The severe weather threat for Severe Thunderstorm Watch 8 continues.
SUMMARY...Severe hail remains possible for the next few hours.
DISCUSSION...Cluster of thunderstorms continues to progress
southeastward along a warm front draped across the region. Several
embedded supercells exists within this thunderstorm cluster along
its southwestern periphery where a moist inflow is being
strengthening by a modest low-level jet. Radar reflectivity is also
showing some hints towards MCV development, which is further
supported by the overall longevity and organization of the system.
Strong vertical shear (i.e. effective bulk shear over 50 kt based on
the latest mesoanalysis) will continue to support rotating updrafts
capable of severe hail. Given recent development farther east, an
areal extension may be needed across portions of east-central MS.
