The bulletin from the National Weather Service is below:

URGENT - IMMEDIATE BROADCAST REQUESTED

   125 PM EDT WED APR 27 2011
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   TORNADO WATCH FOR PORTIONS OF 
   
          CENTRAL MARYLAND
          CENTRAL NORTH CAROLINA
          CENTRAL VIRGINIA
          EASTERN WEST VIRGINIA
          COASTAL WATERS
   
   EFFECTIVE THIS WEDNESDAY AFTERNOON AND EVENING FROM 125 PM UNTIL 800 PM EDT. 
   TORNADOES...HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND
   GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
   AREAS.
   
   THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 60 STATUTE
   MILES EAST AND WEST OF A LINE FROM 25 MILES NORTH NORTHWEST OF
   MARTINSBURG WEST VIRGINIA TO 25 MILES SOUTH OF SOUTHERN PINES
   NORTH CAROLINA.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
   ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU3).
   
   REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
   TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
   AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
   THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
   AND POSSIBLE WARNINGS.

DISCUSSION...SCATTERED THUNDERSTORMS ARE INCREASING ACROSS PORTIONS
   OF NC/VA IN REGION OF WARM/MOIST AND UNSTABLE AIR MASS.  INCREASING
   MID AND LOW LEVEL WIND FIELDS THROUGH THE DAY SUGGEST A RISK OF
   ORGANIZED/SUPERCELL STORMS CAPABLE OF LARGE HAIL AND DAMAGING WINDS.
    THE TORNADO THREAT IS NOT PARTICULARLY HIGH...BUT SUFFICIENT LOW
   LEVEL SHEAR IS PRESENT FOR A RISK OF ISOLATED SPIN UPS IN THE MOST
   INTENSE SUPERCELLS.
