"Thunderstorm" were announced today for "Tonight" and next after that is "Gusty" with "today in the morning"(tomorrow in the morning before daily reset).
I first noticed it at 01:12am, when weather forcast still said "Small earthquake". I checked the wiki for the times of change. It said Night 11pm - 3:59am. Sadly I haven't taken a screenshot.

As I checked the weather at 2:07 again Thunderstorms time changes to "soon", wich isn't a time were weather should change at all. Screenshot

Maybe the meaning of the word "tonight" in castform weather is "sometime tonight, it will become thunderstorm"? It may mean that when the night comes, it may not necessarily become a thunderstorm.

You say the Wiki says Night is from 11pm to 3:59 am.
If it said "soon" at 2:07, it means that at the next hour [3:00] the weather will change, which falls within the range the Wiki gives.

So the weather did change when it said it would.

Sorry for the late reply, I was really busy in rl.
Honestly, no it doesn't fall into what Wiki said. 'Cause it should change at 3:59am, but it has changed at 2:59am.

I now have some screenshots to show what I mean and I'll try to explain better.(English isn't my native language)

This is what Wiki said:

ignore the icons upper right, it's a screenshot from my phone and I forgot to cut that out. x')

And here are 3 different examples for the bug:


This is the weather from my original post, sadly I don't have a screenshot that shows Thunderstorm with "Tonight", but as the bug keeps on, I'll show it on the Gusty one.
We can see in the left picture it's 02:07am and Gusty is announced for "Today in the morning". Referring to the weather times from Wiki Gusty will start at 4:00am.
The middle one shows it's already 6:45am, but Gusty still hasn't started as announced.
In the right picture we see it's 7:03 and Gusty now shows "Soon" wich means it'll appear in the next hour. But as Morning is from 4:00 - 10:59 at 7:59 shouldn't be a weather change at all.

Sry for the ugly cut
Left picture shows Thunderstorm announced with "This afternoon", but if we take a look at the clock we see it's 16:40 wich means referring to wiki times wich says Afternoon is 2:00pm - 5:59pm Thunderstorm should already be active since 2 hours. And it shows the Strong earthquakes is announced for "Tomorrow in the evening".
Middle picture shows the next day at 20:59 were Smog is still active and Strong earthquakes announced with "Soon". As "Evening" should start at 6:00pm, St.earth. should already be active since 3h.
Right picture shows it's 21:00 and Strong earthquakes has become active.

As you can see this is an old screenshot from June 2023 wich shows a mixed up weather announcement. "Tomorrow night" is announced before "Tomorrow in the evening". This bug I've seen also several timed, same as sometimes two of the forecast shows the same anouncement like "Tomorrow in the morning" / "Tomorrow night" / "Tomorrow night".

I hope this helpes to understand what I mean. =)

The only thing the Wiki tells you, is when the time zones are.
Nowhere does it say the weather can only change when the time zone changes.

The weather can change every hour. The only thing the forecast tells you, is the timeframe for the change. They're not hard predictions, they're general time indications.

You're right, the very first sentence in the Castform Weather Wiki Page is indeed "The weather may change randomly every hour.", as this page is very old and only seemed to be updated when Rainbow Castform and the Moon Phases came, I assumed this sentence meant to be cause the weather can change from one hour to another.
I wasn't aware of that isn't a fix time of change, cause the text below "There is also a table shows the next 3 consecutive Castform, with the name and period they will appear later." was how I've understood the change. That the announced weather comes when the time zone is active. If that isn't the case there should be a slightly change of wording I think. (It would be even better to set the weather change on the time change especially because of Thunderstorm and its effect on the beach(Eternal Rock), but that's only my opinion and this isn't the suggestion forum)

However, as the change of weather is always announced with "soon" in the hour before the change comes there is still a bug, even if I consider your explanation of how it works.
On the second example Screenshot it's 16:40. So, if Thunderstorm should appear within its announced time frame "Afternoon -> 2:00 - 5:59" then it should have already changed to "soon", cause there are only 1h and 20min left of the time zone. If Thunderstorm would change to "soon" at 17:00(5:00pm) it can't weather change at 18:00(6:00pm) anymore cause that's already the time frame of "Evening".

And what's about the last screenshot? I know it's from past year, but it still happen. Should I try to get a newer screenshot if it happen again?
