   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0500 AM CDT WED MAR 28 2007
   
   ...WIDESPREAD SEVERE THUNDERSTORMS EXPECTED OVER THE WESTERN HALF OF
   THE SOUTHERN AND CENTRAL PLAINS THIS AFTERNOON AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS OVER THE
   WESTERN HALF OF THE SOUTHERN AND CENTRAL PLAINS THIS AFTERNOON AND
   TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          WESTERN AND CENTRAL KANSAS
          SOUTHWEST INTO CENTRAL NEBRASKA
          WESTERN OKLAHOMA
          NORTHWEST TEXAS INCLUDING THE EASTERN PANHANDLE
   
   SURROUNDING THE MODERATE RISK AREA...THERE IS A SLIGHT RISK OF
   SEVERE THUNDERSTORMS FROM SOUTHWEST TEXAS NORTHWARD INTO SOUTH
   DAKOTA.
   
   A VERY INTENSE MID AND UPPER LEVEL SYSTEM WILL BRING EXTREMELY
   STRONG WIND FIELDS ALOFT OVER THE SOUTHERN AND CENTRAL HIGH PLAINS
   TODAY AND TONIGHT.  THIS SYSTEM IS CURRENTLY LOCATED OVER THE GREAT
   BASIN BUT WILL MAKE A SLOW EASTWARD PROGRESSION INTO THE CENTRAL
   ROCKIES DURING THIS PERIOD.  AHEAD OF THIS SYSTEM...A DRY LINE WILL
   BECOME WELL ESTABLISHED FROM A SURFACE LOW OVER FAR NORTHEASTERN
   COLORADO/NEBRASKA PANHANDLE SOUTHWARDS INTO WESTERN TEXAS. 
   INCREASING SOUTH TO SOUTHEASTERLY WINDS NEAR AND JUST ABOVE THE
   SURFACE WILL ALLOW AN INCREASINGLY HUMID AIR MASS TO SPREAD ACROSS
   THE WESTERN HALF OF THE PLAINS STATES DURING THE AFTERNOON.
   
   THOUGH AN AREA OF WARMER AIR JUST ABOVE THE SURFACE /A CAP/ WILL
   LIKELY INHIBIT THUNDERSTORM DEVELOPMENT FOR MUCH OF THE
   DAY...UNSEASONABLY WARM SURFACE TEMPERATURES AND INCREASED LIFT
   AHEAD OF APPROACHING SYSTEM WILL SUPPORT RAPID THUNDERSTORM
   DEVELOPMENT LATE IN THE AFTERNOON.  THE FIRST STORMS SHOULD FORM
   OVER THE CENTRAL HIGH PLAINS WITH DEVELOPMENT SOUTHWARD ALONG THE
   DRY LINE INTO THE EARLY EVENING AS THE CAP BREAKS INTO THE EASTERN
   TEXAS PANHANDLE AND WESTERN TEXAS.  THESE STORMS WILL BECOME SEVERE
   AND EVOLVE INTO SUPERCELLS QUITE RAPIDLY.  THE STRONGER STORMS ARE
   EXPECTED TO PRODUCE LARGE HAIL...SOME OF WHICH IS EXPECTED TO BE AS
   LARGE OR LARGER THAN BASEBALLS...ALONG WITH DAMAGING WINDS AND EVEN
   SEVERAL TORNADOES.  ANY TORNADOES WHICH CAN DEVELOP WILL HAVE THE
   POTENTIAL TO BECOME QUITE STRONG AND DAMAGING.  THIS ACTIVITY WILL
   LIKELY EVOLVE INTO LINES AND CLUSTERS AS THEY SPREAD EASTWARD WITH
   SEVERE THREAT LASTING WELL INTO THE NIGHT...WITH DAMAGING WINDS AND
   LARGE HAIL POSSIBLY BECOMING WIDESPREAD THROUGH THE EVENING.
   
   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 LATER TODAY.
