Areas affected...Northeast Mississippi...Northwest Alabama...and far
southern Tennessee

Concerning...Tornado Watch 702...

Valid 162245Z - 162345Z

The severe weather threat for Tornado Watch 702 continues.

SUMMARY...The threat for tornadoes and damaging winds continues
through the evening.

DISCUSSION...A mature bowing segment with a comma-head type feature
is crossing from Northeast Mississippi into northwest Alabama at
2230Z. This feature has numerous areas of rotation with at least one
TDS observed. In addition, some embedded supercells with strong
rotation are apparent north and south of this feature along the
line. Expect the damaging wind/tornado threat to continue into the
evening through at least northwest Alabama. There is considerably
more uncertainty in northeast Alabama where instability is currently
limited with dewpoints in the upper 50s. Some northward transport of
the better dewpoints and additional destabilization may occur over
the next few hours. This limited instability may reduce the overall
tornado threat once the line reaches northeast Alabama, but the
low-level jet will also be strengthening over the next 2 to 4 hours
which may sustain a threat farther east than the marginal
instability would otherwise suggest.
