Areas affected...east-central Mississippi into central Alabama

Concerning...Tornado Watch 50...

Valid 252045Z - 252245Z

The severe weather threat for Tornado Watch 50 continues.

SUMMARY...Conditions remain favorable for tornadic supercells
through this afternoon.

DISCUSSION...The air mass remains unstable ahead of a broken line of
cells from east-central MS into north-central AL, with southerly
surface winds and warmer temperatures over southern AL aiding
destabilization. Although these storms are aligned roughly parallel
to the strong southwesterlies aloft, low-level winds remain
sufficiently backed to maintain favorable low-level SRH for
supercells and tornadoes. Effective SRH from objective analysis and
from area VWPs exceeds 300 m2/s2, with values over 400 m2/s2 for a
right-moving cell.

Additional cells have recently intensified over southern MS, and
these may become better organized as they proceed east into the
stronger low-level shear environment.
