A strong storm system that's produced large hail, damaging wind and even a few tornadoes over the past two days is headed through the Carolinas later today. Although it will be in a weaker state, it will still be capable of producing strong to severe storms.
The cold front associated with this system will sweep through the Carolinas and produce a line of storms that will move through between 5pm and midnight. There could also be a few showers and storms that pop up ahead of the main line that will need to be watched as well.
With enough sunshine, the atmosphere will become increasingly unstable this afternoon. Additionally, the wind shear will be sufficiently high enough so any thunderstorms will be capable of producing damaging winds in excess of 58 mph.
The overall risk of damaging winds is 15%. In other words, there is a 15% chance of damaging straight-line winds within 25 miles of a given point. The tornado risk is lower, but not zero. The chance of a tornado touching down within 25 miles of a given point is 5%.
The cold front will move off the coast late tonight, but moisture lingers so some rain is likely into early Saturday morning. By mid-morning, rain moves away followed by clearing skies in the afternoon.
It will be much cooler this weekend as well with high temperatures in the 60s.
