I said one forecaster because there was only one guy giving the severe weather briefing when they put out that graphic.
But you're correct, I should have said earlier *forecasting crew*

Wow hrrr... it’s the LR hrrr and tends to over do sum things but this looks quite similar to the NAM

Hrrr also shows a large hail threat with solid VILs, strongest updrafts could have some big hail even with CAPE somewhat low due to the amount of shear around 6km

Much larger portion of NC in the level 3 zone now. Don't like seeing that at all. Wonder if it could be upgraded tomorrow to a level 4.
(I refuse to say the name of the categories anymore because they don't make sense.)
Tornado warned supercell in Texas has two different rotations right now.

The wording is no good either. Essentially going with the worse of the 2 scenarios. SRH levels are extreme as he puts it. Any supercell is gonna rotate and we could be in for a tornado outbreak.

Pivotal weather is free. Take a look.

CIPS slowed down now splitting this system over 2 days opposed to one day the last few runs showed. Here the updated CIPS

The key for the Carolinas tomorrow:
The main question with this outlook is convective mode. There are
two possibilities. The first is that the band of thunderstorms will
have discrete elements and gaps that will be favorable for
supercells and tornadoes. Forecast soundings at 15Z from southern
Virginia southward into northern South Carolina show looped
hodographs with 0-3 km storm relative helicities in the extreme
catogory, generally near or above 600 m2/s2. This would support a
threat for strong tornadoes associated with the more dominant
supercells. A wind damage and hail threat would be likely with
supercells and with the more organized line segments.
The second scenario would be that a squall-line is ongoing at 12Z
from eastern Georgia northward into the western Carolinas and
Virginia. In that case, widespread wind damage would be likely. A
QLCS tornado threat would exist with the stronger bowing line
segments. Hail would also be possible with the more intense parts of
the line.
The questions is which one will it be?

I dont like the fact they seem to lean towards scenario #1

One thing worth noting so far is the way precipitation seem to be evolving with the warm front. It appears to be light and scattered. Also note the lack of precipitation over middle and southern Mississippi. If these two factors hold that would not be good for later
Tornado watch expanded
Can’t recall a briefing this concerning in central NC
Here’s GSP they aren’t as concerned about tornados as RAH but do mention we could see a strong long track tornado along or south of 85.

HRRR has backed off on the potential convection along the warm from late this afternoon, mainly because mousture return isn't as aggressive as previoisly projected (thus a stronger cap).

In the nw upstate sc area I’m not to worried. As I believe it will be weakening as it’s moving in. Doesn’t mean there won’t be a isolated tornado. But I’ve seen this time and time again. It will be weakening as it’s moving in. And probably restrengthen in the Eastern upstate
