   ...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF THE LOWER MS AND
   TN VALLEYS INTO THE SERN STATES...
   
   ...MS...AL...GA...TN...NWRN FL...
   
   UPPER LOW CENTERED OVER NW AR WILL CONTINUE SLOWLY EWD OVERNIGHT. A
   STRONG VORTICITY MAX/JET STREAK IS CURRENTLY ROTATING THROUGH THE
   BASE OF THIS UPPER LOW. THIS FEATURE WILL EJECT EWD THROUGH THE
   LOWER MS VALLEY AND INTO THE SWRN PARTS OF THE SERN STATES.
   DOWNSTREAM FROM THE UPPER LOW A STRONG SLY LOW LEVEL JET WILL
   PERSIST...INITIALLY FROM ERN MS...WRN AL...WRN AND MIDDLE TN THEN
   SLOWLY SHIFTING EWD THROUGH THE REMAINDER OF TN...AL AND INTO GA
   OVERNIGHT.
   
   AN OCCLUDED FRONT EXTENDS FROM A SURFACE LOW IN NRN AR SWD THROUGH
   WRN MS THEN INTO SERN LA WHERE IT BECOMES A COLD FRONT. A WARM FRONT
   EXTENDS FROM NRN AL WWD THROUGH NWRN MS WHERE IT INTERSECTS THE
   OCCLUDED BOUNDARY. PARTIALLY MODIFIED GULF AIR WITH SURFACE
   DEWPOINTS IN THE LOW 60S HAS SPREAD NWD THROUGH WARM SECTOR INTO
   CNTRL/SRN AL AND CNTRL/SRN MS. THE BEST INSTABILITY HAS BEEN
   CONFINED TO AN AXIS JUST AHEAD OF THE COLD FRONT FROM EXTREME SERN
   LA THROUGH SRN AND CNTRL MS WHERE MLCAPE RANGES FROM 800 TO 1200
   J/KG. THE STABILIZING EFFECTS OF A LARGE MCS THAT EXTENDS THROUGH
   MUCH OF AL INTO THE WRN FL PANHANDLE HAS RESULTED IN WEAKER
   INSTABILITY IN THIS REGION...WITH MUCAPE GENERALLY AOB 500 J/KG.
   
   SCATTERED STORMS ARE EXPECTED TO CONTINUE DEVELOPING WITHIN ZONE OF
   ASCENT IN WARM SECTOR ALONG LOW LEVEL JET FROM ERN MS INTO AL AND
   TN...GRADUALLY SPREADING EWD OVERNIGHT. STRONGEST STORMS...WITH
   POTENTIAL OF ISOLATED DAMAGING WIND...HAIL AND ISOLATED TORNADOES...
   ARE EXPECTED FROM ERN MS INTO PARTS OF AL AND THE FL PANHANDLE.
   STRONG FLOW AND VERTICAL SHEAR PROFILES WILL GRADUALLY SHIFT EAST
   INTO ERN TN AND GA OVERNIGHT. HOWEVER...THE STABILIZING EFFECTS OF
   THE LEAD MCS WILL LIKELY LIMIT DEGREE OF RECOVERY WITH INSTABILITY
   EXPECTED TO REMAIN VERY MARGINAL.
   
   ...NERN AR...
   
   STORMS DEVELOPING IN VICINITY OF THE OCCLUDED FRONT AND E OF SURFACE
   LOW MAY REMAIN CAPABLE OF PRODUCING ISOLATED HAIL AND POSSIBLY AN
   ISOLATED TORNADO OR TWO NEXT COUPLE HOURS. HOWEVER...THIS ACTIVITY
   IS EXPECTED TO WEAKEN AFTER 02Z AS THE BOUNDARY LAYER BEGINS TO
   STABILIZE.
