Areas affected...southeast MS into far west-central AL

Concerning...Tornado Watch 702...

Valid 170012Z - 170215Z

The severe weather threat for Tornado Watch 702 continues.

SUMMARY...A corridor for enhanced tornado potential will extend in
the near term across southeast MS with a discrete supercell.  The
risk may continue into far west-central AL between 730-800pm CST.

DISCUSSION...Radar imagery shows a discrete supercell over Jones
County, MS with a messy supercell structure straddling Smith/Jasper
counties as of 610pm CST.  The low-level airmass is gradually
moistening along the MS/AL border with surface dewpoints immediately
downstream of the supercells slowly rising into the upper 60s
degrees F.  The observed 00z Slidell, LA sounding showed 1600 J/kg
MLCAPE and a 15 g/kg lowest 100mb mean mixing ratio.  Farther north
ahead of the aforementioned storms, RAP forecast soundings show
enlarged low-level hodographs with around 300-350 m2/s^2 0-1km SRH
and around 1000 J/kg MLCAPE.  The greater risk for a tornado or
series of tornadoes will likely accompany the discrete cell during
the next 1-2 hours.
