Mesoscale Discussion 1281

Areas affected...portions of southeast Louisiana

Concerning...Severe potential...Watch unlikely=20

Valid 261618Z - 261715Z

Probability of Watch Issuance...5 percent

SUMMARY...A damaging gust may accompany a line of storms before they
move offshore. A Severe Thunderstorm Watch issuance is unlikely.

DISCUSSION...The remnants of an MCS continue to propagate
southeastward amid a weakly forced/sheared airmass. A slowly
diminishing cold pool is the forward propagation mechanism. However,
the airmass ahead of the storms has warmed to over 90F amid upper
70s F dewpoints, contributing to a very buoyant boundary layer (i.e.
4000+ j/kg SBCAPE/MUCAPE). As such, some of the cells along the
leading line of the diminishing MCS may pulse in intensity to the
point of supporting water loaded downdrafts that may produce a
damaging gust or two. Since the threat for severe gusts should be
very isolated, a Severe Thunderstorm Watch issuance is not expected.
