ZCZC SPCSWOMCD ALL ACUS11 KWNS 171254 SPC MCD 171254 LAZ000-171500- Mesoscale Discussion 0269 NWS Storm Prediction Center Norman OK 0754 AM CDT Sun Mar 17 2024 Areas affected...Parts of the LA Gulf Coast Concerning...Severe potential...Watch unlikely Valid 171254Z - 171500Z Probability of Watch Issuance...20 percent SUMMARY...Some threat for isolated damaging gusts and perhaps some hail may develop this morning. DISCUSSION...Widespread convection is ongoing this morning across the northeast Gulf of Mexico and adjacent portions of the LA and upper TX coasts, in association with a convectively enhanced shortwave trough. Continued upscale growth into an eastward-moving MCS is possible with time, as convection moves near/north of a baroclinic zone draped across the northern Gulf of Mexico. With the accompanying MCV expected to track near the coast, some threat for locally damaging gusts may evolve slightly inland if an organized MCS does develop. Otherwise, moderate elevated buoyancy could support an isolated hail threat within the warm-advection wing of the MCS across far southern LA. With the inland threat expected to remain generally limited in areal coverage and magnitude, watch issuance is currently considered unlikely. ..Dean/Thompson.. 03/17/2024 ...Please see www.spc.noaa.gov for graphic product...
