Concerning...Tornado Watch 28...29...
Valid 250412Z - 250545Z
The severe weather threat for Tornado Watch 28, 29 continues.
SUMMARY...Squall line will continue surging east along the central
DISCUSSION...Surface dew points are gradually rising along the
central Gulf Coast this evening with mid 60s now evident ahead of
the squall line into southeast LA. This air mass should advance
inland, just ahead of the convection, across southern MS/AL/western
FL Panhandle. Most robust storms are occurring where greater
buoyancy is noted and this should continue into the early-morning
hours. Strongly-forced squall line will surge east of ww0028 in the
next hour or so before spreading into western portions of ww0029. In
addition, isolated showers/supercells continue to develop ahead of
this line within the warm advection zone, and this activity will
likely continue to generate over the northern Gulf, then spread
inland as the overall complex shifts east.
