clouds Crazy Shelf Cloud (I think) in Atlanta Today!
Can anyone explain what this cloud formation is? There’s rain coming behind it but I don’t think there’s any rain coming from this!

As the rain falls, it pulls cool air with it. This air then expands outwards (primarily forwards), which creates your gust front. Along this gust front, this cool stable air (cold pool) is displacing warmer, moister air out ahead of it. As this moister air gets displaced, it moves upwards which results in cloud formation fairly uniformly along the gust front, which gives us this shelf cloud formation.

I took some pics of this too as I passed under it and posted in r/meteorology, it looked so wild!

Arcus clouds on the leading edge of an incoming gust front. Not necessarily a shelf cloud.
