A storm system moving through the Lower Mississippi Valley will curve northward toward the Appalachians today (Friday), bringing a threat for severe thunderstorms. There is a marginal risk (level 1 on a scale from 1 to 5) for the Florida Panhandle for the first half of the day, and in eastern North and South Carolina later this evening and night.

Strong wind gusts and isolated tornadoes are the main severe weather threats. Increasing humidity from the Gulf of Mexico, robust jet stream energy, and moderate instability will support severe thunderstorm development.

The storm will curve northward throughout the day, bringing heat, humidity and instability. This will lead to additional thunderstorm developing for tonight and again, some severe.
