   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.
