   NWS STORM PREDICTION CENTER NORMAN OK
   0925 PM CDT MON MAR 09 2009
   
   AREAS AFFECTED...PARTS OF CNTRL OK INTO SE KS AND SWRN MO
   
   CONCERNING...TORNADO WATCH 52...
   
   VALID 100225Z - 100330Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 52 CONTINUES.
   
   AN ADDITIONAL WW WILL LIKELY BE ISSUED BEFORE 03Z.
   
   MID/UPPER FORCING...ASSOCIATED WITH A LOW AMPLITUDE WAVE LIFTING OUT
   OF THE SOUTHERN ROCKIES...IS EXPECTED TO PROVIDE THE FOCUS FOR
   CONTINUED UPSCALE GROWTH OF CONVECTIVE DEVELOPMENT EAST NORTHEAST OF
   A WEAK FRONTAL WAVE MIGRATING EASTWARD ALONG THE KANSAS/ OKLAHOMA
   BORDER THROUGH 03-06Z.  MUCH OF THIS ACTIVITY MAY REMAIN ELEVATED
   ABOVE A LINGERING SURFACE WARM FRONT EXTENDING ACROSS SOUTHEAST
   KANSAS INTO THE OZARK PLATEAU...BUT AT LEAST SCATTERED STORMS MAY
   PERSIST ALONG A PRE-COLD FRONTAL CONFLUENCE ZONE JUST WEST OF A
   STRENGTHENING LOW-LEVEL JET AXIS.  
   
   ALTHOUGH THE PRIMARY LOW-LEVEL MOISTENING APPEARS TO BE OCCURRING
   ABOVE A DECOUPLING BOUNDARY LAYER...THE WARM SECTOR NEAR SURFACE AIR
   MASS STILL SEEMS MARGINALLY SUPPORTIVE OF TORNADIC POTENTIAL.  WITH
   CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS ENLARGING AS SOUTHERLY 850 MB
   LEVEL WINDS STRENGTHEN IN EXCESS OF 40-50 KTS...THE RISK OF A
   TORNADIC SUPERCELL CAN NOT BE RULED OUT.  HIGHEST PROBABILITY FOR
   THIS STILL SEEMS TO EXIST NEAR THE IMMEDIATE VICINITY OF THE WARM
   FRONT ACROSS SOUTHEASTERN KANSAS INTO SOUTHWESTERN MISSOURI. 
   BUT...AT LEAST A MARGINALLY SEVERE HAIL AND DAMAGING WIND THREAT IS
   EXPECTED TO CONTINUE ACROSS PARTS OF CENTRAL INTO NORTH
   CENTRAL/NORTHEAST OKLAHOMA SEVERAL MORE HOURS.
