FOR SOUTHEAST LA AND COASTAL MS Mesoscale Discussion 2299 NWS Storm Prediction Center Norman OK 0938 PM CST Fri Dec 01 2023 Areas affected...Southeast LA and coastal MS Concerning...Tornado Watch 713... Valid 020338Z - 020445Z The severe weather threat for Tornado Watch 713 continues. SUMMARY...The threat for a tornadic supercell or two should increase over the next couple hours across southeast LA, including the New Orleans metro area. DISCUSSION...Long-lived convective cluster across south-central LA will likely continue east-northeast into the early morning hours across southeast LA and coastal MS. An embedded supercell has recently intensified over the Assumption Parish vicinity, and additional supercell development will be possible to the southwest of this storm amid strong mid to upper-level speed shear. Low-level hodographs are also in the process of enlarging, albeit from initially small curvature, and should continue to do so for the next several hours. Time-series of the TMSY wind profile confirms 0-3 km SRH has steadily held above 250 m2/s2 and a longer-lived supercell may evolve out of the Assumption Parish storm as it approaches the greater New Orleans/Lake Pontchartrain area through midnight. ..Grams.. 12/02/2023 ...Please see www.spc.noaa.gov for graphic product...
