THE SEVERE WEATHER THREAT FOR TORNADO WATCH 559...564...CONTINUES.

DISCUSSION...RECENT RADAR TRENDS SHOW DISCRETE SUPERCELLS PERSISTING
ACROSS FAR NERN MS AND INTO MIDDLE TN...EXHIBITING STRONG LOW-LEVEL
ROTATION WITH THE POTENTIAL FOR TORNADOES. THESE STORMS ARE
APPROACHING THE ERN EDGE OF THE INSTABILITY AXIS...WITH A MORE
MARGINAL THERMODYNAMIC ENVIRONMENT NOTED DOWNSHEAR IN THE 24/00Z BNA
SOUNDING. HOWEVER...VERY STRONG DEEP-LAYER WIND PROFILES AND A

WILL SHIFT PRIMARILY INTO MIDDLE TN AND NWRN AL OVER THE NEXT HR OR
SO. A LINGERING THREAT COULD EXTEND PAST 02Z ACROSS PARTS OF NRN MS
