THE SEVERE WEATHER THREAT FOR TORNADO WATCH 132 CONTINUES.

PRIMARY SEVERE THREAT APPEARS TO BE WITH STORMS MOVING EWD TOWARD
WRN TN AND NWRN MS NEXT COUPLE HOURS.

A QUASISTATIONARY FRONT REMAINS FROM NRN KY SWWD TO A WEAK LOW IN
EXTREME ERN AR. THIS BOUNDARY THEN EXTENDS SWWD THROUGH SRN AR AND
TO A SURFACE LOW IN NWRN LA. DESPITE WEAK INSTABILITY...STORMS HAVE
INTENSIFIED ALONG PORTION OF THE BOUNDARY OVER EXTREME ERN AR WHERE
LATEST SURFACE ANALYSIS INDICATES PRESENCE OF A WEAK MESO-LOW AND
MODEST PRESSURE FALLS. THE CONFIGURATION OF THE RADAR WITH
INFLECTION POINT NW OF MEMPHIS ALSO IMPLIES PRESENCE OF A DEEPER
CIRCULATION. THIS REGION EXISTS ALONG NOSE OF 70 KT LOW LEVEL JET
THAT IS PROVIDING STRONG STORM RELATIVE INFLOW AND CONVERGENCE.
DAMAGING WIND WILL PROBABLY REMAIN THE PRIMARY THREAT WITH THIS
ACTIVITY. HOWEVER...VERY LARGE LOW LEVEL HODOGRAPHS WILL CONTINUE TO
SUPPORT THE POTENTIAL FOR EMBEDDED SUPERCELLS WITH ISOLATED
TORNADOES.
