AREAS AFFECTED...WESTERN TENNESSEE TO FAR SOUTHERN KENTUCKY
CONCERNING...TORNADO WATCH 122...124...
VALID 051934Z - 052130Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 122, 124 CONTINUES.
SUMMARY...A DAMAGING WIND AND TORNADO THREAT IS EXPECTED TO PERSIST
THROUGH THE AFTERNOON.
DISCUSSION...A WELL-DEVELOPED SQUALL LINE CONTINUES ACROSS WESTERN
TENNESSEE. MEASURED WIND GUSTS HAVE BEEN MOSTLY IN THE 35 TO 45 KNOT
RANGE RECENTLY AS THE APEX OF THE BOW WEAKENED SOMEWHAT AS IT MOVED
INTO AN AIRMASS FEATURING LOW 50S TEMPERATURES. THE ONLY EXCEPTION
WAS A MEASURED 51 KT GUST AT KHKA AT 1917Z ON THE NORTHERN END OF
THE BOW. SOME ENHANCEMENT OF THIS BOW IS POSSIBLE OVER THE NEXT 1
TO 2 HOURS AS IT INTERACTS WITH A MORE UNSTABLE SURFACE AIRMASS
ALONG THE FRONT ACROSS SOUTHERN TENNESSEE WITH TEMPERATURES IN THE
LOW 80S AND DEWPOINTS IN THE MID 60S. IN ADDITION, SOME ENHANCEMENT
OF THE LOW-LEVEL JET (BETWEEN 1 AND 2 KM) HAS BEEN SAMPLED BY THE
KOHX VWP. THIS WILL FURTHER SUPPORT MAINTENANCE OF THE MCS AND ITS
ASSOCIATED WIND THREAT, AND WILL ALSO AID IN THE LOW-LEVEL SHEAR
FAVORABLE FOR SOME EMBEDDED TORNADO THREAT. EXPECT THE APEX OF THIS
BOW TO CONTINUE TO ORIENT ALONG THE INSTABILITY GRADIENT, ALONG AND
SLIGHTLY SOUTH OF I-40 BETWEEN MEMPHIS AND NASHVILLE, TN.
