   ...THERE IS A SLGT RISK OF SVR TSTMS FROM WRN OH WW INTO THE MIDDLE
   MO VALLEY...
   
   ...MIDDLE OH VALLEY WWD INTO THE MIDDLE MO VALLEY...
   SCATTERED SHOWERS AND THUNDERSTORMS ARE ONGOING ATTM FROM E CENTRAL
   INDIANA WWD INTO ERN NEB -- ALONG COMBINATION WARM FRONT /
   CONVECTIVE OUTFLOW S OF WIDESPREAD PRECIPITATION AREA OVER THE UPPER
   GREAT LAKES REGION.  STRONGEST STORMS ATTM EXIST OVER CENTRAL AND
   ERN INDIANA...WHERE MODERATE INSTABILITY AND MARGINAL SHEAR SUGGEST
   MULTICELL / WEAK SUPERCELL STORMS CAPABLE OF HAIL / LOCALLY DAMAGING
   WIND GUSTS.  SEVERE THREAT SHOULD SLOWLY DIMINISH WITH TIME ACROSS
   THIS REGION AFTER SUNSET.  
   
   STORMS ARE ALSO FORECAST TO INCREASE THIS AFTERNOON AND EVENING
   ACROSS ERN NEB / WRN IA AHEAD OF WEAK COLD FRONT / INVOF WEAK UPPER
   VORT MAX MOVING SLOWLY EWD ACROSS THIS AREA.  THOUGH INSTABILITY IS
   SOMEWHAT WEAKER THAN ACROSS THE OH VALLEY...THIS SHOULD BE OFFSET BY
   SLIGHTLY STRONGER DEEP-LAYER WIND FIELD.  EXPECT THREAT FOR LOCALLY
   DAMAGING WINDS / HAIL TO EVOLVE...AND SHIFT EWD TOWARD NRN IL INTO

   DEVELOPMENT THIS AFTERNOON / EVENING.  THOUGH DEEP LAYER FLOW 
   DECREASES WITH SWD EXTENT...SHEAR SHOULD BE SUFFICIENT FROM ROUGHLY
   NERN CO / NWRN KS NWD TO SUPPORT LOCALLY STRONG / SEVERE STORMS /
   STORM CLUSTERS CAPABLE OF PRODUCING LOCALLY DAMAGING WINDS / HAIL
   INTO THE OVERNIGHT HOURS.
   
   ...COASTAL NEW ENGLAND...
   SCATTERED TO ISOLATED CONVECTION CONTINUES TO DEVELOP FROM SERN ME
   SWD INTO ERN MA...WITHIN LOW-LEVEL CONVERGENCE ZONE ALONG SEA-BREEZE
   BOUNDARY...WHERE AIRMASS HAS BECOME MODERATELY UNSTABLE.  WITH
   MID-LEVEL FLOW 30 TO 40 KT...ONE OR TWO STRONGER STORMS MAY
   EVOLVE..CAPABLE OF PRODUCING LOCALLY STRONG / GUSTY WINDS OR
   MARGINAL HAIL. THREAT SHOULD DIMINISH THROUGH EVENING AS BOUNDARY
