Areas affected...central Gulf Coast

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

Valid 271308Z - 271415Z

Probability of Watch Issuance...5 percent

SUMMARY...A low-probability, brief tornado risk may persist through
the rest of mid-morning across southeast Mississippi.

DISCUSSION...A confluent band of mainly discrete convection has
persisted over the past couple hours, generally perpendicular to a
northwest/southeast-oriented warm front that is roughly approaching
a PIB to MOB line. Transient supercell structures have been noted,
and these may persist through about 15Z. The 12Z LIX RAOB sampled a
bit of near-surface stability, but otherwise contained a
conditionally favorable buoyancy/shear space for a supercell
tornado. As noted in the 13Z SWODY1, the background synoptic
environment is unlikely to support substantially greater
organization. In conjunction, with further waning of large-scale
ascent, overall tornado potential in this area should be brief and
temporally diminish by late morning.
