Valid 170049Z - 170245Z The severe weather threat for Tornado Watch 249 continues. SUMMARY...Severe threat will spread across the remaining southeastern portions of ww249 this evening. Damaging winds, and perhaps a tornado or two, remain the primary risks. DISCUSSION...Large MCS has matured over northern LA/upper TX Coast and is propagating downstream toward the lower MS Valley. Latest radar data suggests an MCV may be forming within the expansive precip shield over the lower Sabine River Valley. This feature is moving east and may contribute to the overall organization of the cluster as it spreads across southern LA. LLJ is forecast to strengthen across southern LA over the next few hours and latest VAD from LCH supports this with 0-3km SRH in excess of 550 m2/s2. Strong low-level warm advection favors a well-organized MCS advancing east and damaging winds remain the greatest risk along the surging bow-like structures. Additionally, some tornado risk continues with embedded supercells along the QLCS. ...Darrow.. 05/17/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!7pxc5wuLtcIRjDz0XnxqI6kci4NBLzewFrOAPcOVHan9z9j18Iy-r186bay8rFMKvM2XZhxvL= PwIDyukfKf_jfj6vcc$ for graphic product...
