AREAS AFFECTED...N-CNTRL/NERN TX AND NWRN LA

CONCERNING...SEVERE THUNDERSTORM WATCH 137...138...

VALID 150456Z - 150630Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
137...138...CONTINUES.

CONVECTION WILL CONTINUE BUILDING SWD ACROSS N-CNTRL TX IN RESPONSE
TO STRONG LOW-LEVEL CONVERGENCE ALONG A COLD FRONT OVERTAKING A
DRYLINE. THE COMBINATION OF MLCAPE VALUES OF 1000-2000 J/KG AND
EFFECTIVE BULK SHEAR MAGNITUDES AOA 50 KT IMMEDIATELY AHEAD OF THE
FRONT WILL PROMOTE ORGANIZED LINEAR CONVECTIVE STRUCTURES WITH AN
ATTENDANT THREAT FOR DMGG WINDS AND LARGE HAIL. WHILE EFFECTIVE SRH
VALUES AOA 300 M2/S2 COULD SUPPORT A BRIEF TORNADO THREAT...THE
UNDERCUTTING NATURE OF THE SYNOPTIC BOUNDARY AND ANTICIPATED LINEAR
CONVECTIVE MODE WILL BE ASSOCIATED WITH DMGG STRAIGHT-LINE WINDS AS
THE PRIMARY THREAT. LARGE HAIL WILL ALSO BE A CONCERN WITH STEEP
MID-LEVEL LAPSE RATES AROUND 8 C/KM IMPINGING ON THE DEVELOPING
CONVECTION. STRONG WLY CLOUD-BEARING FLOW WILL ALLOW STORMS TO
SPREAD INTO NERN TX AND EVENTUALLY NWRN LA DURING THE OVERNIGHT
HOURS...AND THUS SVR TSTM WATCH 138 HAS BEEN ISSUED DOWNSTREAM OF WW
137.

STORMS...PERHAPS SFC-BASED...MAY FORM IN MOISTENING 50+ KT CONFLUENT
LOW-LVL FLOW OVER CNTRL MS. STRENGTH OF LOW-LVL AND DEEP
SHEAR...DEGREE OF FORCING FOR ASCENT...AND PRESENCE OF EXISTING

AREAS AFFECTED...NRN LA...AR..THE MO BOOTHEEL...WRN AR AND NW MS

CONCERNING...TORNADO WATCH 136...

VALID 150627Z - 150800Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 136 CONTINUES.

A NEW WW WILL LIKELY BE NEEDED WITHIN THE HOUR.

STRONG FORCING FOR UPWARD VERTICAL MOTION...EAST OF A SIGNIFICANT
CLOSED LOW/UPPER TROUGH SLOWLY MOVING EASTWARD THROUGH THE CENTRAL
PLAINS...APPEARS LIKELY TO MAINTAIN A STRONG/SEVERE MESOSCALE
CONVECTIVE SYSTEM ACROSS ARKANSAS AND NORTHERN LOUISIANA INTO UPPER
PORTIONS OF THE LOWER MISSISSIPPI VALLEY OVERNIGHT. ACTIVITY IS
EMBEDDED WITHIN A 40-50 KT DEEP LAYER MEAN FLOW FIELD ...THOUGH
GENERALLY ORIENTED PARALLEL TO IT...WHICH IS RESULTING IN A MORE
MODEST EASTWARD MOTION. BUT DAMAGING WINDS AND LARGE HAIL WILL
REMAIN A POSSIBILITY...PARTICULARLY WITH A SEGMENT LIKELY TO SURGE
THROUGH LITTLE ROCK BETWEEN 07-08Z.

BOUNDARY LAYER MOISTENING AND DESTABILIZATION APPEARS LIKELY AT
LEAST ACROSS THE REMAINDER OF NORTHEAST ARKANSAS...THE MISSOURI
BOOTHEEL AND WESTERN TENNESSEE BY 09Z. THIS SHOULD OCCUR JUST PRIOR
TO THE PASSAGE OF THE SQUALL LINE...WHICH MAY CROSS THE MISSISSIPPI
RIVER DURING THE 09-10Z...AS A SMALLER SCALE IMPULSE ...PIVOTING
AROUND THE CLOSED LOW...LIFTS ACROSS THE OZARK PLATEAU TOWARD THE
LOWER OHIO VALLEY.

DISCRETE SUPERCELL DEVELOPMENT AHEAD OF THE LINE WILL REMAIN A
POSSIBILITY. AND...LARGE CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS WILL
SUPPORT THE RISK FOR TORNADOES WITH THE DISCRETE ACTIVITY... AND
PERHAPS WITHIN THE LINE.

AREAS AFFECTED...NRN LA...SERN AR...CNTRL AND NRN MS...WRN/MIDDLE TN

CONCERNING...TORNADO WATCH 139...

VALID 150921Z - 151045Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 139 CONTINUES.

A NEW WW MAY BECOME NECESSARY EAST OF WW 139 WITHIN THE NEXT HOUR OR
TWO.

INFLOW INTO ONGOING STRONG/SEVERE MESOSCALE CONVECTIVE SYSTEM IS
STRONGEST ON IT SOUTHERN FLANK...NOW SPREADING ACROSS SOUTHERN
ARKANSAS AND NORTHERN LOUISIANA...WHERE BOUNDARY LAYER MOISTURE
CHARACTERIZED BY MID/UPPER 60S SURFACE DEW POINTS CONTINUES TO
SUPPORT MODERATE CAPE AROUND 1000-1500 J/KG. IN THE PRESENCE OF A
SHEARED AND STRONG DEEP LAYER MEAN FLOW FIELD...ON THE ORDER OF
40-50+ KT...THIS SEEMS LIKELY TO MAINTAIN THE STRENGTH OF THE
CONVECTION THROUGH AND BEYOND DAYBREAK...EVEN AS STRONGEST MID/UPPER
SUPPORT DEVELOPS NORTHEAST OF THE REGION TOWARD THE LOWER OHIO
VALLEY. AS A RESULT THE RISK FOR DAMAGING WIND GUSTS ...PERHAPS
ISOLATED TORNADOES...SHOULD CONTINUE EASTWARD ACROSS MUCH OF CENTRAL
MISSISSIPPI THROUGH THE 10-12Z TIME FRAME.

FARTHER NORTH...THE INTENSITY OF THE SQUALL LINE HAS RECENTLY
DIMINISHED AS IT APPROACHED THE MISSISSIPPI RIVER...BUT BOUNDARY
LAYER MOISTENING IN A NARROW CORRIDOR AHEAD OF THE ACTIVITY STILL
MAY PROVIDE POTENTIAL FOR INTENSIFICATION ACROSS PARTS OF WESTERN
INTO MIDDLE TENNESSEE THROUGH DAYBREAK.
