Mesoscale Discussion 2209 NWS Storm Prediction Center Norman OK 0505 PM CST Mon Nov 04 2024 Areas affected...northeast Texas...far southeast Oklahoma...southwest Arkansas Concerning...Tornado Watch 704... Valid 042305Z - 050000Z The severe weather threat for Tornado Watch 704 continues. SUMMARY...A tornado threat is likely to persist over northeast Texas, far southeast Oklahoma, and southwest Arkansas this evening. DISCUSSION...Convection within a confluence line beneath the 50 kt low-level jet has gradually strengthened, with supercells now evident. This zone remains in a favorable shear and instability space, with 0-1 SRH over 250 m2/s2 and high surface theta-e values ahead of the cold front. Surface observations also indicate winds gusting over 25 kt, indicative of the coupled boundary layer and expected full incorporation of available low-level shear. As such, a new watch will be needed for parts of the region, with threat persisting until the cold front pushes through. ..Jewell.. 11/04/2024 ...Please see www.spc.noaa.gov for graphic product...
