   ...TORNADO OUTBREAK IS POSSIBLE TODAY ACROSS PORTIONS OF ERN KS...
   SERN NEB AND NWRN MO THIS AFTERNOON AND EVENING...
   
   ...SYNOPSIS...
   STRONG SHORTWAVE TROUGH AND 80 KT MID LEVEL JET MAX WILL MOVE
   RAPIDLY NEWD FROM NM INTO KS THIS AFTERNOON. SURFACE LOW ASSOCIATED
   WITH THIS SYSTEM IS FORECAST TO DEEPEN AND EJECT NEWD FROM ERN CO
   INTO N CENTRAL KS BY LATE AFTERNOON. WARM FRONT FROM CENTRAL KS EWD
   INTO EXTREME SRN MO IS MOVING NWD AND EXTEND EWD FROM THE SURFACE
   LOW NEAR THE KS/NEB BORDER EWD INTO SRN IL...WHILE THE DRYLINE IS
   EXPECTED TO EXTEND SWD ACROSS CENTRAL KS/OK/TX. 
   
   ...CENTRAL PLAINS EWD INTO THE MID MS / LOWER OH VALLEY...
   DRIER MID LEVEL AIR/CLEARING IS SPREADING NEWD ACROSS NWRN OK/WRN
   KS AND WILL OVERSPREAD MUCH OF THE MODERATE AND HIGH RISK AREAS BY
   LATE AFTERNOON. TEMPERATURES WARMING INTO THE 80S...STEEP LAPSE
   RATES AND DEWPOINTS IN THE LOWER 70S WILL RESULT IN MLCAPE VALUES 
   APPROACHING 3500 J/KG IN THE WARM SECTOR. STRONGEST FORCING WILL
   SPREAD INTO KS THIS AFTERNOON AND THIS SHOULD BE SUFFICIENT FOR
   CAPPING INVERSION TO BE LIFTED...WITH STORMS DEVELOPING EAST OF THE
   DRYLINE AND ALONG/SOUTH OF WARM FRONT BY MID AFTERNOON. ONCE STORMS
   DEVELOP...THEY WILL BE LOCATED WITHIN A STRONGLY SHEARED
   ENVIRONMENT WITH DEEP LAYER SHEAR AROUND 70 KT. STORMS SHOULD
   RAPIDLY EVOLVE INTO SUPERCELLS. THE STRENGTH OF THE INSTABILITY AND
   SHEAR INDICATES THAT VERY LARGE HAIL AND DAMAGING WINDS WILL OCCUR
   WITH THESE STORMS. ALSO...STRONG LOW LEVEL SHEAR...ESPECIALLY EAST
   OF THE SURFACE LOW WILL RESULT IN BACKED BOUNDARY WINDS...
   SUGGESTING TORNADOES ARE ALSO LIKELY. SOME MAY BE QUITE STRONG
   GIVEN THE STRENGTH OF THE ENVIRONMENTAL SHEAR. 
   
   THE STORMS ARE EXPECTED TO SHIFT NEWD OVERNIGHT ACROSS AN
   INCREASINGLY STABLE ENVIRONMENT. HOWEVER...THE STRENGTH OF THE
   UPPER LEVEL FORCING AND INSTABILITY SHOULD BE SUFFICIENT TO
   MAINTAIN A THREAT OF SEVERE HAIL AND WIND DAMAGE THROUGH THE
   OVERNIGHT HOURS.     
   
   ...S CENTRAL KS SWD INTO TX...
   12Z OUN SOUNDING SHOWED THE BOUNDARY LAYER MOISTURE TO EAST OF THE
   DRYLINE WAS FAIRLY DEEP...UP TO 800 MB. DESPITE THE WARMING THAT
   WILL OCCUR ALOFT...SURFACE TEMPERATURES WARMING TO NEAR 90 DEGREES
   WITH LOWER 70 DEWPOINTS WILL RESULT IN MLCAPES NEAR 4000 J/KG. A
   FEW THUNDERSTORMS SHOULD DEVELOP EAST OF THE DRYLINE AROUND 21Z AS
   SRN TAIL OF KS SHORTWAVE TROUGH BRUSHES THE AREA. THE STRONG
   INSTABILITY PLUS 50 TO 70 KT DEEP LAYER SHEAR WILL BE FAVORABLE FOR
   SUPERCELLS. ALTHOUGH SHEAR WILL BE SOMEWHAT LESS FAVORABLE FOR
   TORNADOES THAN ACROSS THE MODERATE/HIGH RISK AREAS...STORMS THAT
   DEVIATE FROM THE MEAN FLOW WOULD BE CAPABLE OF PRODUCING TORNADOES.
   HOWEVER...THE MAIN THREAT WILL BE VERY LARGE HAIL AND DAMAGING
   WINDS.
   
   ...TN AND OH VALLEYS...
   COMPLEX OF STRONG/SEVERE STORMS CONTINUE TO TRACK EWD THROUGH NERN
   AR AND SHOULD MOVE MORE ENEWD AS IT ENCOUNTERS DEEPER SWLY FLOW
   ALOFT. MLCAPES WILL BE FROM 1500-2000 J/KG AND DEEP LAYER SHEAR
   SHOULD BE 40-50 KT WITH A THREAT OF SUPERCELLS AND A FEW
   TORNADOES...LARGE HAIL AND STRONG WIND GUSTS.
   
   ...VA AREA...
   WEAK COLD FRONT STRETCHES ACROSS NRN VA THIS MORNING AND SHOULD
   MOVE LITTLE THROUGH THE DAY. STORMS SHOULD INTENSIFY NEAR THIS
   BOUNDARY AS LIFTING IS AIDED BY A MID LEVEL SPEED MAX MOVING IN
   FROM WV. DEEP LAYER SHEAR IS FAVORABLE FOR STORMS WITH MID LEVEL
   ROTATION...WITH SEVERE HAIL AND SOME WIND DAMAGE LIKELY.
