This month's Unearthed Arcana is a comparative breath of fresh air.
Giving rules options for Minotaurs (who get a 1d10 weapon in their horns which they can bonus-attack Shove with at level 1, constant advantage in all Shove actions, plus a charge attack), a Duelist Rogue (who gets to sneak attack anybody who is NOT adjacent to his allies, in an attempt to encourage 1 on 1 duels), and a Storm archetype sorcerer. I'll come back to the sorcerer in a minute.
This article also revealed the existence of "class ribbons," features given to a class solely for flavor and which are not evaluated by the designers when considering combat performance or class balance. They say, for example, Thieves Cant is a ribbon. It might give an occasional out-of-combat advantage, but when considered as a whole it's a footnote at best that might come up once or twice in a campaign.
Then they go on to elaborate that the Storm Guide feature of the Storm Sorcerer is intended to be such a ribbon.
" Storm Guide
At 6th level, you gain the ability to subtly control the weather around you.
If it is raining, you can use an action to cause the rain to stop falling in a 20‐foot radius centered on you. You can end this effect as a bonus action.
If it is windy, you can use a bonus action each round to choose the direction that the wind blows in a 100‐foot radius around you. The wind blows in that direction until the end of your next turn. You have no ability to alter the speed of the wind."
Now, I think about all the cloud / mist / fog spells in the game. And then I look at the storm sorcerer's level 1 ability:
"Tempestuous Magic
At 1st level, you are attuned to elemental air magic. Whenever you cast a spell other than a cantrip during your turn, whirling gusts of elemental air surround you. You can use a bonus action to fly 10 feet without provoking opportunity attacks."
So yes, every round you cast a non-cantrip spell, I think there's a pretty strong argument to be made that you can take a bonus action and drastically affect any cloud/fog effects nearby.
Anyway, if you want to take a gander yourself, here's a direct link to the PDF
