 PUBLIC SEVERE WEATHER OUTLOOK   NWS STORM PREDICTION CENTER NORMAN OK 0146 PM CST TUE NOV 30 2010  ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE SOUTHEAST AND SOUTHERN MID-ATLANTIC REGIONS THIS EVENING AND OVERNIGHT...  THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE POSSIBLE DEVELOPMENT OF TORNADOES...POTENTIALLY STRONG...AND DAMAGING WINDS OVER PARTS OF THE SOUTHEAST AND SOUTHERN MID-ATLANTIC REGIONS THIS EVENING AND OVERNIGHT.  CONDITIONS ARE EXPECTED TO SUPPORT THE POTENTIAL FOR A FEW STRONG AND POSSIBLY LONG-LIVED TORNADOES.  WHILE OVERALL SEVERE THUNDERSTORM COVERAGE IS NOT EXPECTED TO BE WIDESPREAD...THE POTENTIAL FOR A SIGNIFICANT TORNADO AFTER DARK WARRANTS HEIGHTENED SAFETY PRECAUTIONS.  TORNADOES DURING THE OVERNIGHT HOURS AT THIS TIME OF YEAR CAN BE PARTICULARLY DANGEROUS BECAUSE THEY ARE USUALLY FAST-MOVING AND OBSCURED BY RAIN AND DARKNESS.  THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE         CENTRAL AND EASTERN NORTH CAROLINA        NORTH-CENTRAL AND NORTHEASTERN SOUTH CAROLINA        SOUTH-CENTRAL VIRGINIA  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 TONIGHT.  ..RACY.. 11/30/2010
