[html]MD 1953 CONCERNING SEVERE THUNDERSTORM WATCH 637... FOR NORTHEAST LOUISIANA INTO PORTIONS OF WEST-CENTRAL/SOUTHWEST MISSISSIPPI
Mesoscale Discussion 1953
NWS Storm Prediction Center Norman OK
0809 PM CDT Sun Aug 18 2024
Areas affected...Northeast Louisiana into portions of
west-central/southwest Mississippi
Concerning...Severe Thunderstorm Watch 637...
Valid 190109Z - 190315Z
The severe weather threat for Severe Thunderstorm Watch 637
continues.
SUMMARY...Damaging winds are possible with a line of convection
moving south-southeastward into portions of central Mississippi and
northeast Louisiana.
DISCUSSION...An line of convection has organized along outflow from
earlier storms in central/southeast Arkansas. The 00Z observed
sounding from Jackson, MS, showed 2000+ MLCAPE with minimal MLCIN
and 34 kts effective shear. Though some diurnal cooling will occur,
the overall organization of the cold pool should allow strong to
severe storms to continue for another 2-3 hours. Damaging winds will
likely be the main threat given the transition to a linear mode. It
is possible this line of storms could approach the southern edge of
WW 637 before 03Z. Depending on convective trends, this may warrant
an extension in area and/or time of WW 637.
