Areas affected...portions of eastern Mississippi and southern
Alabama

Concerning...Severe potential...Watch possible=20

Valid 242152Z - 242245Z

Probability of Watch Issuance...40 percent

SUMMARY...Severe threat may continue downstream of WW317.

DISCUSSION...Ahead of an ongoing line of thunderstorms across
south-central Mississippi, new thunderstorms development has been
ongoing and intensifying along southeastward moving outflow. A few
instances of severe hail around 1" have occurred with this activity.


There is some uncertainty on maintenance of the main line of storms
downstream of WW317. This line is moving southeastward and away from
the better flow aloft to the north, thus better forcing and shear
for organization. In addition, outflow has moved out ahead of the
southern portion of this line over the last hour. The air mass ahead
of the line across southeastern MS into southern AL remains hot and
unstable, with MLCAPE around 2500 J/kg. Should the northern portion
of the line be able maintain an organized cold pool, the downstream
wind threat may continue into the evening across central/southern
Alabama and a new watch may be warranted to cover this risk. Recent
CAM guidance suggests the line may weaken as it moves into southern
Alabama. As such, watch issuance remains uncertain but this area
will be monitored for downstream threat.
