MD 2226 CONCERNING TORNADO WATCH 639… FOR NORTHERN/CENTRAL LOUISIANA AND WESTERN MISSISSIPPI
Mesoscale Discussion 2226 NWS Storm Prediction Center Norman OK 0922 PM CST Mon Nov 24 2025 Areas affected...Northern/Central Louisiana and western Mississippi Concerning...Tornado Watch 639... Valid 250322Z - 250515Z The severe weather threat for Tornado Watch 639 continues. SUMMARY...Severe threat is expected to spread across northern, and portions of central, Louisiana over the next 1-3 hours. With time this activity should spread into western Mississippi. DISCUSSION...Low-amplitude short-wave trough is approaching the lower Sabine River Valley, per latest water-vapor imagery. In response to this feature, a squall line has matured over the last few hours, extending from San Augustine County TX-Bienville Parish LA. Along this corridor, several smaller bow-like structures have developed and have accelerated a bit in response to strengthening midlevel flow. This linear MCS is expected to advance across the remainder of northern/central LA by 06-07z, likely spreading into portions of western MS as the warm front gradually lifts north. There is some concern this activity may remain organized as it exits the northeastern corner of ww639. If air mass destabilization is adequate downstream, a new watch may be warranted. Tornado risk continues with any supercells, and with circulations along the squall line. Localized damaging winds may also be noted ahead of any fast-moving bow echoes. ..Darrow.. 11/25/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JAN...LCH...SHV...
