Areas affected...southern Louisiana and far southern Mississippi

Concerning...Tornado Watch 720...

Valid 290000Z - 290100Z

The severe weather threat for Tornado Watch 720 continues.

SUMMARY...Threat for tornadoes and wind to continue across southern
Louisiana into far southern Mississippi.

DISCUSSION...A line of thunderstorms with embedded supercells
structures continues across portions of southern Louisiana into
Mississippi as of 00z. The environment across this region remains
highly favorable, with MLCAPE around 2000-2500 J/kg amid surface dew
points in the upper 60s to 70s. Forcing for ascent has begun to
gradually shift northward but strongly sheared profiles remain
favorable for supercell maintenance. VAD profiles from HDC (Hammond,
LA) show favorable curvature in the bottom 0-3 km, with 0-500m SRH
around 300 m2/s2. This in co*bination with favorable thermodynamics
will continue to support a risk for tornadoes, some of which may be
strong. Potential for damaging winds will also remain likely with
more linear storm modes. Local extension of WW720 has occurred
across southeastern LA into southern MS to cover this threat.
