   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0402 AM CDT WED JUN 12 2013
   
   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE UPPER MIDWEST
   INTO THE OHIO VALLEY THIS AFTERNOON AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF WIDESPREAD DAMAGING WINDS...LARGE HAIL AND A FEW
   TORNADOES OVER PARTS OF THE UPPER MIDWEST INTO THE OHIO VALLEY THIS
   AFTERNOON AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          EASTERN IOWA
          NORTHERN AND CENTRAL ILLINOIS
          MUCH OF INDIANA
          WESTERN OHIO
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE IN SURROUNDING
   AREAS...INCLUDING PARTS OF THE MIDDLE MISSISSIPPI VALLEY...SOUTHERN
   GREAT LAKES...CENTRAL APPALACHIANS AND MID ATLANTIC COAST
   STATES...AS WELL AS ACROSS PARTS OF THE NORTHERN ROCKIES INTO
   ADJACENT HIGH PLAINS.
   
   THE ENVIRONMENT IS BECOMING VERY MOIST AND UNSTABLE ALONG A STALLED
   FRONTAL ZONE EXTENDING FROM THE MID ATLANTIC COAST WEST
   NORTHWESTWARD THROUGH THE OHIO VALLEY...TO A DEVELOPING AREA OF LOW
   PRESSURE ACROSS THE MIDDLE MISSOURI VALLEY.  THIS LOW IS EXPECTED TO
   BECOME THE FOCUS FOR INTENSE THUNDERSTORM DEVELOPMENT AS IT TRACKS
   EASTWARD ACROSS EASTERN IOWA INTO NORTHERN ILLINOIS THIS
   AFTERNOON...WHERE CONDITIONS LIKELY WILL BECOME CONDUCIVE TO THE
   EVOLUTION OF A LARGE AND ORGANIZED CLUSTER OF STORMS.  THIS ACTIVITY
   IS THEN EXPECTED TO SPREAD RAPIDLY EAST SOUTHEASTWARD ACROSS
   SOUTHERN PORTIONS OF THE GREAT LAKES REGION...AND SOUTHWARD TOWARD
   THE LOWER OHIO VALLEY....LATE THIS AFTERNOON AND EVENING. 
   WIDESPREAD STRONG...POTENTIALLY DAMAGING...WIND GUSTS ARE
   POSSIBLE...ALONG WITH THE RISK FOR LARGE HAIL.  A FEW TORNADOES ARE
   ALSO POSSIBLE...PARTICULARLY WITH EARLY STORMS ACROSS PARTS OF
   EASTERN IOWA INTO NORTHERN ILLINOIS.
   
   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.
