DISCUSSION...Over the past several hours, training convection has been continually developing along the northern Gulf Coast along a outflow-reinforced marine boundary. Although a consolidated outflow boundary is slowly developing per regional radar imagery, steady influx of high low-level theta-e air off the Gulf should promote further thunderstorm development through the diurnal heating maximum. Weakly veering winds through the lowest 2 km (best sampled by the KMOB VWP) is supporting sufficient low-level helicity for brief mesocyclone development with an attendant tornado risk. This potential has already been realized at least once based on a recent TDS evident across far southeast MS. Until the sea breeze weakens early this evening, strong updrafts with an attendant brief tornado threat may continue to develop on the southern periphery of the marine/outflow boundary. Given the localized nature of the threat watch issuance is not anticipated. ..Moore/Smith.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MOB...JAN...LIX...
