   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1215 PM CDT WED JUN 04 2008
   
   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CENTRAL PLAINS
   AND MID ATLANTIC REGION THIS AFTERNOON AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS OVER PARTS
   OF THE CENTRAL PLAINS AND MID ATLANTIC REGION THIS AFTERNOON AND
   TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          DELAWARE
          NORTHERN KANSAS
          MARYLAND
          SOUTHERN NEBRASKA
          VIRGINIA
          EASTERN WEST VIRGINIA
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM...THE CENTRAL
   PLAINS THROUGH THE MID MS VALLEY...OH VALLEY AND MID ATLANTIC
   
   ...ERN WV THROUGH VA...MD AND DEL...
   
   THE ATMOSPHERE CONTINUES TO DESTABILIZE IN ADVANCE OF ONGOING LINE
   OF THUNDERSTORMS MOVING EAST ACROSS WV WITH MODERATE INSTABILITY
   ALREADY IN PLACE OVER VA. VERTICAL WIND PROFILES ARE FAVORABLE FOR
   THIS LINE OF STORMS TO CONTINUE DEVELOPING EAST INTO THE AXIS OF
   STRONGER INSTABILITY. THE LINE IS EXPECTED TO REMAIN ORGANIZED WITH
   A ROTATING COMMA HEAD ON ITS NRN END AS IT CONTINUES EWD THROUGH THE
   MID ATLANTIC. STEEP LOW LEVEL AND MID LEVEL LAPSE RATES ALONG WITH
   MODERATE INSTABILITY WILL SUPPORT A THREAT FOR CORRIDORS OF
   WIDESPREAD DAMAGING WIND. OTHER MORE DISCRETE STORMS MAY ALSO
   DEVELOP ALONG TRAILING OUTFLOW BOUNDARY AS WELL AS AHEAD OF THE
   LINE...AND THIS ACTIVITY WILL POSE A THREAT FOR LARGE
   HAIL...DAMAGING WIND AND ISOLATED TORNADOES.
   
   
   ...NRN KS THROUGH SRN AND CNTRL NEB...
   
   A WARM FRONT EXTENDS NORTHEAST THROUGH NE KS FROM A SURFACE LOW IN S
   CNTRL KS. RICH LOW LEVEL MOISTURE...STRONG SURFACE HEATING AND STEEP
   LAPSE RATES ARE CONTRIBUTING TO STRONG INSTABILITY IN THE VICINITY
   OF THIS BOUNDARY FROM NRN KS INTO SRN NEB. HOWEVER...THE ATMOSPHERE
   IS EXPECTED TO REMAIN CAPPED IN THIS REGION UNTIL LATE AFTERNOON OR
   EARLY EVENING WHEN AN INTENSIFYING SLY LOW LEVEL JET WILL INCREASE
   CONVERGENCE ALONG THE RETREATING FRONT AND RESULT IN THUNDERSTORM
   INITIATION. STRONG VERTICAL SHEAR PROFILES WILL SUPPORT SUPERCELLS
   WITH A THREAT OF VERY LARGE HAIL AND TORNADOES...A FEW OF WHICH
   COULD BE STRONG. OTHER STORMS MAY DEVELOP FARTHER WEST OVER THE HIGH
   PLAINS AND SPREAD EAST THROUGH  NEB DURING THE EVENING. THE PRIMARY
   THREAT WILL LIKELY TRANSITION TO DAMAGING WIND AND LARGE HAIL AS THE
   EVENING PROGRESSES.
   
   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.
