A strong cold front will be moving into the Carolina Friday afternoon. There will be plenty of moisture and heat for this front to feed off of. The only really question is how much of the strong dynamics will be left for severe storms.
Severe Weather Outlook:
The timing looks to be around 3-6pm. Which is ideal timing during the heating of day for storm to develop. I expect to see a dying squall line early in the morning entering the mountains. Then as it crossing over the mountains by mid-day the storms will start to flare back up in the heating of the day.
There should be plenty of CAPE or thunderstorm fuel for the storm to feed off of.
The squall line nature of the storms should make the primary concern straight line winds of 50-60 mph or higher. There could be some small hail as well. The speed of the storms will prevent much of a flood threat and while the tornado threat is not zero it is low right now. The only thing that could make the tornado threat increase would be isolated cells ahead of the main line. Or interaction with previous days outflow boundaries and sea breeze closer to the coast.
