   ...UPPER MS VALLEY REGION TO CENTRAL/NRN HIGH PLAINS...
   AS THE UPPER HIGH CONTINUES TO RETROGRADE WWD ACROSS THE WRN STATES
   NWLY FLOW WILL PERSIST FROM THE NRN PLAINS INTO THE GREAT LAKES. 
   MID-UPPER LEVEL FLOW WILL CONTINUE TO INCREASE ACROSS THE DAKOTAS 
   TO THE UPPER MS VALLEY/WRN GREAT LAKES AS A SPEED MAX/SHORT WAVE
   TROUGH MOVES ACROSS THIS REGION.  THIS WILL INCREASE DEEP LAYER
   SHEAR FOR ORGANIZED STORMS WITH SUPERCELLS POSSIBLE AS WELL.  
   
   EARLY AFTERNOON SURFACE ANALYSIS PLACES A SURFACE TROUGH FROM WRN
   ONTARIO SWWD ACROSS NWRN MN AND THEN WWD TO ALONG THE ND/SD
   BORDER....WHILE A SECOND FRONT WAS LOCATED FROM ERN SASKATCHEWAN TO
   ERN/SRN MT.  AIR MASS HAS BECOME VERY UNSTABLE ALONG THE MN/DAKOTAS
   SURFACE TROUGH...WITH REGIONAL RADARS SUGGESTING A STORM OVER NWRN
   MN HAS BECOME SURFACE BASED.  AS THE SHORT WAVE TROUGH MOVES TOWARD
   THE UPPER MS VALLEY THIS EVENING...THUNDERSTORMS ARE EXPECTED TO
   INCREASE IN COVERAGE ACROSS CENTRAL/NRN PORTIONS OF MN WITH A
   THREAT FOR LARGE HAIL/DAMAGING WINDS.  A FORWARD PROPAGATING MCS IS
   EXPECTED TO DEVELOP OVERNIGHT AS WLY LLJ STRENGTHENS ACROSS SRN MN
   INTO CENTRAL WI...WITH DAMAGING WINDS BEING THE PRIMARY THREAT
   OVERNIGHT.
   
   ADDITIONAL STORMS WILL CONTINUE TO DEVELOP THIS AFTERNOON/EVENING
   ACROSS THE NRN/CENTRAL HIGH PLAINS...WITHIN A MODERATELY UNSTABLE
   AIR MASS.  THIS ACTIVITY IS EXPECTED TO SPREAD EWD ACROSS THE
   DAKOTAS OVERNIGHT AS THE COLD FRONT OVER MT/SRN CANADA MOVES EWD...
   AND EXTENDS FROM NWRN MN SWWD TO SRN SD BY 12Z SUNDAY.  MODERATE
   INSTABILITY AND SUFFICIENT DEEP LAYER SHEAR SUGGEST STORMS SHOULD
   REMAIN SEVERE OVERNIGHT.
   
   ...SRN VA/CAROLINAS TO SRN GULF COAST STATES/LOWER MS VALLEY...
   A WEAK SURFACE BOUNDARY EXTENDING FROM SERN VA SWWD INTO WRN NC...
   WITH A SECOND WEAK SURFACE BOUNDARY EXTENDING FROM CENTRAL SC WSWWD
   THROUGH THE GULF COAST STATES TO SRN LA WILL CONTINUE TO BE THE
   FOCI FOR THUNDERSTORMS INTO THE EARLY EVENING.  AIR MASS ALONG/S OF
   THESE BOUNDARIES WILL REMAIN MODERATELY UNSTABLE TO SUSTAIN
   UPDRAFTS.  THE GREATEST POTENTIAL FOR THE CONTINUATION OF ORGANIZED
   STORMS WILL BE OVER SRN VA SWD TO ERN GA/FAR NRN FL AND ACROSS THE
   LOWER MS VALLEY WHERE UPPER LEVEL FLOW IS STRONGER.
   
   ...SERN KS/SWRN MO SWD TO ARKLATEX REGION...
   SURFACE ANALYSIS SHOWS THE OUTFLOW BOUNDARY FROM THE EARLIER MCS
   OVER AR EXTENDS FROM CENTRAL LA NWWD THROUGH EXTREME NERN TX/ERN OK
   TO SERN KS.  WEAK WLY LOW-LEVEL WINDS ACROSS THIS REGION WILL
   CONTINUE TO SUPPORT CONVECTIVE DEVELOPMENT ALONG/E OF THIS OUTFLOW
   BOUNDARY INTO THE EARLY EVENING.  GIVEN MODERATE INSTABILITY AND
   MODEST DEEP LAYER SHEAR /25-30 KT IN THE LOWEST 6 KM/...ISOLATED
   SEVERE STORMS ARE POSSIBLE AS ACTIVITY MOVES SSEWD.  AN INCREASE IN
   THUNDERSTORM COVERAGE/INTENSITY IS EXPECTED TOWARD 06Z ACROSS ERN
   OK/WRN AR...AS A 25 KT WLY LLJ DEVELOPS OVER ERN OK.  STEEP LAPSE
   RATES AND MODERATE ELEVATED INSTABILITY SUGGEST MAINLY A HAIL
   THREAT AS STORMS MOVE SWD OVERNIGHT INTO ERN TX/NWRN LA.  
   
   ...NV...
   CYCLONIC VORTICITY ADVECTION SPREADING NWD ACROSS NV WITH THE
   REMNANTS OF CLAUDETTE...CURRENTLY LOCATED OVER EAST CENTRAL CA/
   SWRN NV...IS EXPECTED TO AID IN CONVECTIVE DEVELOPMENT BY/AFTER
   PEAK HEATING.  MID-UPPER LEVEL MOISTURE PLUME COMBINED WITH DRY...
   DEEP MIXED BOUNDARY LAYER WILL ENHANCE THE THREAT FOR ISOLATED
   STRONG WIND GUSTS.  DRY AIR INTRUSION MOVING NWD ACROSS SRN NV
   ATTM...PER WV IMAGERY...MAY ENHANCE THE DOWNDRAFT POTENTIAL.
