MD 0303 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR THE NORTHERN GULF COAST

Mesoscale Discussion 0303
NWS Storm Prediction Center Norman OK
0209 PM CDT Sun Mar 30 2025

Areas affected...The northern Gulf Coast

Concerning...Severe potential...Watch unlikely 

Valid 301909Z - 302115Z

Probability of Watch Issuance...20 percent

SUMMARY...The potential for brief tornadoes may continue through the
late afternoon.

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.
