Mesoscale Discussion 0411 NWS Storm Prediction Center Norman OK 0535 AM CDT Wed Apr 10 2024 Areas affected...Far Southeast TX...Southern LA...Central/Southern MS Concerning...Tornado Watch 100... Valid 101035Z - 101230Z The severe weather threat for Tornado Watch 100 continues. SUMMARY...Strong wind gusts and line-embedded tornadoes remain possible across far southeast Texas and southwest Louisiana. Additionally, the tornado threat appears to be increasing across southeast Louisiana and southern Mississippi, where a Tornado Watch will be needed soon DISCUSSION...Ongoing convective line continues to move quickly across far southeast TX. Recent radar imagery has shown an increase in echo tops within the line, with a bookend vortex also becoming more observable. This line is now more favorably oriented with the deep-layer vertical shear vector and the downstream air mass remains moist and unstable. As such, the line is expected to continue progresses eastward into southwest LA, with some potential intensification possible. Primary threat remains strong gusts (60-80 mph), but embedded QLCS tornadoes are possible as well. Farther east, a blossoming warm-air advection regime is contributing to increasing storm coverage and intensity. Storm in Assumption Parish has a strong updraft with modest supercellular characteristics. This trend for increasing storm coverage and intensity will likely spread northward/northeastward into more of southeast LA and eventually into southern MS. The parameter space supports supercells capable of all severe hazards and Tornado Watch will likely be needed soon. ..Mosier/Smith.. 04/10/2024 ...Please see www.spc.noaa.gov for graphic product...
