Several Zones of Severe Weather Tuesday

Tuesday will bring the potential for severe thunderstorms to several regions of the country, as depicted on the top map on the right. There is a possibility for a few tornadoes in the High Plains, but otherwise the primary threats will be damaging winds and large hail.
In addition, there will be the potential for flash flooding from heavy downpours, particularly across the central and southern Appalachians. This includes places such as Knoxville and Atlanta.
