   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0511 AM CDT TUE OCT 26 2010
   
   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE OHIO AND
   TENNESSEE VALLEYS AND GREAT LAKES...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF WIDESPREAD DAMAGING WINDS AND A FEW TORNADOES OVER
   PARTS OF THE OHIO AND TENNESSEE VALLEYS AND GREAT LAKES TODAY
   THROUGH EARLY WEDNESDAY
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          EASTERN ILLINOIS
          INDIANA
          NORTHERN KENTUCKY
          SOUTHERN MICHIGAN
          WESTERN AND CENTRAL OHIO
   
   ELSEWHERE...SEVERE STORMS ALSO ARE POSSIBLE FROM THE LOWER
   MISSISSIPPI VALLEY NORTHEASTWARD INTO THE APPALACHIANS AND LOWER
   GREAT LAKES
   
   A POWERFUL JET STREAM DISTURBANCE...WITH WINDS IN EXCESS OF 175
   MILES PER HOUR...WILL MOVE FROM THE CENTRAL ROCKIES ACROSS THE
   CENTRAL PLAINS INTO OHIO VALLEY LATER TODAY AND TONIGHT.
   
   AT THE SAME TIME...AN INTENSE SURFACE LOW ASSOCIATED WITH THE JET
   WILL FURTHER STRENGTHEN AS IT TRACKS SLOWLY NORTHEAST FROM MINNESOTA
   INTO WESTERN ONTARIO.
   
   A COLD FRONT TRAILING SOUTH FROM THE LOW WILL SERVE AS THE MAIN
   FOCUS FOR THUNDERSTORM DEVELOPMENT THROUGH EARLY WEDNESDAY AS THE
   FRONT ACCELERATES EAST ACROSS THE OHIO AND TENNESSEE VALLEYS
   TODAY...AND ACROSS THE LOWER GREAT LAKES AND THE APPALACHIANS
   TONIGHT/EARLY WEDNESDAY.
   
   THE VERY STRONG WINDS ASSOCIATED WITH THE LOW...AND INCREASING
   MOISTURE SPREADING RAPIDLY NORTH FROM THE GULF COAST STATES...WILL
   ALLOW THE THUNDERSTORMS TO ORGANIZE INTO BANDS THAT WILL BE CAPABLE
   OF PRODUCING SWATHS OF DAMAGING WIND AND A FEW STRONG TORNADOES.
   
   WHILE THE GREATEST RISK OF SEVERE WEATHER IS EXPECTED TO OCCUR
   DURING THE DAY TODAY OVER THE OH AND TENNESSEE VALLEYS...A MORE
   LIMITED THREAT FOR HIGH WIND AND ISOLATED TORNADOES WILL CONTINUE
   THROUGH EARLY WEDNESDAY EASTWARD INTO THE APPALACHIANS AND THE LOWER
   GREAT LAKES.
   
   STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY
   VERY DANGEROUS SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO
   REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO
   RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE
   WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
