Mesoscale Discussion 0790 NWS Storm Prediction Center Norman OK 0609 PM CDT Sat May 13 2023 Areas affected...Southeast MO...Southern IL Concerning...Severe Thunderstorm Watch 222... Valid 132309Z - 140115Z The severe weather threat for Severe Thunderstorm Watch 222 continues. SUMMARY...Gusty winds remain possible with convection this evening. However, new watch is not currently anticipated. DISCUSSION...Weak low-level warm advection persists across the Midwest into the lower OH Valley early this evening, coincident with a surface front draped from central IN-central IL-central IA. Scattered convection persists along this corridor but updraft intensity has waned over the last few hours amidst neutral/weak height rises aloft. While modest instability resides immediately downstream across southern MO into southern IN, convective trends do not favor organized severe persisting beyond watch expiration time. ..Darrow.. 05/13/2023 ...Please see www.spc.noaa.gov for graphic product...
