   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1144 AM CDT THU APR 18 2013
   
   ...SEVERE THUNDERSTORMS ARE EXPECTED ACROSS PARTS OF THE MISSISSIPPI
   AND LOWER OHIO VALLEYS INTO PARTS OF THE GREAT LAKES REGION TODAY...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF WIDESPREAD DAMAGING WINDS AND A FEW TORNADOES OVER
   PARTS OF THE MISSISSIPPI AND LOWER OH VALLEYS TODAY.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          EASTERN ARKANSAS
          SOUTHERN ILLINOIS
          MUCH OF INDIANA
          WESTERN KENTUCKY
          SOUTHERN LOWER MICHIGAN
          SOUTHEAST MISSOURI
          NORTHERN MISSISSIPPI
          WEST TENNESSEE
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM EAST TEXAS
   NORTHWARD ACROSS MUCH OF THE MISSISSIPPI AND OHIO VALLEYS INTO THE
   GREAT LAKES REGION.
   
   A POWERFUL UPPER STORM SYSTEM OVER THE PLAINS WILL MOVE EASTWARD
   TODAY AND AFFECT THE MISSISSIPPI AND OHIO VALLEYS.  A FAST-MOVING
   LINE OF THUNDERSTORMS AHEAD OF THE STORM SYSTEM WILL SWEEP ACROSS
   THE RISK AREA TODAY INTO THIS EVENING.  STRONG WINDS ALOFT COUPLED
   WITH A MOIST AND UNSTABLE AIR MASS WILL PROVIDE THE POTENTIAL FOR
   RATHER WIDESPREAD DAMAGING WINDS WITH THE LINE.  SOME OF THE GUSTS
   COULD BE LOCALLY STRONG TO EXTREME...PARTICULARLY ACROSS PARTS OF
   SOUTH CENTRAL THROUGH NORTHEAST INDIANA AND NORTHWEST OHIO BY LATE
   AFTERNOON.  OTHERWISE...A FEW TORNADOES ARE POSSIBLE WITH STORMS
   WITHIN AND AHEAD OF THE LINE.
   
   STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
   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.
