Areas affected...Northern/Central Alabama

Concerning...Tornado Watch 722...

Valid 290343Z - 290515Z

The severe weather threat for Tornado Watch 722 continues.

SUMMARY...Severe squall line will propagate across Alabama late this
evening.

DISCUSSION...Severe QLCS is propagating steadily east, in response
to a strongly dynamic trough that is ejecting across the lower MS
Valley. This linear MCS has surged 100-150mi ahead of the synoptic
front, with the leading edge of the squall line now roughly
extending along the AL/MS border. Intense LLJ has aided some
northward destabilization, with lower 60s surface dew points noted
to near the TN/AL border. Damaging winds can be expected with this
MCS, along with some risk for tornadoes, especially with embedded
supercells. This line is expected to advance across the remainder of
ww722 into eastern AL after 07z.
