Convective Outlook,For May 30 -2013

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE ERN PLAINS FROM THE

   DAKOTAS TO THE RED RIVER OF OK/TX...EWD INTO SRN WI/IL...

   ...SYNOPSIS...

   LARGE SCALE UPPER TROUGH IS EXPECTED TO SHIFT INTO THE MID SECTIONS
   OF THE CONUS DURING THE DAY2 PERIOD WITH CENTER OF UPPER LOW
   FORECAST TO SETTLE INTO THE WRN DAKOTAS.  SEVERAL SPEED MAXIMA AND
   ASSOCIATED SHORT-WAVES WILL ROTATE AROUND THIS FEATURE ACROSS THE
   CNTRL ROCKIES INTO THE UPPER GREAT LAKES.  EPISODIC BOUTS OF
   STRONG/SEVERE CONVECTION SHOULD EVOLVE WITH THESE
   FEATURES...MODULATED BY DIURNAL HEATING.
