This is NOT an atomic bomb cloud or mushroom cloud.
It’s a weather phenomenon called a microburst or downburst, which engulfed downtown Dallas on June 4, 2017.

Microburst is a downward wind (science term downdraft) that brings heavy rain and damaging winds in thunderstorms.
Microbursts form when a storm’s downdraft is so strong that it looks like the clouds are coming down.
What stuff that looks like clouds touching the ground, that’s actually very heavy rain.
It flattens out at the bottom because the wind shifts parallel to the ground.
That’s when the winds shift from vertical to horizontal and do a lot of damage.
At about the same time last year, another apocalyptical microburst swept across Phoenix, Arizona.
