Im a little disappointed the upstate of South Carolina hasnt gotten in on much action. Hopefully that will change in a couple hours

as the line bends and drops due south, now going on, from Tenn, then the southwest most part of the line will clip SC and ne GA most likely. Give it a few hours yet, you're not out of the woods. Often times, the southwest flank of systems dropping over a ridge , and the mountains, will be most severe in that location.

like always, any and all severe weather cells are at peak around South Mountains. Gotta get me a house up there soon. I think some on here are confused about how this plays out and are being fooled by the radar. The White lines are how the motions have been earlier and now, but soon, the second part of the system will begin to dive southward. Don't let your guard down really anywhere in eastern TN , n. GA and the Carolinas, just b/c radar may be pathetic where you are now. Its a fast changing system and SPC has good reasoning why the watches are placed. The southwest most part of any line like this is usually the place where the isolated twisters are, and are great thunderstorms.

thats encouraging! radar looks pretty feeble for a lot of us...a big storm missed mby by about a county :(

WHOO! Just had a fantastic hail storm with 1+ inch hail falling, some terrific CG lightning, and boomer-style thunder!! Wind kicked up to about 50-55mph at peak gust. :thumbsup:

sweet! :guitar: (although i can generally do with out the hail, i dont want my car dinged up lol)

edited to add:

ps some of these hail reports are astounding. we dont usually get the monster size ones

pps as soon as hit post on the original thread, a huge clap of thunder and the house shook. nothing on radar so i went out and dont really see anything to speak off. sort of odd :unsure:

Warning might be just south of Carowinds...Barely....but they'll get hit hard (looked harder at the polygon)

Looks nasty. Wife has her phone off which is not unusual when she is working. Just have to wait. When she left this morning at 6:30 she asked me what the weather was gong to be. I told her highs somewhere from the 60s to the 80s, sunny, cloudy, showers, chance of severe with hail, tornadoes. She told me to shut up and go back to sleep. This will teach her.

I was told from my dad that a few of these hailstones had a geometric shape to them, some of which were star shaped. Anyone else seen such? Anyway...Skies have lightened up a good bit here but torrential heavy rain fell during the time that it did. Sitting at 58°after reaching 76° for a high today.
