Mesoscale Discussion 2237 NWS Storm Prediction Center Norman OK 1149 PM CST Mon Nov 18 2024 Areas affected...Lower Mississippi Valley Concerning...Severe potential...Watch unlikely Valid 190549Z - 190715Z Probability of Watch Issuance...20 percent SUMMARY...Gusty winds, and perhaps a brief tornado, are possible with convection as it progresses across the lower Mississippi Valley. DISCUSSION...Surface front continues to advance slowly east across LA into western MS late this evening. This boundary is becoming less forced with time as the primary upper trough is lifting north-northeast across western IA. Some semblance of a LLJ persists ahead of the front from southeast LA into MS, and this appears to be aiding frontal convection that is currently concentrated from western MS into southwest LA. Latest radar data suggests some organization to the squall line and a few bow-type structures are evident along the leading edge of convection. Gusty winds, and perhaps some risk for a brief tornado, can be expected with convection as it propagates east into the early morning hours. Current thinking is the severe threat may remain a bit too isolated to warrant a watch, but will continue to monitor the lower MS Valley. ..Darrow/Hart.. 11/19/2024 ...Please see www.spc.noaa.gov for graphic product...
