VALID 151613Z - 151815Z

TORNADO THREAT CONTINUES TO INCREASE.  GREATEST RISK FOR
TORNADOES...A COUPLE OF WHICH COULD BE SIGNIFICANT...WILL EXIST IN A
REGION BOUNDED BY A LITTLE ROCK AR-VICHY MO-SALEM IL-EVANSVILLE
IND-CROSSVILLE TN LINE THROUGH AT LEAST MID-AFTN.

STRONGEST PRESSURE FALLS EXIST FROM THE KSTL AREA NEWD INTO CNTRL
IL.  DEEPENING SFC LOW OVER SWRN MO WILL RAPIDLY DEVELOP NEWD TOWARD
THESE FALLS THROUGH MID-AFTN.  THE WARM/MOIST BOUNDARY LAYER ALONG
THE OH VLY WAS BEGINNING TO ADVECT N OF THE OH RVR... BUT WAS A
LITTLE SLOW TO ERODE ACROSS THE OZARKS.  AS THE LOW REDEVELOPS
NEWD...THE WARM AIR SHOULD ADVANCE INTO ECNTRL MO-CNTRL IL-CNTRL IND
LINE BY MID-AFTN.

STRONGEST LLJ AXIS IS EXPECTED TO EXIST FROM THE MS DELTA NWD INTO
WRN KY AND CNTRL IND BENEATH INCREASING SWLY FLOW OF 100+ KTS AT H5.
 RESULTANT DEEP/LOW-LEVEL SHEAR WILL BE MORE THAN SUFFICIENT FOR
SUPERCELLS/TORNADOES.  THE STRONGEST LOW-LEVEL SHEAR WILL EXIST
CLOSER TO THE TRACK OF THE SFC LOW/WARM FRONT...MAINLY FROM PARTS OF
AR INTO ECNTRL MO...CNTRL/SRN IL...SRN IND...WRN KY AND WRN TN.

PRE-FRONTAL CONFLUENCE BANDS...ALREADY DEVELOPING ACROSS CNTRL AR
AND SRN MO WILL GRADUALLY INTENSIFY WITH BOTH DISCRETE AND MIXED
LINEAR-DISCRETE MODES LIKELY TO EXIST. THE SEVERE THREAT WILL
GRADUALLY DIMINISH FROM W-E ACROSS SRN MO/AR/NERN TX AS THE COLD
FRONT BEGINS TO ACCELERATE EWD.
