DISCUSSION...Large complex of storms has evolved within a warm-advection regime from east of Detroit, southeast across eastern Ohio into northern WV. This activity continues to expand in areal coverage which is reinforcing a surface boundary that currently extends from south of CKB-PKB-MFD-west of DTX. This activity is elevated atop a cooler, rain-cooled air mass over the upper OH Valley, but sustained westerly LLJ should continue to generate new updrafts over southeast lower MI into the western parts of Lake Erie. This activity should gradually propagate into a less favorable environment near the OH River, where low-level warm advection should remain somewhat weaker through the night. Even so, steep mid-level lapse rates (greater than 7 C/km) will continue to spread into the back side of this slow-moving MCS such that fresh updrafts are expected along the northwestern flank. The most robust updrafts could generate hail near one inch and gusty winds may accompany the leading edge of the MCS. Otherwise, heavy rain appears to be the primary risk with this activity, and unless unexpected intensification occurs, severe thunderstorm watch is not currently expected. ...Darrow/Hart.. 08/24/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!9VX0b94oEnQ-QJZKv-5FFel2AI4ZQluvOUoZu28VkyUzWP5ZLu4c8UKbMKOlTSRPwk2G2KzJX= mcxW3jbBLLNZcxXUeo$ for graphic product...
