Mesoscale Discussion 2236 NWS Storm Prediction Center Norman OK 0609 PM CST Mon Nov 18 2024 Areas affected...Southeast TX...Central LA Concerning...Tornado Watch 711... Valid 190009Z - 190145Z The severe weather threat for Tornado Watch 711 continues. SUMMARY...Scattered supercells will continue spreading northeast across the eastern half of ww711. DISCUSSION...Several long-lived supercells are noted within ww711 early this evening. One in particular is crossing Newton County TX into northwestern Vernon Parish. This activity appears partly aided by the right-entrance region of the mid-level jet, along with sustained low-level warm advection. While lapse rates are not that steep, low-mid 70s surface dew points are contributing to significant buoyancy. Until the LLJ lifts north of this air mass, organized supercell threat will likely continue. Primary risk continues to be damaging winds along with some tornado risk, especially for the next few hours. ..Darrow.. 11/19/2024 ...Please see www.spc.noaa.gov for graphic product...
