Areas affected...Central MS
Concerning...Severe potential...Watch possible=20
Valid 101001Z - 101200Z
Probability of Watch Issuance...40 percent
SUMMARY...Isolated damaging gusts and potentially a brief tornado
are possible across central Mississippi over the next few hours.
DISCUSSION...Convective line stretching from northern MS
southwestward through central LA has shown a bit more forward
propagation over the past hour or so, as this portion of the line
becomes more perpendicular to the deep-layer shear vector. The
strongest updrafts within the line now exist over central MS, where
a few bowing segments currently exist. Recent VAD profile from KDGX
sample 220-225 m2/s2 of 0-1 km storm-relatively helicity over the
past half hour, which matches well with a small maximum in 0-1 km storm-relatively helicity in the same region on the mesoanalysis.
However, low-level stability persists across the region, with recent mesoanalysis and forecast soundings estimating substantial
convective inhibition remains in place. Even so, a few damaging
gusts may still be able to reach the surface. Additionally, any
sustained mesovortex may be able to produce a brief tornado.
However, the low-level stability is expected to keep the overall
severe potential low, despite the favorable kinematics.
