   URGENT - IMMEDIATE BROADCAST REQUESTED
   SEVERE THUNDERSTORM WATCH NUMBER 160
   NWS STORM PREDICTION CENTER NORMAN OK
   330 PM CDT WED MAY 15 2013
   
   THE NWS STORM PREDICTION CENTER HAS ISSUED A
   
   * SEVERE THUNDERSTORM WATCH FOR PORTIONS OF 
     SOUTHERN OKLAHOMA
     NORTHWEST TEXAS
   
   * EFFECTIVE THIS WEDNESDAY AFTERNOON FROM 330 PM UNTIL MIDNIGHT
     CDT.
   
   * PRIMARY THREATS INCLUDE...
     SEVERAL VERY LARGE HAIL EVENTS TO 2 INCHES IN DIAMETER POSSIBLE
     SEVERAL DAMAGING WIND GUSTS TO 70 MPH POSSIBLE
   
   THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 80
   STATUTE MILES NORTH AND SOUTH OF A LINE FROM 90 MILES WEST
   NORTHWEST OF ABILENE TEXAS TO 15 MILES EAST SOUTHEAST OF DURANT
   OKLAHOMA.  FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
   ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU0).
   
   PRECAUTIONARY/PREPAREDNESS ACTIONS...
   
   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...COMPLEX STORM EVOLUTION ANTICIPATED THROUGH THE EVENING
   AS LIFT AND SHEAR ASSOCIATED WITH AND UPPER LOW FORMING OVER CENTRAL
   OK ACT ON VERY UNSTABLE AIRMASS AHEAD OF TX DRYLINE AND ALONG/SOUTH
   OF RED RIVER WARM FRONT. CURRENT CLUSTERS OF STORMS DEVELOPING
   ACROSS THE WARM FRONT IN SCNTRL OK WILL CONTINUE TO POSE A
   MARGINALLY SEVERE HAIL THREAT WITH STORM INTERACTIONS/MERGERS
   POSSIBLY RESULTING IN BRIEFLY STRONGER UPDRAFTS AND A LOW CHANCE FOR
   DAMAGING WINDS AND EVEN A TORNADO. WITH TIME FOCUS SHOULD SHIFT
   SOUTH AND WEST AS SHEAR AND LIFT STRENGTHEN SOUTH OF THE MID/UPPER
   LOW. PROXIMITY TO STRONGER INSTABILITY ACROSS THIS PORTION OF THE
   WATCH SHOULD SUPPORT ROBUST UPDRAFTS AND POSSIBLY A FEW SUPERCELLS
   WITH LARGE HAIL AND HIGH WINDS. EVENTUALLY SOME OF THIS ACTIVITY
   WILL MERGE INTO ONE OR TWO CONVECTIVE SYSTEMS AND SPREAD ESEWD
   ACROSS THE INSTABILITY AXIS THROUGH THE EVENING. TORNADO POTENTIAL
   MAY INCREASE IF CONVECTION REMAINS DISCRETE AND INTERACTS WITH
   RESIDUAL STORM-SCALE/MESOSCALE BOUNDARIES DURING THE EVENING. IF
   THIS POTENTIAL BECOMES EVIDENT...PARTS OF THE REGION MAY NEED TO BE
   UPGRADED TO A TORNADO WATCH.
   
   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 500. MEAN STORM
   MOTION VECTOR 27025.
