AREAS AFFECTED...KY...TN
CONCERNING...SEVERE THUNDERSTORM WATCH 722...
VALID 032343Z - 040045Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 722
CONTINUES.
ONLY ISOLATED TSTM DEVELOPMENT OCCURRED EARLIER ACROSS WATCH 722 AND
ALONG THE COLD FRONT NEAR AND SOUTH OF THE OH RIVER. IF CURRENT
TRENDS HOLD...MUCH OF WATCH 722 MAY BE CANCELED PRIOR TO EXPIRATION.
MORE WIDELY-SPACED STORM DEVELOPMENT HAS OCCURRED NEAR THE FRONT AND
ALONG SEVERAL WEAK LOW LEVEL CONFLUENT/CONVERGENT BOUNDARIES AHEAD
OF THE FRONT...FROM THE MO BOOTHEEL TO MIDDLE TN. THE MO BOOTHEEL
STORM HAS BEEN ONE OF THE MORE INTENSE STORMS THIS EVENING AND HAS
UNDERGONE AN INTERESTING TRANSFORMATION FROM ONE TO SEVERAL DISCRETE
UPDRAFTS OVER THE PAST HOUR. PULSE/MULTICELL NATURE OF THIS
DEVELOPMENT SUGGESTS THAT DEEP-LAYER FLOW/SHEAR ALONG THIS PORTION
OF THE FRONT IS PROBABLY LIMITED BUT MAGNITUDE OF INSTABILITY IS
QUITE HIGH.
ADDITIONAL ISOLATED SEVERE STORM DEVELOPMENT MAY OCCUR SOUTH OF
WATCH 722...IN TN...OVER THE NEXT COUPLE OF HOURS. AT THIS TIME
STRONGER MID LEVEL FLOW AND ABUNDANT INSTABILITY ACROSS THESE AREAS
COULD ALLOW ONE OR TWO STORMS TO PERSIST AND POSE A THREAT OF
DAMAGING WINDS AND HAIL. THIS AREA WILL CONTINUE TO BE MONITORED FOR
A WATCH OVER THE NEXT HOUR OR SO.
