MESOSCALE DISCUSSION 0126
  NWS STORM PREDICTION CENTER NORMAN OK
  0212 PM CST THU FEB 24 2011
 
  AREAS AFFECTED...ERN AR...NRN MS...WRN/MIDDLE TN...WRN KY
 
  CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY
 
  VALID 242012Z - 242145Z
 
  WARM FRONT IS GRADUALLY LIFTING NWD ACROSS NERN AR/SRN TN WITH
  SUBSTANTIAL BREAKS IN BOUNDARY LAYER CLOUDS CONTRIBUTING TO
  STEEPENING OF LOW LEVEL LAPSE RATES AND DEEPENING CU FIELD.  LATEST
  SFC ANALYSIS SUGGESTS LOW IS BEGINNING TO DEEPEN OVER NWRN AR AND
  THIS FEATURE SHOULD PROGRESS ACROSS THE BOOT HEEL OF MO LATER THIS
  EVENING BEFORE LIFTING INTO WRN KY.  IT APPEARS FURTHER RECOVERY IS
  POSSIBLE IMMEDIATELY AHEAD OF SFC LOW BUT ONGOING
  CLOUDS/PRECIPITATION SHOULD LIMIT GREATER INSTABILITY FROM
  DEVELOPING INTO KY.  EVEN SO...VERY STRONG SHEAR WILL ENCOURAGE
  ROTATING UPDRAFTS AND SUPERCELLS CAN BE EXPECTED...ALONG WITH
  ISOLATED TORNADOES ALONG/SOUTH OF RETREATING WARM FRONT.
