   ...THERE IS A SLGT RISK OF SVR TSTMS FROM ERN KS TO THE TX
   PANHANDLE...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF WI AND NRN
   IL...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FROM SERN IL TO OH...
   
   ...CENTRAL/SRN PLAINS...
   
   HIGH PLAINS MCS HAS EVOLVED OVER SERN CO/SWRN KS.  THIS ACTIVITY
   CONTINUES TO MATURE AS IT PROPAGATES EWD ALONG/NORTH OF EXISTING SFC
   BOUNDARY DRAPED FROM SOUTH OF MHK TO NEAR DDC IN KS.  IN
   ADDITION...REGIONAL RADAR DATA SUGGESTS A MVC MAY BE DEVELOPING IN
   THE WAKE OF THE STRONGEST BOW-SHAPED CONVECTION OVER SWRN KS.  WITH
   AN EXPANDING PRECIPITATION SHIELD IT APPEARS THIS MCS SHOULD
   CONTINUE ITS EWD MOVEMENT ALONG FRONTAL ZONE...ESPECIALLY GIVEN THE
   ELY COMPONENT TO BOUNDARY LAYER AND SLY LLJ THAT SHOULD INCREASE
   OVER THE NEXT FEW HOURS.  DAMAGING WINDS WILL OCCUR AHEAD OF BOW
   SHAPED FEATURE...OTHERWISE HAIL MAY BECOME THE PRIMARY CONCERN WITH
   MUCH OF THE PLAINS ACTIVITY.
   
   A SIGNIFICANT AMOUNT OF CONVECTION HAS DEVELOPED OVER ERN NM/WRN TX
   PANHANDLE.  THIS ACTIVITY SHOULD CONTINUE EWD INTO THE TX SOUTH
   PLAINS OVER THE NEXT SEVERAL HOURS WITH A GRADUAL UPWARD TREND IN
   AREAL COVERAGE AND INTENSITY...ESPECIALLY GIVEN THE AXIS OF
   INSTABILITY THAT EXISTS DOWNSTREAM...ROUGHLY 2500 J/KG SBCAPE. 
   LARGE HAIL SHOULD BE THE PRIMARY SEVERE THREAT.
   
   ...WI/OH VALLEY...
   
   LONG-LIVED MCS STRUCTURE CONTINUES ITS ENEWD MOVEMENT ACROSS SRN
   MN/NERN IA INTO WI.  THIS COMPLEX OF STORMS CONTINUES TO DEVELOP
   NEWD-EXTENDING WARM ADVECTION BANDS WELL AHEAD OF MAIN CLUSTER. 
   MUCH OF THIS ACTIVITY IS NON SEVERE AND MAY REMAIN MOSTLY BELOW
   SEVERE LEVELS...ESPECIALLY GIVEN THE PAST HISTORY. 
   HOWEVER...DESPITE THE CURRENT MODE OF THE CONVECTION...00Z PROFILES
   FROM GRB AND DVN SUGGEST SUFFICIENT DEEP LAYER VERTICAL SHEAR AND
   INSTABILITY FOR ORGANIZED UPDRAFTS CAPABLE OF PRODUCING LARGE HAIL
   OR PERHAPS SOME GUSTY WINDS.
   
   FARTHER SOUTHEAST ACROSS THE OH VALLEY...SUSTAINED WARM ADVECTION
   REGIME CONTINUES TO SPREAD NWD ACROSS THE OH VALLEY.  NUMEROUS
   DEEPENING SHOWERS AND ISOLATED THUNDERSTORMS HAVE RECENTLY DEVELOPED
   OVER SERN IL/IND.  00Z ILN SOUNDING...ALTHOUGH QUITE VEERED THROUGH
   A DEEP LAYER...SUPPORTS STORM ROTATION WITH DEEP LAYER SHEAR ON THE
   ORDER OF 35KT. GIVEN THE TROPICAL MOISTURE IN PLACE...SFC DEW
   POINTS IN THE LOWER 70S...AND PRECIPITABLE WATER VALUES ROUGHLY 1.75
   INCHES...ISOLATED TORNADOES MAY OCCUR IF SUPERCELL STRUCTURES CAN
   EVOLVE WITHIN THIS EXPANDING THUNDERSTORM CLUSTER.

   ...NOTICE...
   FOR USERS DECODING THE POINTS PARAGRAPH HEREIN...LATITUDE AND
   LONGITUDE POINTS FOR THE CATEGORICAL AND PROBABILISTIC OUTLOOK
   GRAPHICS ALSO ARE LOCATED IN A SEPARATE PRODUCT UNDER THE WMO
   HEADINGS WUUS01 PTSDY1...WUUS02 PTSDY2...AND WUUS03 PTSDY3.  THE
   INCLUSION OF POINTS IN THIS PRODUCT WILL EVENTUALLY BE DISCONTINUED.
