   ...MID MS VALLEY/OH VALLEY/TN VALLEY/OZARK REGION/CNTRL APP MTNS...
   
   MAJOR SEVERE WEATHER AND TORNADO OUTBREAK IS BEGINNING ACROSS THE
   MS VALLEY AND WILL CONTINUE INTO THE OH-TN VALLEYS OVERNIGHT. THE
   CENTER OF INSTABILITY WAS CURRENTLY OVER WCNTRL MO WITH A BAND OF
   SBCAPE OF 3000 TO 5000 J/KG ACROSS WRN MO. A STRONG NEGATIVELY
   TILTED UPPER-TROUGH WAS CURRENTLY MOVING EWD ACROSS KS WITH A SHARP
   WELL-DEFINED LOW TO MID-LEVEL JET ROUNDING THE BASE OF THE TROUGH
   ACROSS SW MO. STRONG LARGE-SCALE FORCING WILL APPROACH THE
   CONVECTIVE LINE ONGOING ACROSS ERN OK/WRN MO AND STORMS WILL
   RAPIDLY INTENSIFY LATE THIS AFTERNOON. 0-6 KM SHEAR OF 60-70 KT WAS
   PRESENT ACROSS THE REGION WITH STRONG DIRECTIONAL SHEAR WITH
   HEIGHT. FORECAST SOUNDINGS ACROSS MO/IL/AR/SERN IA/IN SHOWED LARGE
   HODOGRAPHS FAVORABLE FOR TORNADIC SUPERCELLS. AS A RESULT...
   DISCRETE SUPERCELL STORMS WILL BE FAVORED AS A BROKEN LINE DEVELOPS
   AND MOVES ACROSS THE MID-UPPER MS VALLEY LATE THIS AFTERNOON INTO
   THE EVENING. WIDESPREAD TORNADOES WITH SOME STRONG TORNADOES APPEAR
   LIKELY ESPECIALLY ACROSS MO/IL AS THE MID-LEVEL JET PUNCHES INTO
   THE REGION THIS EVENING. THE LOW-LEVEL JET AND UPPER-LEVEL JET ARE
   MOST LIKELY TO PHASE OVER ERN MO/WRN IL WITH SR HELICITIES RANGING
   FROM 300 TO 400 M2/S2. THE STRONG LARGE SCALE FORCING...LARGE
   AMOUNT OF INSTABILITY AND IMPRESSIVE HODOGRAPHS SUGGEST A VIOLENT
   TORNADO WILL ALSO BE POSSIBLE ESPECIALLY ACROSS ERN MO OR WRN IL.
   
   LARGE HAIL/DAMAGING WINDS WILL ALSO BE LIKELY AS A DERECHO DEVELOPS
   OVERNIGHT ACROSS THE OH/TN VALLEYS. WIDESPREAD WIND DAMAGE IS
   LIKELY ALONG AND JUST AHEAD OF THE LINE AS IT PROGRESSES EWD INTO
   IN/OH/KY/WV AFTER MIDNIGHT. SEVERE WEATHER THREAT SHOULD CONTINUE
   THROUGH DAYBREAK AS THE SQUALL-LINE CONTINUES INTO THE CNTRL
   APPALACHIAN MOUNTAINS. 
   
   ...VA/NC...
   A WARM FRONT EXTENDING EWD ACROSS KY/WV/VA WILL CONTINUE TO LIFT
   NWD AS NUMEROUS CONVECTION WORKS EWD ALONG AND N OF THE BOUNDARY.
   SBCAPE WAS 2000 TO 3000 J/KG ALONG AND S OF THE BOUNDARY WITH
   WEAKER INSTABILITY TO THE N. DEEP LAYER SHEAR WAS STRONG WITH 50 TO
   60 KT ACROSS THE REGION AND SUPERCELLS WILL BE LIKELY ESPECIALLY
   NEAR THE WARM FRONT WHERE THEY WILL HAVE ACCESS TO THE VERY
   UNSTABLE AIR. LARGE HAIL/DAMAGING WINDS WILL BE LIKELY WITH
   SUPERCELLS. ISOLATED TORNADOES WILL ALSO BE POSSIBLE ESPECIALLY
   WITH STORMS THAT RIDE EWD ALONG THE BOUNDARY.
