SPC Mesoscale Discussion: Tornado Watch 58…

| April 14, 2019 @ 5:37 am

SUMMARY…The severe weather threat continues WW 58.

DISCUSSION…A linear complex continues to migrate east-northeastward across western portions of WW 58. Areas of rotation have been observed within individual cells within the band, which isnt surprising given very strong low-level shear indicated in mesoanalyses and VAD wind profiler data from WSR-88D MXX. Instability values also remain around 1000-1500 J/kg MUCAPE owing to upper 60s F dewpoints just ahead of the storms. With a motion of 230/45, these storms should eventually reach eastern portions of the WW around 12-13Z. With a similar environment in place across those areas (with respect to shear/instability), it seems plausible that at least an isolated severe threat will persist as storms eventually approach southwest Georgia and vicinity after about 13Z. The need for a WW will be re-evaluated at that time.
