...NO SVR TSTM AREAS FORECAST...

...LWR MS/TN VLYS...
GPS PWAT/SURFACE ANALYSES SHOW A NARROW RIBBON OF MOISTURE
CONTINUING TO ADVECT NWD THROUGH LA INTO THE MID-MS VLY WITH NEAR
60F SURFACE DEW POINTS INTO CNTRL LA AND NEAR 50F AS FAR N AS NWRN
MS/ECNTRL AR.  LARGE SCALE ASCENT ASSOCIATED WITH A MID-LEVEL
SHORTWAVE TROUGH FROM IA-ERN OK WAS BEGINNING TO SPREAD ATOP THIS
MOIST AXIS AND THE COLUMN HAS MOISTENED SUFFICIENTLY FOR ELEVATED
TSTM INITIATION OVER THE MO BOOTHEEL AT EARLY AFTN.

STRONGEST LARGE SCALE HEIGHT FALLS/ASCENT ARE EXPECTED TO TRANSLATE
ENEWD THROUGH THE TN/OH VLYS OVERNIGHT.  THOUGH THE AIR MASS WILL
CONTINUE TO MODIFY FROM THE LWR MS VLY INTO THE TN VLY AHEAD OF THE
COLD FRONT...LATEST RUC SOUNDINGS SUGGEST SURFACE BASED PARCELS WILL
LIKELY REMAIN CAPPED.  MOST LIKELY SCENARIO WILL BE FOR BANDS OF
ELEVATED TSTMS TO DEVELOP ALONG/E OF THE MS /POSSIBLY S FROM ONGOING
ACTIVITY/ AND MOVE ENEWD ACROSS NRN/CNTRL MS/AL AND TN OVERNIGHT. 
EFFECTIVE SHEAR OF 40+ KTS AND WEAK MUCAPE MAY BE SUFFICIENT FOR A
STRONG STORM OR TWO WITH HAIL. IF A TSTM CAN FORM ALONG THE FRONT
FARTHER SW ACROSS CNTRL MS/LA THIS EVENING...ISOLD DAMAGING WINDS
MAY OCCUR AS UPDRAFTS THIS FAR S COULD BE ROOTED CLOSER TO THE
SURFACE.
