CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 261907Z - 262000Z

BOUNDARY LAYER THERMALS HAVE RECENTLY INTENSIFIED ACROSS MUCH OF
CENTRAL KY INTO MIDDLE TN WHERE PARTIAL SUNSHINE HAS STEEPENED LOW
LEVEL LAPSE RATES.  LATEST VIS IMAGERY SUGGESTS DEEPENING SHOWERS
HAVE EVOLVED ALONG WRN EDGE OF THICKER WARM ADVECTION CLOUD SHIELD.
THESE ECHOES ARE EVOLVING WITHIN A FAVORABLE SHEAR ENVIRONMENT FOR
STORM ROTATION...HOWEVER ASIDE FROM BROAD CYCLONIC FLOW THIS REGION
IS NOT TERRIBLY CONVERGENT.  CONFIDENCE IN SUSTAINED ORGANIZED
UPDRAFTS IS SOMEWHAT QUESTIONABLE...AT LEAST AT THIS TIME.  WILL
MONITOR FOR POSSIBLE UPWARD STORM-SCALE GROWTH AND POSSIBLE WW.
