Live weather is still inaccurate - 1.15.10 update did not fix bug

OK I’ll show the Problem:
Original Weather (Webcam)


SIM LIVE Weather

Test with Ureal Weather Mod (Here the Datas are the right from METAR and ATIS is telling also the correct METAR Datas)

Which one looks correct?

LKPR still rain… :smiley:

Unreal weather mod here will of course look like the more accurate one, because it’s injecting cloud and percipitation based on METAR data alone.

The thing to understand with the in-built weather is for the cloud and percipitation it is based on a forecast model, not the current METAR data. For that reason there will always be some variance compared to the current real world weather. In this case the forecast for LOWW for right now, was rain showers and that’s what we’re seeing in-game. Indeed there is rain showers all around that area in real life.

hmmmm,

looks like we’re strating going back from main point - why some users have other weather than we have :slight_smile:

Am I wrong if I say that I expect sim presents data to all users +/- same if set Live weather? I think so, why some users can have other data at same place as we are. This is question!

Maybe - but the Datas from METAR are not correct with real Live Weather. ATIS is changing the Info if i change the Weather from Unreal Weather MOD (which shows the correct datas) and LIVE Weather. Here I get wrong Datas!

you have to understand that the live weather isnt METAR based, which is a good thing.
If you want METAR based weather, you have to buy REX, but that comes with its own limitations.

I have REX and honestly, i never use it anymore. METAR based weather is a thing of the past. Its just annoying when you have overcast in front of you and 10mins later when it reads the METAR of an airport that reports almost CAVOK, the overcast suddenly disappears.

Also, as you probably know, METARs are like a “screenshot” of the actual weather and is basically outdated in the second it gets published. Not entirely but i guess you get the point. The METAR can be more than 1hr old and is NOT an accurate presentation of the actual weather.

I will admit, I am totally confused about MSFS live weather …

If I set MSFS to LIVEL WEATHER, can I see any sort of representation of what the data being supplied is, apart from just LOOKING at the scenery.

Would it help is LIVE weather populated the Weather Interface with its data, like other settings do ?

METAR based weather programs are still better than completely inaccurate “forecast” weather that we have to deal with with this MSFS Lie Weather. Also, if the programmers of 3rd party weather programs do it correctly, they can analyze many, if not hundreds of metars within a certain proximity to you and blend the weather so that it’s just as seamless and good lucking as MSFS Lie Weather.

True, and people sometimes forget that nobody measures the atmosphere everywhere at all times. The sensors just don’t exist. The price for having a very believable, coherently simulated weather system that develops realistically over time is that most of it is generated by a forecast model. To make METAR data blend into the rest of the weather seamlessly, compromises must be made.

I think it would be beneficial if we had a slider going from “maximal local accuracy” to “maximum coherence”, or something. I never fly on VATSIM (yet) and care much more about how believable the weather is than how accurately it matches real weather at this precise moment in time at my departure/arrival airports. For others it’s the other way around.

And then what about METARs which report CAVOK of NCD (No cloud detected) When the ceiling is above 5,000ft like a lot of METARs here in the UK do? There’s certinaly limitations to both METAR and forecast, in an ideal world we would have some sort of blend of both :slight_smile:

Yes, I agree. If they could blend the two, that would be the best possible scenario.

Very good point!

That slider is very long time existing (hope with this functionality) in one very famous weather product :slight_smile: really oposite to this, I want still Live weather due it’s interesting forecast system. Question again, why some users have at same place as we are different weather? This is probbaly direction to which we need pay attention with MSFS Live weather…

I disagree on that, id take the MSFS liveweather anytime, unless we will get something that is better than REX in interpreting multiple METARs, but even then, this will also not be exactly the weather you have IRL, it will just be a guess. So i rather prefer a forecast that is, in most cases, working very well, instead of a “generated” weather based on METARs.

The important things like pressures and wind where almost 100% correct for me when flying on vatsim. Pressure was of by 1millibar once but otherwise was always matching the METAR. And pressure is more important than having the exact cloud over your head as IRL.

Just completely disagree.

Just as a comparision, how does XP deal with live weather ?
(I do not have anywhere near current XP anymore)

Hi @N6722C! It is metar based in the default sim. I also use ASXP and that is metar based as well. I you are not using a flight plan I believe it’s interpolated from nearby reports. Usually both are accurate and dependable. Although the NOAA site where XP gets the RW weather had issues recently. Resolved now I believe.

absolutely. Peoples get too obsessed with LiveWeather. A 1:1 100% accurate weather in sim as IRL will probably never happen.

Things are starting to get off topic rapidly. We can’t expect any sim to depict exactly what we see out of our windows. Wind, Temperature and QNH are taken from the actual METAR as was oftentimes stated, the rest is from the meteoblue weather model, which is accurate to some degree - and when there’s CB or TCU advertised in the METAR it hints at unstability in rthe atmosphere and the weather model from meteoblue will depict exactly that: random rain in the area. That randomness is something we will have to accept I guess.

Why would we expect that? I think it is reasonable to expect cloud coverage, wind direction and speed, pressure, etc. to be reasonably close though. That is not the case for me. WX was completely incorrect across the entire US this morning in MSFS.

As it was for me in Europe, but since approx. 11:00Z it’s way more accurate.
