   ...WIDESPREAD DAMAGING WIND EVENT IS POSSIBLE ACROSS PORTIONS OF
   THE MID/UPPER MS AND OH VALLEYS SUNDAY AFTERNOON TO SUNDAY NIGHT...
   
   ...SYNOPSIS...
   UPPER HIGH WILL RETROGRADE WWD ACROSS THE WRN STATES AS A STRONG
   SHORT WAVE TROUGH DROPS SEWD INTO THE UPPER MIDWEST.  BAND OF 50-60
   KT MID-LEVEL NWLY FLOW WILL MOVE SWD ON SUNDAY AND EXTEND FROM THE
   DAKOTAS TO THE MID MS/OH VALLEYS BY 12Z MONDAY.  SEVERAL SHORT WAVE
   TROUGHS EMBEDDED WITHIN THIS NWLY FLOW WILL AID IN EPISODES OF
   SEVERE STORMS DURING THE DAY 2 PERIOD ACROSS THE MID/UPPER MS TO OH
   VALLEYS.
   
   ...MID/UPPER MS VALLEY TO OH VALLEY...
   COLD FRONT EXTENDING FROM MN SWWD INTO SD AT THE BEGINNING OF THE
   PERIOD WILL MOVE SEWD ON SUNDAY...REACHING THE SRN GREAT LAKES SWWD
   TO THE CENTRAL PLAINS BY 12Z MONDAY.  AN OUTFLOW BOUNDARY EXPECTED
   FROM EARLY SUNDAY MORNING CLUSTER OF STORMS ACROSS WI...AND A WARM
   FRONT ARE PROGGED TO EXTEND FROM THE UPPER MS VALLEY ESEWD TO SRN
   MI/OH VALLEY.  A DEEP...MOIST BOUNDARY LAYER ALONG/S OF WARM FRONT
   COMBINED WITH STEEP LAPSE RATES WILL RESULT IN A VERY UNSTABLE AIR
   MASS BY AFTERNOON.  
   
   AS LARGE SCALE ASCENT INCREASES ACROSS THE MID/UPPER MS TO OH
   VALLEYS WITH THE UPPER TROUGH DROPPING SEWD...WIND FIELDS WILL
   INCREASE IN STRENGTH THROUGH THE DAY.  MODELS SUGGEST AN MCS SHOULD
   BE ONGOING AT THE BEGINNING OF THE PERIOD ACROSS WI ASSOCIATED WITH
   A LEAD SHORT WAVE TROUGH OVER THE WRN GREAT LAKES AND WAA WITH A
   WLY 30 KT LLJ OVER NRN IA INTO NRN IL.  THIS ACTIVITY WILL SPREAD
   EWD ACROSS MI THROUGH THE DAY REACHING WRN PA/SWRN NY BY SUNDAY
   EVENING.  STORMS WILL ALSO DEVELOP ACROSS THE MID/UPPER MS VALLEY
   BY EARLY AFTERNOON AND INCREASE IN INTENSITY AS THEY SPREAD SEWD
   WITHIN THE VERY UNSTABLE AIR MASS AND STRONG DEEP LAYER SHEAR. 
   LOW-LEVEL VEERING PROFILES SUGGEST A TORNADO THREAT WILL BE
   POSSIBLE WITH INITIAL STORMS OVER SRN MN/IA WITH THE CONVECTIVE
   MODE EVOLVING INTO A THREAT FOR SIGNIFICANT DAMAGING WINDS AS
   STRONG DEEP WLY WINDS DEVELOP ACROSS IND INTO WRN OH BY SUNDAY
   NIGHT.
   
   ...SRN MO/AR/ERN KS/ERN OK...
   A WEAK SURFACE LOW IS PROGGED TO BE OVER SRN KS SUNDAY WITH A
   SURFACE TROUGH EXTENDING SEWD THROUGH ERN OK.  MUCH OF THIS REGION
   SHOULD REMAIN CAPPED THROUGH THE DAY.  HOWEVER...A WEAK UPPER SHORT
   WAVE TROUGH TRACKING SEWD INTO KS SUNDAY EVENING COMBINED WITH
   INCREASING WAA WITH A STRENGTHENING WLY LLJ OVER NRN OK SHOULD
   ALLOW ELEVATED STORMS TO DEVELOP ALONG/E OF THE SURFACE TROUGH
   SUNDAY EVENING AND CONTINUE OVERNIGHT.  STEEP LAPSE RATES AND
   MODERATE ELEVATED INSTABILITY WILL SUPPORT MAINLY A HAIL THREAT.
