A fascinating
depiction of what we have all been talking about. Increased helicity, riding along the boundary... from BP's post.

Haha was just about to post that here but yep pretty much what I was talking about earlier today wrt tornado climo & CAD.

Gotta really watch these storms near that mesolow in Spartanburg-Chesnee, especially if they're tracking parallel to the boundary. That's how you can get numerous tornadoes in one area & strong/long-lived ones too.

First off, glad youre alright!!
Normally, I don’t really get nervous over weather but I have a really eerie feeling about this event for us. The winds are gusting. Temps have shot up. And sun is still peaking through.

Is that Concord? Tropical unstable air. Those cumulous clouds are foretelling.
Just had that line pass through and can now see some blue skies starting to emerge.
Sun really trying to break through here in Hillsborough.

Glad you are okay. That was a deep red over Spartanburg.

Timing may save the day for us east of I 95 and prevent the front from tapping into the instability currently present....
Lol that meso low is making any shower that forms ahead get supercellular structure 
Skies got dark but overall “meh”

Areas affected...northern South Carolina into central North Carolina
Concerning...Tornado Watch 41...
Valid 181910Z - 182145Z
The severe weather threat for Tornado Watch 41 continues.
SUMMARY...Storms will continue to develop east/northeast across the
watch area, and a new watch could be needed into central North
Carolina later this afternoon.
DISCUSSION...A broken line of cells continues to progress east into
northwestern SC, near the surface trough and along and north of the
warm front. Surface analysis shows warming and destabilization
continues south of this front, and this should allow these storms to
persist and perhaps expand in coverage. The greatest severe risk
appears to be along the warm front, where storms will experience
enhanced lift. Strong deep-layer shear as well as effective SRH of
200-300 m2/s2 will favor supercells at times, with a threat of a
brief tornado or damaging gusts. If storm trends continue up over
the next few hours, an additional watch could be needed downstream
into NC.

You definitely don't want storms like this near or just after sunset, that's when your tornado threat will tend to be highest as they've had the most time to mature & the low-level jet is intensifying.
I hate that is is so difficult now to get up to date good radar images for local areas.

I'm thinking the counties that lie between I-85 and I-95 will be faced with the most intense conditions, as now until 7 PM would be considered peak heating.

In saying this, the diurnal timing looks pretty close to ideal for tornadoes in places like the Triangle as the storms should be arriving around sunset give or take an hr ish
