Valid 211630Z - 221200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS TONIGHT ALONG
THE CENTRAL GULF COAST....

....SUMMARY...
Isolated strong thunderstorms are possible overnight along the
central Gulf Coast region.

....Gulf Coast...
Morning water vapor loop shows an upper low over central KS, with
fast zonal flow across much of the southern tier of states.  At the
surface, the primary baroclinic zone lies offshore of the Gulf Coast
states from south of Houston to near Tampa.  This boundary is
forecast to lift slowly northward today and tonight, approaching the
central Gulf coastline after midnight.  Most models show scattered
showers and thunderstorms in vicinity of the warm front, which may
move ashore late tonight.  Forecast soundings show sufficient deep
layer vertical shear for rotating updrafts and the possibility of a
few strong wind gusts or a tornado.
