Areas affected...Portiosn of western/middle TN

Concerning...Severe Thunderstorm Watch 406...

Valid 200537Z - 200630Z

The severe weather threat for Severe Thunderstorm Watch 406
continues.

SUMMARY...Damaging winds should continue to spread eastward across
western and middle TN over the next couple of hours. A small
northward extension in area may be needed for Severe Thunderstorm
Watch 406.

DISCUSSION...A small bowing complex that earlier produced a 58 kt
wind gust at the Memphis airport will continue moving eastward
around 40-45 kt across parts of western/middle TN early this
morning. The airmass downstream of this convection remains at least
weakly unstable, and storm organization will probably be maintained
for the next hour or two with a strengthening southwesterly
low-level jet. Strong to damaging winds remain the primary threat,
with velocity data from KNQA showing 50-60+ kt outbound wind
signature northeast of Memphis. Part of this line will approach the
northern edge of Severe Thunderstorm Watch 406 in the next hour, and
a small extension northward in area may be warranted if current
radar trends continue.
