SPC Mesoscale Discussion: Severe Threat Continues

| April 14, 2019 @ 4:21 am

SUMMARY…The threat for tornadoes and wind damage continues for WW 57. A new tornado watch may eventually be needed downstream after 1030-1100Z.

DISCUSSION…A broken band of convection continues near the I-65 corridor from middle Tennessee into central Alabama currently. A few of these storms have exhibited signatures consistent with brief tornadoes – most recently in Shelby County near BMX. These storms continue in a strongly sheared, yet weakly unstable environment, with enough instability present to maintain the severe threat through the eastern extent of WW 57. An estimated 230/45 storm motion should take these storms toward the eastern end of the WW around 11Z or so, and a downstream tornado watch issuance will probably be needed.
