Our peaks of sun this afternoon have led to a bit more of an unstable atmosphere, which is leading to the scattered showers turning into thundershowers. Nothing is severe and nothing is expected to be severe. Just be aware that there is some lightning out there. You folks at the Cumberland County Fair need to especially be mindful of any lightning in the area.
You can also tell the activity it getting an extra kick from moving up the plateau.
Below is the current radar, showing scattered showers and thundershowers moving in from the west.
