METAR keeps disrupting the weather/ bugged weather/Cumulus/CB clouds only/no medium to high cloud coverage

This bug still needs to be kept at the top of the priority list as far as I’m concerned.

Today we have this high overcast across the whole of the Midlands:

And what do we see in the sim (roughly same location)? Of course, blue skies and puffy clouds, the same as every other day.

By the way, this is an example of how a high overcast looked in live weather before SU7, for those who don’t think there is anything wrong. Makes me want to cry.

Do you have the same issue if you follow the OP’s steps to reproduce it?

Yes

Provide extra information to complete the original description of the issue:

I try to be as constructive as possible:
I know wind, pressure, temp and visibility/fog always matches the METAR 100% all the time. That to me means those things are not blended with Meteoblue data at all. Visibility were added to wind, pressure and temp in su7.

The other thing they changed and added in su7 were the 6 hour of MB data source that included more observational data blended into that 12 hour model. What i understand is that the 6 hour model also uses the 12 hour model but it includes postprocessed data inbetween.

Besides the wind, temp, pressure and visibility/fog that matches METAR 100%. I can’t actually find more things that improved accuracy in su7. That to me means the change to the 6 hour model were completely useless. I think the main issue we see since su7 is the 6 hour model they introduced. If the 6 hour model includes less detailed data to be able to render realistic clouds we also see less detailed clouds in the sim. The generic clouds we see, is the postprocessing of the 12 hour model MB does.

To get the variety and fluidness back that we got used to pre su7 i think the pre su7 12 hour model without post processing needs to be added as an optional feature for us that preffered that system :slight_smile:

Besides the weather issues i really love the sim. Maybe thats why i care so much :wink:

No High Level clouds on my flight even if MeteoBlue is showing a 100% coverage over the zone I am flying to. The clouds shown on the 2nd screenshot are like medium level clouds, same type of clouds I have in 90% of my flights.

Yes. There are no steps required to repeat it.

Provide extra information to complete the original description of the issue:

METARs are disrupting the live weather, and there is an overwhelming lack of cloud structure. The live weather has a ‘flat’ feeling and needs to be reprogrammed to produce more accurate end results.

If relevant, provide additional screenshots/video:


This is an IRL drone image. It may be hard to tell, but there is a distant towering CB cloud with measured tops of 45000FT. You can see the infamous Cumulonimbus flat top. This center of the storm was estimated at 21NM from my location.

And here is the in-sim screenshot (same exact location). The towering CB cloud does not exist in the sim. The sim renders this strange nimbostratus rain cloud, which isn’t nearly correct. The top of the in-sim cloud was only 16000FT, drastically different from the real-life photo, which was 45000 feet tall. The location of the precipitation is also not correct. These incorrect characteristics have been consistent within my extensive comparisons over the last few months.

Certain wishlist items (like weather radar and realistic dangerous weather) rely on the sim’s ability to produce true-to-life weather. It does not do this right now.

Tonight the sim is doing its usual useless job of rendering an overcast layer using live weather. This is something I still miss since SU7 when we used to get wall to wall overcasts. Such a shame.

The definition of overcast is 8/8ths sky coverage so there should be zero sky showing. As it used to be perfectly capable of doing pre-su7.

More example of how Live Weather basically isnt useable anymore… This is Jackson Hole, WY right now 31JUL at 602pm MT, irl there is TS and in sim it is pretty much a clear day. Some clouds here and there but otherwise nothing… So frustrating and disappointing… anyone know if they are gonna do improvements on the upcoming SU in September?

lol I’ve given up hope for weather in MSFS2020 and I’ll just assume the same for 2024 and save myself the disappointment

It would be helpful to post a screenshot showing the Meteoblue cloud coverage at the time of the MSFS view. With evidence like that we could perhaps begin to understand what the source of cloud data in the sim actually is. Thanks!

This is quite laughable, the whole Finland is covered in clouds but accoring to the metar EFHK is blue skies. EFHK 311220Z 17012KT 9999 BKN006 FEW045TCU 19/18 Q0999 TEMPO BKN006. One could also see the metar ring quite clearly in every direction around the airport.


Here’s a comparison from sim and real life from the same location near the airport

I think that shows the limitations of METAR as a source of weather. It also shows that METAR don’t report the complete picture of the sky. I also know the limitations of forecasts, but forecasts reports far more detailed weather. That also shows those type of sources are not compatible. And it also show how hard it is to blend those type of sources. What type of source should have priority? In this case the forecast should have priority but in other cases METAR should have priority.

To get 100% accurate weather in the sim is equally impossible to get as it is to get 100% accurate forecasts.

In my opinion, options would be the easiest way to get most of the users happy. 100% METAR around airports, Metar/Meteoblue hybrid or 100% meteoblue because we will never have perfect weather in a flight simulator. Only plausible weather.

There is no FEW and SCT type of clouds creation/injection. BKN and OVC type of clouds look like same shape every time. Even the Sim is capable to create all type of clouds.

It’s uncanny how the clouds congregate over the stations.

If relevant, provide additional screenshots/video:

I used the bird’s-eye-view map to match the location of a cloud circle to the location of a nearby METAR. They match almost perfectly. It’s difficult to see in dense areas when all report similar conditions, however I hope this helps illustrate that METAR is still disrupting the weather.

The community asked for this feature to be implemented. And the devs added the feature the community asked for. We can notice that on your screenshots. Those screenshots also shows that the added feature works as intended. But in my opinion, that added feature ruined the whole weather experience for me. Felt much more like weather pre METAR-implementation.

Completely agree, always ironic how we demand this and that then call it a bug when it’s implemented, works exactly as intended and we see it in reality.

One of the only things that worked well at initial release was the dynamic weather system. We demanded a perfectly reasonable system be changed because the sim showed winds 10kts @ 050 but the hour(s) old meter read 11kts @ 051.

Can’t lay that one on Asobo, it’s squarely on us. I sincerely hope that generating weather from METARs is done away with, or at least becomes an optional feature in 2024. Sadly I doubt that will happen. We got what we asked for on this one and we’re probably stuck with it.

I hardly think it works exactly as people intended.

I’m pretty sure that not many people would have asked for it in terms of
“Please make it so that METAR stations forcibly override surrounding conditions leaving immersion-breaking cloud circles everywhere and ruining overall cloud structures”

I get that many folks would ask for some means of ensuring better matching weather between RW METARS and the sim, but I doubt they’d have wanted so much if they knew that it’d get done like this.

I’m rather convinced that this isn’t really even what Asobo themselves wanted. They have stated before that there shouldn’t be any effect on clouds from the implementation of METAR blending.
Now, seeing as how there certainly is an effect, and an extremely detrimental one at that, it’s only fair to conclude that things have not gone as planned.

And that, is The Bug this thread is all about. It’s not that people don’t want METAR blending, we just want it done right and in the years since, that has not happened yet.

unfortunately, this issue has not been fixed in MSFS 2024. The weather and clouds quality, and also the depiction is as worse as in MSFS 2020. It’s sad, i was really hoping they will be massive improvements on weather in MSFS2024.
