An outbreak of intense thunderstorms is expected across portions of the South US over the next few days. Heavy rainfalls, strong winds, and several tornadoes are possible.
The thunderstorms will be fueled by the abundant moisture coming from the Gulf of Mexico, combined with a cold front and jet stream.
Intense storms were already reported in the south-central Nebraska on November 27, 2016, and east of Durant, Oklahoma on November 28. Four short-lived tornadoes were observed in Nebraska, although no damage occurred. A damaged building and several downed trees were reported in Oklahoma.
