   CONCERNING...TORNADO WATCH 52...
   
   VALID 100101Z - 100200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 52 CONTINUES.
   
   DISCRETE BOUNDARY LAYER BASED...OR NEAR BOUNDARY LAYER BASED...
   STORMS CONTINUE TO DEVELOP NORTHEASTWARD...JUST TO THE WEST OF THE
   OKLAHOMA CITY METRO AREA.  SURFACE TEMPERATURES HAVE BEGUN TO SLOWLY
   FALL...BUT AN INCREASE IN LOW-LEVEL MOISTURE IS ONGOING... MOSTLY
   WITHIN AN ELEVATED WARM ADVECTION REGIME ALONG/WEST OF A LOW-LEVEL
   JET AXIS WHICH HAS BEGUN TO STRENGTHEN ACROSS EASTERN OKLAHOMA INTO
   THE MISSOURI/KANSAS BORDER AREA.  AS THESE PROCESSES CONTINUE INTO
   THE 03-04Z TIME FRAME...STORMS MAY CONTINUE TO INCREASE WITHIN A
   LOW-LEVEL CONFLUENCE ZONE TO THE WEST OF THE LOW- LEVEL JET
   AXIS...FROM WEST CENTRAL OKLAHOMA INTO SOUTH CENTRAL/ SOUTHEAST
   KANSAS.  BUT...WITH THE EXCEPTION OF PERHAPS ALONG THE IMMEDIATE
   VICINITY OF THE WARM FRONTAL ZONE ACROSS SOUTHERN KANSAS...THE RISK
   FOR TORNADOES MAY DIMINISH.  LOCALLY DAMAGING WIND GUSTS WILL REMAIN
   A POSSIBILITY...HOWEVER.  TRAINING CELLS MAY ALSO BEGIN TO YIELD
   SOME HEAVY RAIN TOTALS.
