AREAS AFFECTED...MIDDLE TN AND FAR NORTHERN AL
CONCERNING...SEVERE THUNDERSTORM WATCH 46...
VALID 111922Z - 112115Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 46
CONTINUES.
SUMMARY...MIXED DAMAGING WIND/MARGINAL SEVERE HAIL THREATS SHOULD
PERSIST THROUGH LATE AFTERNOON ACROSS MAINLY MIDDLE TENNESSEE INTO
FAR NORTHERN ALABAMA.
DISCUSSION...A COUPLE OF EMBEDDED SUPERCELLS WITHIN A BROKEN QLCS
HAVE YIELDED MARGINAL SEVERE HAIL AND DOWNED TREE REPORTS THUS FAR.
THE BOUNDARY LAYER REMAINS WARM AHEAD OF THIS ACTIVITY, WITH SURFACE
TEMPS MAINLY IN THE UPPER 70S TO LOWER 80S. THIS WILL SUSTAIN A
MIXED DAMAGING WIND/SEVERE HAIL THREAT OVER THE NEXT 2-3 HOURS. 18Z
BNA SOUNDING AND RECENT VWP DATA CONFIRM A NEARLY UNIDIRECTIONAL
SOUTHWESTERLY LOW-LEVEL WIND PROFILE WITH MODEST SPEED SHEAR. THIS
COULD SUPPORT A BRIEF TORNADO OR TWO, BUT SHOULD LARGELY REMAIN A
SECONDARY HAZARD. CONVECTION BUBBLING ON THE TRAILING PORTION OF THE
OUTFLOW ALONG THE MS/AL BORDER COULD YIELD AN UPTICK IN SEVERE
POTENTIAL ACROSS FAR NORTHERN AL.
