Areas affected...parts of far eastern Louisiana into eastern
Mississippi and far western Alabama

Concerning...Tornado Watch 45...46...

Valid 151907Z - 152030Z

The severe weather threat for Tornado Watch 45, 46 continues.

SUMMARY...The most concerning tornado threat for the next 1 to 2
hours extends from south-central Mississippi vicinity to far
west-central Alabama.

DISCUSSION...Several supercells across southern Mississippi have
already produced intense to violent tornadoes, including 2 paths
within very close proximity from Walthall to Marion counties from
consecutive supercells. These supercells and a few others which have
recently developed across St. Helena and Tangipahoa Parishes are the
storms of greatest tornadic concern over the next 1 to 2 hours.
These supercells are in the centroid of the greatest STP (6+) and in
the closest proximity to the upper 70s to low 80s temperatures where
surface winds remain backed. Expect this environment to maintain
through the afternoon as a meso-low (~994mb) currently across
central Mississippi translates northeast at a similar speed to the
mean storm motion.
