Areas affected...Parts of eastern TN...northern AL...and far
northwest GA

Concerning...Severe Thunderstorm Watch 519...

Valid 180924Z - 181030Z

The severe weather threat for Severe Thunderstorm Watch 519
continues.

SUMMARY...WW may be canceled early (prior to 11Z) across eastern TN,
northern AL, and far northwest GA as low-topped convection undergoes
further weakening.

DISCUSSION...Trends in infrared satellite imagery showed warming
cloud tops from middle TN to central MS.  This combined with a great
reduction in lightning and recent wind gusts with the low-topped
convection being sub-severe suggests the overall severe-weather
threat should continue to wane, such WW 519 may be canceled prior to
11Z.
