SPC Mesoscale Discussion: Tornado Watch 419…

A tornado threat remains possible through 11-12Z across southeast Louisiana into southern Mississippi with discrete storms, ahead of the primary line of storms. Meanwhile, the eastward-moving line of storms will continue through an environment conducive for damaging winds and a tornado threat.
