No severe thunderstorms are expected across the continental United States this evening through tonight. ...DISCUSSION... An upper-level trough will move southeastward across the central Plains, Upper Midwest and Great Lakes region this evening. Scattered thunderstorms will be possible ahead of the trough across parts of the central Great Lakes region due to steep mid-level lapse rates and strong large-scale ascent. Isolated to scattered elevated thunderstorms will also be possible tonight in a warm advection regime across the southern Plains. Instability will remain weak in both the north-central states and southern Plains. For this reason, no severe weather is expected across the continental United States this evening or tonight. ..Broyles.. 11/03/2021 Read more LIVE:
