   ...LOWER MI AREA INTO THE UPPER MIDWEST...
   COMPACT VORT MAX CONTINUES TO MIGRATE NEWD ACROSS LK MI ATTM...WITH
   AN ASSOCIATED COLD FRONT ARCING FROM WRN LWR MI SWWD INTO NRN
   IL...THEN NWWD INTO THE UPPER MS VLY.  A WARM FRONT HAS MOVED NWD
   INTO THE THUMB AREA WITH WARM SECTOR CHARACTERIZED BY TEMPERATURES
   IN THE MID 70S AND SURFACE DEW POINTS IN THE LOWER 60S.  TSTMS
   SHOULD CONTINUE TO ADVANCE ENEWD ACROSS THE CNTRL/SRN PORTIONS OF
   LOWER MI THE NEXT SEVERAL HOURS.  VERTICAL SHEAR PROFILES ARE
   MARGINALLY SUPPORTIVE OF SUPERCELLS...WITH MAINLY SHORT LINES OF
   TSTMS EXPECTED.  DAMAGING WINDS AND LARGE HAIL WILL BE THE PRIMARY
   THREATS...THOUGH A BRIEF ISOLD TORNADO MIGHT OCCUR WHERE LOW LEVEL
   FLOW IS BACKED INVOF WARM FRONT ACROSS ECNTRL LOWER MI.  
   
   ...UPPER MS VLY...
   VAPOR IMAGERY SEEMS TO INDICATE A WEAK MIDLEVEL SPEED MAX MOVING
   ACROSS NCNTRL SD...WITH EXIT REGION SPREADING SEWD ACROSS NRN/CNTRL
   MN AND WRN WI.  SURFACE ANALYSIS DEPICTS TAIL END OF A BOUNDARY
   EXTENDING NW FROM NEAR CHICAGO NWWD INTO THE UPPER MS VLY.  TSTMS
   HAVE BEEN INTENSIFYING INVOF THIS BOUNDARY...BENEATH RELATIVELY
   COOL CYCLONIC FLOW ALOFT.  A FEW OF THE STRONGER STORMS MAY PRODUCE
   SEVERE HAILSTONES AND PERHAPS AN ISOLD DAMAGING WIND GUST.  
   
   ...PLAINS AREA...
   SEVERAL AREAS OF POTENTIAL CONVECTIVE INITIATION  ACROSS THE
   PLAINS.  HIGHER PROBABILITY OF SEVERE SHOULD EVOLVE LATER THIS
   EVENING ACROSS NRN PARTS OF THE SLGT AREA.  BOUNDARY LAYER FLOW HAS
   TURNED UPSLOPE WITH 50S DEW POINTS ADVECTING WWD.  CU HAS BEEN
   INCREASING ACROSS THE HIGHER TERRAIN OF CO/WY...DOWNSTREAM FROM
   APPROACHING MIDLEVEL IMPULSE OVER MT.  TSTMS SHOULD INITIATE BY
   LATE THIS AFTERNOON AND MOVE OFF THE TERRAIN INTO THE UNSTABLE
   LOWER PLAINS THIS EVENING.  DEEP LAYER SHEAR WILL BE FAVORABLE FOR
   SUPERCELLS WITH LARGE HAIL.  OVERNIGHT...STRONGEST UPSLOPE/MOIST
   INFLOW SHOULD EXIST FOR A POSSIBLE LONGER LIVED MCS FROM SERN
   WY/SWRN NEB INTO WRN/NRN KS OVERNIGHT WITH HAIL AND DAMAGING WIND
   THREATS.
   
   ANOTHER AREA OF INITIATION WILL PROBABLY TAKE PLACE WITHIN HIGHER
   INSTABILITY AXIS ACROSS ERN CO...WRN KS SWD INTO THE SRN HIGH
   PLAINS.  IN ADDITION TO THE HIGHER TERRAIN TSTMS POSSIBLY
   MIGRATING/DEVELOPING EWD ONTO THE ADJACENT PLAINS...OUTFLOW
   BOUNDARY CONTINUES TO BE WELL-DEFINED OVER SWRN KS AND NWRN OK AND
   COULD BE A FOCUS FOR ADDITIONAL TSTMS GIVEN THAT CONVECTIVE
   TEMPERATURES NEAR 90F HAVE LARGELY BEEN EXCEEDED.  MAGNITUDE OF
   INSTABILITY WILL LIKELY OFFSET WEAK VERTICAL SHEAR TO SUPPORT LARGE
   HAIL AND DAMAGING WINDS WITH ANY STORMS THAT DO FORM.  
   
   ...COASTAL SERN STATES...
   TAIL END OF A WEAK MIDLEVEL IMPULSE EVIDENT IN VAPOR IMAGERY IS
   MOVING ACROSS UPSTATE SC ATTM AND SEEMS TO BE AIDING IN STRONGER
   TSTMS FROM SC NEWD INTO COASTAL NC.  LATEST RUC SOUNDINGS SUGGEST
   SLIGHTLY ACCELERATED MIDLEVEL FLOW ASSOCIATED WITH THE
   DISTURBANCE...AND IS SUPPORTING SOME ORGANIZATION OF THE TSTMS. 
   ISOLD DAMAGING WIND GUSTS AND HAIL WILL LIKELY OCCUR WITH THE
   STRONGER STORMS.  REFER TO MCD1534 FOR MORE DETAILS.
