Areas affected...southern Mississippi

Concerning...Tornado Watch 186...

Valid 062307Z - 070030Z

The severe weather threat for Tornado Watch 186 continues.

SUMMARY...Supercells showing signs of intensification and increasing
tornado potential.

DISCUSSION...Supercells crossing the LA/MS border and across
southern MS have shown an uptick in intensity over the last 30
minutes. VAD profiles from HDC (Hammond,LA) show increasing the
850-700 mb flow beginning to be analyzed just south of the MS
border. This increase in the low to mid-level flow will aid in
increasing low level shear and thusly an increase in the tornado
threat this evening.

The cell moving into Walthall County MS has had a tornado reported
with it over the last 30 minutes. This cell will continue into a
favorable thermodynamic environment across southern MS, where
moderate to strong MLCAPE overlaps strong deep layer shear around
50-65 kts. This shows signs of cycling and strengthening. This will
continue to pose a risk for tornadoes including potential for a
strong tornado.

Two other supercells across Concordia County LA and across Copiah
County in MS are also become better organized in the low-levels.
These are also moving within a very favorable thermodynamic
environment and may also pose a risk for tornadoes over the next few
hours.
