENCOMPASS MORE OF NRN LA. FOR MORE INFORMATION
REFERENCE MESOSCALE DISCUSSIONS 601 AND 602.

...SERN MO...WRN KY...SRN IL/IND...
ANOTHER CLUSTER OF SEVERE STORMS EVOLVED FROM EARLIER CONVECTION
OVER AR...AND HAS MOVED INTO NWRN MS AND WRN TN. OTHER ISOLATED
ACTIVITY WAS ONGOING OVER WRN KY...WHERE LOW LEVEL SHEAR AND
MOISTURE WILL INCREASE THIS EVENING. HAVE EXTENDED THE MDT RISK NWD
INTO WRN KY/SRN IL IN PART DO TO THE ONGOING SUPERCELL THREAT...BUT
ALSO THE THREAT OF ADDITIONAL DEVELOPMENT ASSOCIATED WITH A
DEEPENING SECONDARY SURFACE LOW LATER TONIGHT.

...PA/NY...
00Z SOUNDINGS FROM THE REGION SHOW MARGINAL INSTABILITY BUT
RELATIVELY STRONG SHEAR PROFILES IN PLACE. STEEP LOW LEVEL LAPSE
RATES WERE ALSO IN PLACE WITH LITTLE CAPPING. HOWEVER...WITH
TIME...SOME BOUNDARY LAYER STABILIZATION WILL OCCUR WITH LOSS OF
HEATING. SHEAR PROFILES WILL STILL ENABLE ONGOING CONVECTION TO
PERSIST FOR SEVERAL HOURS...BUT A GENERAL THINNING OUT OF COVERAGE
SHOULD COMMENCE AFTER SUNSET. FOR MORE INFORMATION SEE MESOSCALE
DISCUSSION 600 AND 603.

...IND INTO WRN OH...
A LARGE AREA OF STORMS ASSOCIATED WITH RAPID WARM ADVECTION AND A
DEEPENING SURFACE LOW SHOULD TRANSLATE NEWD OUT OF AR AND INTO THE
LOWER OH VALLY THIS EVENING. WITH AN INTENSE 60+ KT SLY LOW LEVEL
JET AND NWD MOISTURE ADVECTION...THIS SHOULD PROVIDE AMPLE FORCING
FOR SEVERE STORMS INCLUDING A FEW TORNADOES AND VERY STRONG WINDS.
THIS THREAT MAY EVENTUALLY AFFECT MUCH OF SRN IND INTO WRN OH BY WED
MORNING.
