   ...THERE IS A MDT RISK OF SVR TSTMS OVER PARTS OF WRN TX...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FROM NERN NM THROUGH WRN AND S
   CNTRL TX AND THE W CNTRL FL PENINSULA...
   
   ...NERN NM THROUGH WRN AND CNTRL TX...
   
   LATE THIS AFTERNOON A QUASISTATIONARY BOUNDARY EXTENDS FROM NWRN OK
   SWWD THROUGH THE TX PANHANDLE JUST S OF AMARILLO THEN WWD INTO NRN
   NM. AN OUTFLOW BOUNDARY EXTENDS FROM NEAR JUNCTION NWWD THROUGH W TX
   WHERE IT INTERSECTS THE STATIONARY FRONT NEAR AMARILLO. THE WARM
   SECTOR HAS BECOME MODERATELY UNSTABLE WITH MLCAPE FROM 1500 TO 2000
   J/KG. THE STRONGEST INSTABILITY IS CURRENTLY INDICATED IN VICINITY
   OF THE OUTFLOW BOUNDARY ACROSS THE SRN PARTS OF W TX. LARGE SCALE
   ASCENT ACCOMPANYING ESEWD MOVING VORT MAX OVER THE SRN HIGH PLAINS
   WILL CONTINUE TO ENHANCE CONVECTIVE DEVELOPMENT IN VICINITY OF THE
   BOUNDARY ACROSS THE TX PANHANDLE. OTHER STORMS WILL CONTINUE OVER
   THE HIGHER TERRAIN OF NERN MN WITHIN UPSLOPE REGIME. FARTHER S IN
   MODERATE RISK AREA...THE ATMOSPHERE WILL CONTINUE TO DESTABILIZE AND
   OTHER STORMS ARE EXPECTED TO DEVELOP ALONG NRN EXTENTION OF OUTFLOW
   BOUNDARY OVER THE SRN TX PANHANDLE AND SPREAD SEWD DURING THE
   EVENING. SUPERCELLS WITH VERY LARGE HAIL AND ISOLATED TORNADOES WILL
   BE THE INITIAL MAIN THREATS. ACTIVITY MAY CONSOLIDATE INTO AN MCS
   LATER THIS EVENING WITH AN INCREASING THREAT OF DAMAGING WIND.
   
   
   ...FL...
   
   
   STRONG SURFACE HEATING IS OCCURRING IN THE WAKE OF MORNING MCS
   ACROSS MUCH OF CNTRL AND SRN FL WHERE RICH LOW LEVEL MOISTURE
   RESIDES. THIS IS CONTRIBUTING TO DESTABILIZATION WITH MLCAPE FROM
   AROUND 2000 J/KG ACROSS SRN FL TO AROUND 1500 J/KG OVER CNTRL
   PORTIONS. A FEW STRONG/SEVERE STORMS MAY DEVELOP OUT OF THE CLUSTER
   OF CUMULUS IN VICINITY OF BOUNDARY ACROSS SRN FL. HOWEVER...THE
   PRIMARY SEVERE THREAT IS EXPECTED LATE TONIGHT OVER W CNTRL FL WHEN
   CONVECTIVE CLUSTER OVER THE ERN GULF MAY MOVE ONSHORE...AND WIND
   FIELDS SHOULD STRENGTHEN WITH THE APPROACH OF UPPER TROUGH OVER THE
   CNTRL GULF. PRIMARY THREATS ARE EXPECTED TO BE DAMAGING WIND AND
   ISOLATED TORNADOES.
