Areas affected...Southern MS...Southwest AL...Eastern LA
Concerning...Tornado Watch 588...
Valid 141920Z - 142045Z
The severe weather threat for Tornado Watch 588 continues.
SUMMARY...The threat for strong, long-track tornadoes continues.
DISCUSSION...Regional radar imagery continues to show numerous
discrete supercells, including a few which have rotational velocity
around 40 to 50 kt. The overall environment remain very conducive to
tornadic supercells with ample low-level moisture and buoyancy in
the presence of strong low to mid-level flow. Recent KLIX VAD data
shows increasing winds in the 1-2 km layer. This increase is likely
due to a mesoscale low-level jet, which is expected to move
northeastward across far southern MS and into southwest AL over the
next several hours. Attendant strengthening of the low-level shear
within this corridor could augment the already favorable conditions.
Surface observations also numerous gusts of 25 to 30 kt across
southeast LA.
Additionally, ongoing storms will likely strengthen as they approach
and interact the warm front, which now extends from about 50 miles
northwest of MEI southeastward to south of GZH in southern AL.
In all, the threat for strong, long-track tornadoes will continue
for at least the next few hours across eastern LA and southern MS,
eventually reaching southwest AL later this afternoon/early this
evening.
