   DAY 1 CONVECTIVE OUTLOOK

   ...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF THE CENTRAL
   PLAINS/MS VALLEY...
   
   ...PLAINS/MS VALLEY REGION...
   STG/SVR TSTMS ARE EXPECTED TO CONTINUE FOR A FEW MORE
   HOURS...ESPECIALLY ALONG THE MO RIVER FROM SOUTH OF THE OMA AREA
   SEWD THROUGH WCENTRAL MO WHERE TSTMS HAVE MERGED INTO
   CLUSTERS/OCCASIONAL BOWING SEGMENTS. THIS REGION IS ALSO BENEATH
   RELATIVELY STRONGER MID-LEVEL FLOW ASSOCIATED WITH WEAK DISTURBANCES
   EMBEDDED IN NWLY FLOW. DESPITE SUBSTANTIAL CONVECTION THIS
   AFTERNOON/EARLY EVENING...SUFFICIENT INSTABILITY REMAINS IN PLACE
   FOR A CONTINUED SVR THREAT OF DAMAGING WINDS/LARGE HAIL THROUGH THE
   EVENING HOURS. A MORE CONCENTRATED THREAT MAY EXIST FROM
   WEST-CENTRAL THROUGH CENTRAL MO WHERE A SEWD-MOVING CLUSTER OF SVR
   TSTMS WILL INTERSECT A NWD-MOVING OUTFLOW BOUNDARY...LOCALLY
   ENHANCING CONVERGENCE AND STORM-SCALE INTERACTIONS. 
   
   ...OHIO VALLEY...
   A LINGERING FRONTAL BOUNDARY LOCATED ON THE SRN FRINGES OF MODEST
   WLY MID-LEVEL FLOW WILL SERVE AS A FOCUS FOR ISOLATED SVR TSTMS WITH
   A RISK FOR DAMAGING WINDS AND PERHAPS HAIL. 
   
   ...SRN AZ...
   A DEEPLY-MIXED BOUNDARY LAYER WILL RESULT IN A CONTINUED SVR WIND
   THREAT FOR A FEW MORE HOURS AS TSTMS MOVE WWD FROM HIGHER TERRAIN
   INTO A MORE UNSTABLE AIR MASS.
   
   ...PORTIONS OF MT/ID...
   DISTURBANCES WITHIN SWLY FLOW ALOFT WILL CONTINUE TO SUPPORT
   DEVELOPMENT OF ISOLATED STG/SVR TSTMS WHERE INSTABILITY IS
   MAXIMIZED...WITH DEW POINTS IN THE LOWER 50S LEADING TO MLCAPE OF
   500-1000 J/KG. DAMAGING WINDS SHOULD CONTINUE TO BE THE PRIMARY
   THREAT.
   
   ...SRN PLAINS...
   A DAMAGING WIND THREAT WILL EXIST FOR A FEW MORE HOURS WITH CLUSTERS
   OF TSTMS MOVING SWD IN AN ENVIRONMENT WITH STEEP LOW-LEVEL LAPSE
   RATES/LARGE TEMP-DEW POINT SPREADS.
