MESOSCALE DISCUSSION 1133
   NWS STORM PREDICTION CENTER NORMAN OK
   0202 AM CDT WED JUN 08 2011
   
   AREAS AFFECTED...MUCH OF CNTRL AND WRN WI...EXTREME NERN IA AND SERN
   MN
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 080702Z - 080930Z
   
   STORMS ARE EXPECTED TO INCREASE IN COVERAGE OVERNIGHT MAINLY ACROSS
   WI...BUT THERE IS UNCERTAINTY IF A WATCH WOULD BE NEEDED.
   
   RADAR AND IR IMAGERY...AS WELL AS GPS PW SENSORS...SHOW ZONE OF
   MOISTURE CONVERGENCE FROM ERN IA INTO W CNTRL WI WHERE A LONE CELL
   HAS DEVELOPED. THETA-E JUST OFF THE SURFACE SHOULD CONTINUE TO
   INCREASE GRADUALLY OVER THE MCD AREA WITH A PERSISTENT SWLY 40 KT
   LOW LEVEL JET.
   
   MEANWHILE...WIND FIELDS ALOFT WILL BE ON THE INCREASE AS A SHORTWAVE
   TROUGH MOVES BY TO THE N. WITH LITTLE VEERING WITH HEIGHT...WIND
   PROFILES MAY NOT BE QUITE FAVORABLE ENOUGH FOR SUPERCELLS.
   BUT...GIVEN MODERATE STEERING CURRENTS...SOME STORMS COULD MOVE FAST
   AND PERHAPS RESULT IN GUSTY WINDS.
   
   VERY WEAK CONFLUENCE IN THE LOW LEVELS MAY HELP TO ORGANIZE A ZONE
   OF STORMS...BUT OVERALL FORCING IS WEAK. THIS MAY NOT MATTER
   MUCH...WITH AMPLE MOISTURE AND NO CAPPING FOR ELEVATED PARCELS.
