   URGENT - IMMEDIATE BROADCAST REQUESTED
   SEVERE THUNDERSTORM WATCH NUMBER 28
   NWS STORM PREDICTION CENTER NORMAN OK
   1140 PM CST SAT FEB 9 2013
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   SEVERE THUNDERSTORM WATCH FOR PORTIONS OF 
   
          PARTS OF WEST CENTRAL AND NORTH CENTRAL TEXAS
   
   EFFECTIVE THIS SATURDAY NIGHT AND SUNDAY MORNING FROM 1140 PM
   UNTIL 700 AM CST.
   
   HAIL TO 2 INCHES 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 105
   STATUTE MILES EAST AND WEST OF A LINE FROM 20 MILES WEST
   NORTHWEST OF SHERMAN TEXAS TO 60 MILES SOUTH SOUTHEAST OF
   BROWNWOOD TEXAS.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
   ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU8).
   
   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...THUNDERSTORM ACTIVITY DEVELOPING ALONG AND AHEAD OF A
   COLD ADVANCING EASTWARD INTO AND THROUGH WEST CENTRAL AND NORTH
   TEXAS IS EXPECTED TO CONTINUE TO INCREASE IN COVERAGE AND INTENSIFY
   OVERNIGHT...AS MID-LEVEL COOLING AND LOW-LEVEL MOISTENING CONTRIBUTE
   TO FURTHER DESTABILIZATION.  IN THE PRESENCE OF 40-50 KT
   SOUTHWESTERLY DEEP LAYER MEAN FLOW AND STRONG SHEAR...AN
   INCREASINGLY ORGANIZED STORM CLUSTER COULD EVOLVE...WITH A RISK FOR
   STRONG SURFACE GUSTS...IN ADDITION TO LARGE HAIL.
   
   AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
   TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
   KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 450. MEAN STORM
