   URGENT - IMMEDIATE BROADCAST REQUESTED
   TORNADO WATCH NUMBER 378
   NWS STORM PREDICTION CENTER NORMAN OK
   235 PM CDT THU JUN 11 2009
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   TORNADO WATCH FOR PORTIONS OF 
   
          NORTHWEST AND CENTRAL TEXAS
   
   EFFECTIVE THIS THURSDAY AFTERNOON AND EVENING FROM 235 PM UNTIL
   1000 PM CDT.
   
   TORNADOES...HAIL TO 2.5 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 75 STATUTE
   MILES EAST AND WEST OF A LINE FROM 50 MILES EAST NORTHEAST OF
   LUBBOCK TEXAS TO 55 MILES SOUTH SOUTHWEST OF TEMPLE TEXAS.  FOR A
   COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
   UPDATE (WOUS64 KWNS WOU8).
   
   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.
   
   OTHER WATCH INFORMATION...CONTINUE...WW 375...WW 376...WW 377...
   
   DISCUSSION...STRONG SURFACE HEATING/DESTABILIZATION IS SUPPORTING
   INITIAL THUNDERSTORM DEVELOPMENT NEAR THE INTERSECTION OF THE
   DRYLINE AND A NW-SE OUTFLOW BOUNDARY NEAR BROWNWOOD.  A CORRIDOR OF
   LOW 70S BOUNDARY LAYER DEW POINTS AND SURFACE TEMPERATURES OF 95-100
   F NOSING INTO THE BOUNDARY INTERSECTION ZONE ARE RESULTING IN STRONG
   INSTABILITY /MLCAPE AOA 4000 J/KG/.  LOW-LEVEL AND DEEP LAYER SHEAR
   ARE SUFFICIENT FOR SUPERCELLS TO MOVE SEWD ALONG THE OUTFLOW
   BOUNDARY...AND THESE STORMS WILL BE CAPABLE OF PRODUCING A COUPLE OF
   TORNADOES...ISOLATED VERY LARGE HAIL...AND DAMAGING WINDS.  OTHER
   ISOLATED STORM DEVELOPMENT MAY OCCUR FARTHER NW TOWARD THE AREA SE
   OF LBB TO ABI ALONG THE STALLED BOUNDARY.  LATER THIS
   AFTERNOON/EVENING...STORM MERGERS/INTERACTIONS COULD LEAD TO THE
   FORMATION OF A CLUSTER OF HP SUPERCELLS/SMALL MCS WITH AN INCREASING
   THREAT FOR DAMAGING WINDS.
   
   AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
   SURFACE AND ALOFT TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE
   WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
   600. MEAN STORM MOTION VECTOR 32020.
