A few strong thunderstorms capable of gusty/damaging wind gusts may occur this afternoon in southwest Lower Michigan. ....Southwest Lower MI... Morning water vapor imagery shows a deepening upper trough over the upper midwest digging into the western Great Lakes. This trough and its associated surface cold front will move across southern Lake Michigan this afternoon during the peak-heating period. Strong heating ahead of the front is leading to steep low-level lapse rates. CAPE values will be weak (less than 500 J/kg). However, given the favorable timing of the system, strong winds aloft, and steep low-level lapse rates, it appears possible that a few strong/severe wind gusts could occur with showers/thunderstorms along the coast of southwest Lower MI. Therefore have added a small MRGL risk area for this scenario. Cold temperatures aloft and ambient vorticity near the upper trough could also result in isolated waterspouts in this area. ...Hart/Moore.. 10/06/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
