SPC Mesoscale Discussion: Tornado Watch 55…

| April 13, 2019 @ 9:13 pm

SUMMARY…The severe weather threat continues across tornado watch 55. The primary threat will likely be damaging winds into the overnight hours.

DISCUSSION…The cold front is currently surging across Mississippi and has started to catch the pre frontal convection in north central Mississippi. As this front continues to move eastward, bowing line segments may become increasingly likely with the threat for damaging winds. Given the strong low-level helicity across the area (greater than 500 m2/s2 per HTX VWP), embedded QLCS tornadoes are possible. The warm front may lift a few counties north in the next few hours to the northern most row of counties in Alabama. The greatest damaging wind threat will be anywhere south of this warm front with the tornado threat maximized in close proximity to this warm front where low-level flow will be more backed.
