S​evere thunderstorms and tornadoes are a threat in the South this weekend as a dangerous threat of flooding rain spreads as far north as the Ohio Valley and central Appalachian

Back-to-back storm systems will bring the potential for severe weather and flooding to the South over the next several days. Strong thunderstorms could produce damaging winds, large hail and isolated tornadoes,

A few thunderstorms could be strong to severe in the Central Valley. Best time frame for stronger thunderstorms will be from 10a through 5p Thursday. Although the chance is low, damaging winds, funnel clouds or an isolated tornado cannot be ruled out. pic.twitter.com/uPjbvYBLld

Strong tornadoes are possible across the South as storms pass through the Gulf Coast region. Some locations could see half a foot of rain, worsening flooding.

A plume of moisture from the Gulf will surge across the South through Thursday. A few tornadoes, including the potential for a strong tornado, and damaging wind gusts are possible for areas from Louisiana into western Georgia.
