FOR PORTIONS OF CENTRAL AND EASTERN LOUISIANA Mesoscale Discussion 2277 NWS Storm Prediction Center Norman OK 0523 PM CST Mon Nov 20 2023 Areas affected...portions of central and eastern Louisiana Concerning...Tornado Watch 711... Valid 202323Z - 210100Z The severe weather threat for Tornado Watch 711 continues. SUMMARY...Ongoing severe storms will continue to pose a risk for a few tornadoes across WW711 this evening. DISCUSSION...Across parts of central LA, a band of convection has shown slow maturation with a couple of supercells becoming established from the broader convection over the last couple of hour. Ongoing within a moist, and unstable environment, conditions look favorable for these storms to maintain intensity this evening. Strong mid and upper-level shear will continue to favor organized storms including supercells and short line segments. While surface winds have veered slightly this afternoon, low-level hodographs remain long and supportive of strong low-level mesocyclones. Low-level shear should increase to the east beneath a southwesterly low-level jet. As storms mature they should remain capable of a few tornadoes and damaging gusts across central and eastern LA this evening. ..Lyons.. 11/20/2023 ...Please see www.spc.noaa.gov for graphic product...
