SPC Mesoscale Discussion: Tornado Watch 369…

| September 4, 2018 @ 10:24 pm

SUMMARY…The tornado threat continues across WW 369.

DISCUSSION…Tropical Storm Gordon continues its northwestward trek, with landfall near the Mississippi/Alabama border. Low-level flow east of the center of Gordon has veered slightly to an east-southeast direction, allowing for a slightly more unstable airmass (characterized by 73-75F dewpoints and 1000-1500 J/kg MUCAPE) to advect inland especially near coastal areas. This has coincided with a recent uptick in convection across portions of Baldwin (AL), Escambia (FL), and Santa Rosa (FL) counties. Abundant low-level shear has fostered occasional, yet transient rotation in a few of the cells, and a tornado was observed near NSE in the past half hour. Much of the tornado threat will be concentrated in this region in the near-term, and this threat may continue to advance farther inland/northwestward to include Mobile County, AL over the next 1-2 hours as well.
