   URGENT - IMMEDIATE BROADCAST REQUESTED
   SEVERE THUNDERSTORM WATCH NUMBER 47
   NWS STORM PREDICTION CENTER NORMAN OK
   235 PM EST TUE MAR 5 2013
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   SEVERE THUNDERSTORM WATCH FOR PORTIONS OF 
   
          EAST CENTRAL ALABAMA
          WESTERN AND NORTHERN GEORGIA
   
   EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 235 PM UNTIL
   900 PM EST.
   
   HAIL TO 1 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
   MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
   
   THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 85
   STATUTE MILES EAST AND WEST OF A LINE FROM 65 MILES NORTHEAST OF
   ROME GEORGIA TO 15 MILES SOUTH SOUTHEAST OF AUBURN ALABAMA.  FOR
   A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
   OUTLINE UPDATE (WOUS64 KWNS WOU7).
   
   REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
   FAVORABLE FOR 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. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
   DO PRODUCE TORNADOES.
   
   DISCUSSION...CONVECTION IS INTENSIFYING ALONG THE COLD FRONT IN
   CENTRAL AL...AND THIS TREND SHOULD PERSIST THROUGH THE AFTERNOON AS
   LOW-LEVEL MOISTENING AND WARMING CONTINUE ACROSS ERN AL INTO GA. 
   THOUGH INSTABILITY WILL REMAIN SOMEWHAT MARGINAL...STRONG VERTICAL
   SHEAR PROFILES WILL SUPPORT A RISK FOR DAMAGING WINDS WITH ORGANIZED
   LINE SEGMENTS AND PERHAPS SOME EMBEDDED SUPERCELL STRUCTURES.  THE
   TORNADO RISK IS MORE UNCERTAIN GIVEN MARGINAL
   MOISTURE/INSTABILITY...THOUGH STRONG LOW-LEVEL SHEAR THIS
   AFTERNOON/EVENING MAY SUPPORT AN ISOLATED SPINUP ACROSS GA. 
   OTHERWISE...MARGINALLY SEVERE HAIL WILL BE POSSIBLE WITH THE
   STRONGEST STORMS GIVEN RELATIVELY COOL MIDLEVEL TEMPERATURES AND THE
   REMNANTS OF A STEEP LAPSE RATE PLUME FROM THE W.
   
   AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
   TO 1 INCH. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60 KNOTS.
   A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 400. MEAN STORM MOTION
   VECTOR 27045.
