SPC Mesoscale Discussion: Severe Thunderstorm Watch 44…

| April 7, 2019 @ 9:40 pm

SUMMARY…A dying line of storms will progress east across Mississippi and perhaps into southwest Alabama this evening. While a few strong wind gusts are possible, a watch is not required.

DISCUSSION…A long-lived MCS continues to weaken this evening, with a decrease in trailing STRATIFORM precipitation and a thinning of the leading-edge convection. 00Z soundings into central MS and AL indicate that diurnal cooling of the boundary layer will likely lead to a decrease in storm coverage, both ahead of the line and within, as a capping inversion exists around 700 mb. Instability levels are much weaker into the FL Panhandle region, with nearly zero MLCAPE noted on the TLH sounding. Thus, trends of the last hour are expected to persist.
