Noting a lot of overshooting top development on the supercells across the northern portion of the Jacksonville CWA as well as into neighboring Charleston, SC’s CWA.  The overshooting top (OT) algorithm picked up two supercells across Long and Bryan counties in SC at 2030 UTC.  With the current sun angle, you can see the Long county top, but not so much on the Bryan one, but the OT tool show them both well.

We can also use the OT tool anytime, day or night, as it is based off the IR satellite data.
