   DEVELOPMENT OF DAMAGING WINDS...LARGE HAIL...AND TORNADOES FROM THE
   MID MISSISSIPPI VALLEY INTO THE OHIO VALLEY AND CENTRAL APPALACHIANS

   A SEASONABLY STRONG JET STREAM DISTURBANCE NOW OVER COLORADO WILL
   TRACK EAST INTO NEBRASKA TODAY AND INTO THE MID MISSISSIPPI VALLEY
   TONIGHT...BEFORE REACHING THE LOWER GREAT LAKES EARLY SATURDAY.
   
   AHEAD OF THE DISTURBANCE...A BROAD CURRENT OF VERY WARM...MOIST

   AS DAYTIME HEATING FURTHER DESTABILIZES THE REGION...NUMEROUS STRONG

   CONDITIONS WILL BE FAVORABLE FOR THE STORMS TO ORGANIZE INTO
   LONG-LIVED...BOW-SHAPED BANDS.
   
   WINDS IN THE MIDDLE AND UPPER LEVELS OF THE ATMOSPHERE WILL INCREASE
   OVER THE MISSISSIPPI AND OHIO RIVER VALLEYS LATER TODAY AND TONIGHT
   WITH THE CONTINUED EASTWARD MOTION OF THE COLORADO UPPER IMPULSE. 
   COUPLED WITH THE VERY WARM AND HUMID CONDITIONS PRESENT AT LOWER
   LEVELS...THIS SETUP MAY YIELD SEVERAL SWATHS OF DAMAGING
   THUNDERSTORM WINDS...AREAS OF LARGE HAIL...AND A FEW TORNADOES.
   
   WHILE THE STORMS SHOULD BE MOST WIDESPREAD THIS AFTERNOON THROUGH
   EARLY TONIGHT...A MORE LIMITED SEVERE THREAT WILL CONTINUE THROUGH
   EARLY SATURDAY...ESPECIALLY FROM INDIANA EAST INTO THE CENTRAL
   APPALACHIANS AND MID ATLANTIC STATES.

   SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE
   WEATHER SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA
