Mesoscale Discussion 0807 NWS Storm Prediction Center Norman OK 0531 PM CDT Thu May 16 2024 Areas affected...Lower Mississippi Valley Concerning...Severe potential...Watch possible Valid 162231Z - 170030Z Probability of Watch Issuance...40 percent SUMMARY...Severe threat is expected to gradually increase across the lower MS Valley this evening. There is some consideration for a new watch across this region later this evening. DISCUSSION...Sustained low-level warm advection is focused across the lower MS Valley early this evening. An expansive MCS has evolved across east TX/northern LA and the leading edge of this activity is slowly sagging south, but spreading/developing east of ww249. Later this evening, LLJ is forecast to increase markedly across the northwestern Gulf Basin into LA, and this will encourage convective overturning of a very moist/buoyant air mass south of the MCS. Marginally severe hail is possible with this activity but damaging winds may be the primary risk, especially if line segments are able to evolve. ..Darrow/Smith.. 05/16/2024 ...Please see www.spc.noaa.gov for graphic product...
