Black heralded in the storm--"black" is not a word you can get away with JUST to create atmosphere. It is way too common. The meter is also indistinct because the emphasis is forced on to the opening SINGLE syllable so giving the rest of the line no option but to mis-step. You may be forced to think around it. Try "Hoo/ded dark/ness led/the storm;"
Low minacious clouds argued"Minacious clouds with low intent,
thumping chests and roaring argued; roaring, thumping chests.
Throaty obscenities flew Obscenities in throaty flight,
within cumulonimbus. cumulonimbus wrapped,
just two seconds after blue two seconds after blue
or something. The rhythm is now set away.

Kids swam streets, oblivious the streets
power lines lay limp. Unlit Now over to you....or just say fuck you.
tipper trucks ploughed the water,
loaded to the gunnel's, highgunnels not possesive. "gunnels" is plural
enough for human debris
to be carried from their roofs.

Once, it cleared and lightness sprang. Yippee! The meter matches the modified line one!
floods grew weak and settled down,
people cheered, defences down.down and down
All too soon the laughter died:
Anger raced across the sky
then dropped like rods of iron.two cliches, two lines, too much

Again it rained....but a good commitment-verse ending. This is where it was always going. I like

Stirring stuff, billy. Some concern over the poetic endeavour versus pedantic correctness, but that's what you would expect that I would expect. My in-text comments are what I would do, but in this image-rich stuff you may choose to ignore all rules ( no comments on the "rules" please. I have heard them all before) .
Meter. Let others help. Though it is just as important to me as it seems to be to you I am sick of my own voice!
Good effort at this reality verse. A lot has ben written in the genre and it is difficult to say anything new. You did well.
Best,
