As long as you can cast 8th level spells, yes.

thx. bye bye lazhaar.

I just want to make sure I understand. You can keep changing the weather up or down by one for the whole 8 hours right? You just have to wait 1d4+10 minutes for it to actually change each time?

 Yes, that is correct. this means that you can choose 6, 5, 5, and then fluctuate from 6 to 1 and back to 6 repeatedly in order to not only flood and destroy any place in a 5 mile sphere, but also freeze it with temperatures as low as, or even lower than −58 °F (−50 °C ). So you can soak a populace with flood waters, then freeze them with -58 degree temps and guarantee them dead within 10 minutes or less. And you can repeat this for as long as 8 hours.

And the entire time have them dealing with torrential rain, hail, blizzards, and 60 mph (96 kph) winds.

And via the wording on the spell, i believe that you can change precipitation, temperature, and wind independently of each other.

 they are independent of each others yes, but you choose 3 of them at a time, each time you change the wheater you affect all 3 at the same time. choosing to either go up by one or go down by one. but you can decide not to change one of the three or two of the three and change them all independently.

thus... someone could go to the extremes easily during that time. they probably even could go back to normal day if they wanted to.

When you cast the spell, you change the current weather conditions, which are determined by the DM based on the climate and season. You can change precipitation, temperature, and wind. It takes 1d4 × 10 minutes for the new conditions to take effect. Once they do so, you can change the conditions again. When the spell ends, the weather gradually returns to normal.

When you change the weather conditions, find a current condition on the following tables and change its stage by one, up or down. When changing the wind, you can change its direction.

conditions is plural, meaning more then 1. they are enumerating conditions and using AND, not Or... thus you affect all of them at once everytimes you want to change the weather. but you are not forced to change one condition of the three. so every time you change the weather, you tell it in this order... temperature up, down or stay, then you tell the wind up, down or stay, then you tell temperature up, down or stay ? and thats one change. once they are changed, you can ask the three questions again for another 1d4 multiplied by 10 minutes.

Quote from RodTheBard >>

So... has anyone actually used this spell in play? What did you do, and how did it work out?

 one of my player did, to destroy the city of a bbeg... he thought he was so cool...
bbeg saw the temperature change, casted scrying on the source of the control weather spell. saw the man, teleported to him, cast desintegrate on him. he failed his concentration check and almost vanished, the city was still up and running no problem... by the way that was after the first 3 hours, so he had time to bring the storm. which was too fast to be natural.

another instance of the control weather that hapenned... a wizard friend wanted fog to camouflage his troops... they got into the city thanks to mist and fog. came to the castle in secret... clerics and paladins of the place were ready cause they knew the fog was unnatural in a place where there is barely any fog ever. some of the cleric of knowledge were detecting magic, saw the guy pass before them, dispelled the magic and the temperature was back to normal after a while. but the fight broke out real fast though...

its quite easy to figure that out so those who say ruin a city with ease... well if your DM isn't good enough to use levels for his baddies or think that not only the players can be level 20... then its his fault for letting players be gods in his world. my world is full of high level eople who, like the adventurers travelled one day and made some adventures... how do you think the world got shaped the way it is now ? that's also because of all that magic bullshit that my big capital cities, which are few and wide... have anti magic defenses or high level people taking the time to put enchantments for protections everywhere. prisons with anti-magic fields... checked ! clerics identifying and speaking with the dead to find murderers, checked ! generals actually scrying on other generals and soldiers to find weak spots in other countries, checked ! there is a whole war of attrition when magic is involved. if your world isn't build to contain your players, then nothing will really and they will have it easy. that's why people think high level game sucks, because they think it just breaks the game...

fun fact, it doesn't.. because if the players can do it, then why can't the rest of the world ?
the only magics that ruins the world are few, but do exists... true polymoprh is one, go to the beach make a human sized sand figure, change it into another me. do the same every day. each one of the clones do the same, it creates exponentially... you live in the north... do it with snow and it cost a level 4 instead of 8th. but aside from those, the rest are pretty easy to come by. and if people respect the materials instead of just hand waving them... things gets even more balanced... your player cast identify on your item, does he have the 100gp pearl on him ? you'd be surprised how much players scramble to find the actual components afterwards...

EDIT:
fun little story...
my players ask the king if he wants them to go to the other country and kidnap the child so they can ask a ransom. the king says no. he dislikes such methods, they discuss the actual strategies... after about 30 minutes one of the players ask me, why are you texting on your phone like that... i answered, explaining to the king in person what you are asking and what he would be answering. so i can have a basic idea of how he manage his kingdom. my players all opens their mouth in disbelief ! another one of the player says "thats not for real, you are joking right, you mean to tell us that we are in front of another player ?!!" and i simpyl answered, yup. previous campaign that ended before yours... the player ended up retaking his long lost throne, his character is now 30 years older though, he's in his mid 40ies now. been king for the last 20 or so years. my players said, **** it we're not interracting with another player he will kill us.... and i said, why would he kill assets ? he has a kingdom to run now, he has no quarrel with you guys, on the contrary.... and i turn my phone around ! "i'll pay them 500gold piece each if they bring me the head of the damn guard captain who owes the country because he fled" all the players were mind blown and now wanted to meet the guy in person. i said he can't unfortunately, thats why i'm texting him instead...

my world is alive, other adventurers literally inhabit the world they live in, so yes at some point they might end up meeting other ancient adventurers.
when that campaign will be over, their legacy will start. the other group might see the result of that labor they did previous campaign. now my players are all afraid they might just meet other players just by walking the streets of the cities they are in. but thats the point... there are other high level NPCs in the world !

So when the spell ends, does the weather snap back to normal, or gradually shift?

Could I recast after the 8 hours are up and only need to make 1 or 2 adjustments to be back where I was? Or would I be back at square 1?

So every time someone tried to use this spell you basically said “nope, they sense it and kill you”? That seems lame...

Also pretty sure you can’t uses Scrying to target a unknown caster of a spell. Most people don’t fill their worlds with level 20 adventures because then the player’s don’t feel as special, everything would probably get destroyed by 9th level spells, unless the players are also 20th level there’s no reason why they’d be the ones to save the world when every city has a godlike wizard.

Your story just seems very Antagonistic, but maybe I’m misinterpreting it. Regardless you do you.

 so, everytimes a caster int he party uses a spell, your other spellcasters or your monsters becomes suddently dumb and forget what spells are ?
seems pretty strong for players if you let them have it their ways all the time. my monsters can do it too, and they have used it with great effect. players too. but its not something that is used for combat. its a siege weapon. just doesn't work well against casters who have ways to find you and stop you. even more at high levels.

 You're not wrong that people don't become dumb and don't realize that "Hey, this is unnatural, someone's messing this up" but Scrying is a bad choice here unless the BBEG knows who could be the one casting it. The only things you can target with Scrying are either a "particular creature" (and I am pretty sure "someone casting Control Weather in this area" isn't a valid designation) or a "particular location, where you can't move the sensor" (so you have to be lucky and pick the spot from which you can see the spellcaster).

However, there's a much simpler solution - just cast Dispel Magic in the area. Even if you don't have/want to spend an 8th level, you could simply hit DC 18 on average in 3rd/4th casts (and if you have apprentices, just command them to do so)

 This doesn't actually work. The spell has a range of self, meaning the valid target for dispel magic is the caster. You'd need to find the caster to dispel the effect.

Because if you use 6 5 5 combo you get an insanely strong blizzard in artic cold with hurricane winds

 You can create counters to player tactics without just directly nullifying it. You have to allow your players to shine somehow because they are the ones playing the game.

Like, what reason should anyone get this spell if this is how it's treated anytime someone finds a creative use because it's very niche as is since no one really gave a "common" use for it except for you... which seems to have been made useless in the niche scanerios it'll come up being an 8th level spell.

Hey, if your DM agrees, super easy to make a homebrewed version of this spell that works exactly the same way that gets added to the Storm Sorcerer's spell list.

 wheres the fun in the game if you just made it to contain the players?

and players are different than npcs. the phb states that every player is special from the start on, so the things your players can do are not meant for all npcs.

shame the effects of the spell always hit you as well

Silver Dragon's lair action

• Once per day, the dragon can alter the weather in a 6-mile radius centered on its lair. The dragon doesn’t need to be outdoors; otherwise the effect is identical to the control weather spell.

Shouldn’t the Hail or Driving Hail deal bludgeoning damage?

My Storm Sorcerer just learned this spell as a story reward, and he absolutely plans to begin using it as a method of amassing worshippers and ascending to godhood, or at least starting a big ass cult. He can use wish to cast Temple of the Gods with an open concept design and change the weather so that the crops around him flourish. People will be tripping over themselves to gain his favor xD

Too bad it can't make the clouds rain poison dart frogs.

6,4,5 also works well.

yet another spell that storm sorcerers should be able to cast but can't.  

 Agreed!

 They are literally called "storm sorcerers". Why can they not control the weather?
