Areas affected...Northern MS...northwest AL...southwest TN
Concerning...Tornado Watch 124...125...
Valid 052318Z - 060045Z
The severe weather threat for Tornado Watch 124, 125 continues.
SUMMARY...The threat for tornadoes, damaging wind, and isolated hail
will spread eastward through the evening.
DISCUSSION...A small storm cluster with embedded supercells has
evolved across north-central MS this evening, with another cluster
noted into southwest TN. The environment downstream of the southern
cluster remains favorable for tornadic supercells, with strong
buoyancy (with MLCAPE of 2000-3000+ J/kg), favorable boundary-layer
moisture and deep-layer shear, and locally backed surface winds
supporting 0-1 km SRH above 200 m2/s2. Despite the complex storm
mode, the presence of embedded supercells within this environment
will continue to support a tornado threat, including strong-tornado
potential. One or more swaths of severe/damaging wind will also be
possible with these clusters, along with isolated hail.
Buoyancy is somewhat weaker into southern TN, but some threat for
all severe hazards may accompany the northernmost cluster as it
encounters a downstream outflow boundary.
