I am kinda interested in these storms that are forming east of ATL into SC. Especially going into tonight as conditions will become more favorable for some more rotation.

 

[BufordWX]

@NoSnowATL looks like a quartet of mini supercells are trying to form south of you.

Areas affected...Eastern AL...Western GA

Concerning...Tornado Watch 498...

Valid 102054Z - 102230Z

The severe weather threat for Tornado Watch 498 continues.

SUMMARY...The threat for brief tornadoes will continue into the
early evening as convection spreads slowly eastward.

DISCUSSION...At 2045Z, a band of convection continues across eastern
AL into western GA. Weak rotation has occasionally been noted with
the stronger discrete cells. While instability remains weak across
the region (MLCAPE generally less than 500 J/kg), 0-1 km SRH of
200-400 m2/s2 will support a brief tornado threat with the stronger
convective elements, especially with any discrete elements in closer
proximity to the effective warm frontal zone, where low-level flow
remains backed. Some threat may spread slightly east of the watch
with time, as additional development occurs ahead of the main
convective band. Local watch extension may be needed at some point
depending on the intensity of any new development.

It’s in Loganville heading north towards me. Let’s Go!

Looks like Delta’s tornado threat is gonna turn out to be legit.

Think she will die out but she got close.

 

[BufordWX]

I would watch these storms the next few hours. Strong northward component to them.

Just got this crazy fast rotating low topped supercell earlier, motion was impressive

It's crazy that some of the little storms north of Raleigh are showing a little rotation

Yeah the radars aren’t picking up the low level rotation good today per my observation, that motion almost Made me find a safe spot in my place, I’ll send another video if when it appeared over the trees

Here’s the funnel cloud that was associated with the Gwinnett county storm earlier.

Yeah, not so sure I like this setup going into tonight. Since we weren't supposed to have the possibility of rotating storms until tomorrow. Nighttime spin ups albeit that they are supposed to be brief, weak spin-ups is somewhat concerning. Might be a long night.

 

[BufordWX]

Tornado Watch expanded a little bit.

 

[BufordWX]

These storms are getting there act together.

The one over Newnan right now looks particularly interesting

This little guy headed up toward @metwannabe is interesting
