Areas affected...western Tennessee into northern Mississippi

Concerning...Tornado Watch 59...

Valid 280142Z - 280315Z

The severe weather threat for Tornado Watch 59 continues.

SUMMARY...A replacement tornado watch will be issued, which will
extend farther south into northern Mississippi.

DISCUSSION...Numerous storms persist from southern AR into TN, with
supercells approaching northwest MS over the next 1-2 hours. MLCAPE
over 2000 J/kg remains over the region owing to a very moist air
mass. Strong southwesterlies aloft are resulting in long hodographs,
with southerly low-level flow aiding supercell potential as well.
Area VWPs show effective SRH generally averaging 200-300 m2/s2,
which will support a continued supercell threat. While cellular
storm mode is likely for a few hours, the eventual arrival of the
cold front as well as merging outflows may result in a linear mode
later tonight. All modes of severe will be possible.
