   ...THERE IS A SLGT RISK OF SVR TSTMS FOR THE ERN DAKOTAS AND WRN
   MN....
   
   ...SYNOPSIS...
   HEIGHTS WILL GRADUALLY RISE OVER MUCH OF THE CONUS AS A MID LEVEL
   RIDGE STRENGTHENS OVER THE SRN/CENTRAL ROCKIES...AND A TROUGH OVER
   THE MS VALLEY AND GREAT LAKES FILLS AND LIFTS NEWD.  THE MAIN BELT
   OF WLYS WILL BE LOCATED FROM THE PRAIRIE PROVINCES EWD OVER THE NRN
   TIER OF STATES TO QUEBEC AND NRN NEW ENGLAND...WITHIN WHICH A LOW
   AMPLITUDE SHORTWAVE TROUGH WILL MOVE OVER SRN SASKATCHEWAN AND
   MANITOBA.  AT THE SURFACE...A WEAK TROUGH WILL ACCOMPANY THE
   DE-AMPLIFYING GREAT LAKES MID LEVEL TROUGH FROM THE OH VALLEY TO THE
   SAINT LAWRENCE VALLEY. A FEW STORMS WITH STRONG WIND GUSTS MAY
   OCCUR WITHIN THE WARM SECTOR FROM THE UPPER OH VALLEY TO INTERIOR
   NEW ENGLAND WHERE MODEST/UNIDIRECTIONAL LOW-MID LEVEL FLOW IS
   EXPECTED...BUT POOR LAPSE RATES WILL LIMIT INSTABILITY AND THE
   OVERALL SEVERE THREAT THIS AREA.  A SOMEWHAT GREATER THREAT FOR
   SEVERE STORMS IS EXPECTED ACROSS THE ERN DAKOTAS AND MN AREA DURING
   THE AFTERNOON AND INTO THE OVERNIGHT HOURS.
   
   ...ERN DAKOTAS/MN...
   BOUNDARY LAYER DEWPOINTS IN THE 60S WILL GRADUALLY SPREAD NWD ACROSS
   THE PLAINS IN RESPONSE TO LEE TROUGHING...BUT THE MARITIME TROPICAL
   AIR MASS SHOULD BE CONFINED TO THE GULF COAST AND ERN STATES. 
   HOWEVER...LOW-LEVEL MOISTURE WILL LIKELY BE ENHANCED BY
   EVAPOTRANSPIRATION FROM NEB NEWD TO MN...WHERE MID-UPPER 60
   DEWPOINTS WILL BE POSSIBLE.  THE MAIN CONCERNS FOR THIS AREA WILL BE
   STORM COVERAGE GIVEN THE TENDENCY FOR HEIGHT RISES OVER THE
   PLAINS...AND A HORIZONTAL DECOUPLING OF THE STRONGEST FORCING FOR
   ASCENT /CLOSER TO THE CANADIAN BORDER/ AND THE STRONGER INSTABILITY
   FARTHER TO THE SW.  STILL...THE COMBINATION OF INCREASING MOISTURE
   ...STEEP MID LEVEL LAPSE RATES...AND 30-50 KT WNWLY MID LEVEL FLOW
   SHOULD SUPPORT A FEW SEVERE STORMS WITH LARGE HAIL AND DAMAGING
   WINDS BY LATE AFTERNOON INTO THE OVERNIGHT HOURS.
