NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected across the continental U.S. tonight.
Synopsis
A baroclinic zone across the Southeast U.S. continues to sag southward as a broader upper trough tracks eastward from the Great Lakes. Given the lack of stronger upper air support and the onset of nocturnal cooling/decreased buoyancy, the coverage of lightning flashes across the Southeast should continue to decrease overnight. Similarly, a plume of marginal buoyancy over CO into NM, which has supported some lightning flashes thus far, should also wane through the evening.
