   * PRIMARY THREATS INCLUDE...
     WIDESPREAD DAMAGING WINDS LIKELY WITH ISOLATED SIGNIFICANT GUSTS
       TO 80 MPH POSSIBLE
     SCATTERED LARGE HAIL LIKELY WITH ISOLATED VERY LARGE HAIL EVENTS
       TO 3 INCHES IN DIAMETER POSSIBLE
     A TORNADO OR TWO POSSIBLE

   REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
   FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH

   AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 32...WW 33...WW 34...

   DISCUSSION...ELEVATED TSTMS NOW OVER NE OK/S CNTRL KS FORMED IN
   ASSOCIATION WITH LOW-AMPLITUDE...NE-MOVING UPR IMPULSE. THE STORMS
   SHOULD CONTINUE TO STRENGTHEN AND BECOME MORE NEARLY SFC-BASED AS
   THE UPR FEATURE CONTINUES NEWD AND STORM COLD POOLS ENLARGE/MERGE.
   19Z SGF SOUNDING APPEARS TO HAVE WELL-SAMPLED THE DOWNSTREAM
   ENVIRONMENT...WHERE ADDITIONAL SFC HEATING WILL FURTHER ENHANCE
   LOW-LVL BUOYANCY. 40 KT WSWLY DEEP SHEAR WILL SUPPORT SUSTAINED
   STORMS/SUPERCELLS. VEERED LOW-LVL WINDS AND EXPECTED FAIRLY
   SUBSTANTIAL STORM OUTFLOW SUGGEST THAT BROKEN LINES/CLUSTERS WITH
   EMBEDDED SUPERCELLS WILL BE THE PREDOMINANT STORM MODE...WITH AN
   ATTENDANT THREAT FOR HIGH WIND...VERY LARGE HAIL...AND POSSIBLY A
   TORNADO OR TWO. THE TORNADO THREAT MAY INCREASE BY EARLY EVE GIVEN
   EXPECTED STRENGTHENING OF LLJ /REF SWODY1/. THIS MAY REQUIRE THAT
   PARTS OF THE WW BE UPGRADED TO TORNADO BEFORE THAT TIME.

   AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
   TO 3 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 70
   KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 550. MEAN STORM
   MOTION VECTOR 24035.
