Areas affected...Central/Southeast LA...Southwest MS

Concerning...Severe potential...Watch unlikely=20

Valid 241255Z - 241500Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated damaging gusts and/or a brief tornado are
possible for the next few hours across central and southeast
Louisiana and southwest Mississippi.

DISCUSSION...Recent regional radar imagery shows a convective line
from central MS southwestward into southwest LA. This line is moving
slowly eastward, while cells within the line move quickly to the
northeast. Line-parallel orientation of the deep-layer vertical
shear has resulted in a largely anafrontal/undercut storm character
and limited severe potential thus far. This trend is expected to
continue, particularly with the northern extent of the line across
central and southwest MS where low-level stability and related
convective inhibition exist.=20

Farther south (across central and eastern LA), ample low-level
moisture has resulted in limited convective inhibition, but poor
lapse rates are limiting buoyancy as well. Even so, a few stronger
updrafts are possible as the line pushes eastward, particularly if
favorable storm interactions/cell mergers occur. Primary severe
threat is isolated, water-loaded downbursts capable of damaging
gusts. Veering low-level winds also support a low-probability
potential for a brief tornado with any warm sector updrafts that can
deepen and mature.
