So what is the meaning of this:

########################

Level Up with Version 44: Satellite forecast, MTG Satellite, 15-day forecast and more!

Windy.com version 44 has arrived, bringing powerful features designed to enhance forecasting accuracy, improve usability, and offer even more tools for weather enthusiasts and professionals alike.

Here's a detailed overview of what’s new:

15-Day Forecast for ECMWF and GFS Models
The ECMWF (European Centre for Medium-Range Weather Forecasts) model has been enhanced to deliver more detailed and accurate 15-day forecasts. Additionally, the Global Forecast System (GFS) model also provides 15-day forecasts. The prolonged forecast is now visible to Premium users on both the map and forecast detail.

########################

If it is as you say, all the 15-Day forecast new mode of ECMWF and GFS in 44 version is useless.

Simply said, I don't understand why to see 15 days in each model's mode, and only 10 days in compare forecasts mode. Either the first one is completely useless or indeed adding 5 more days in compare forecasts mode for GFS and ECMWF would be useful. Or really, I miss something and apologies in advance.

Congratulations for the 15-day- forecasts of the two major models GFS and ECMWF.

But in "compare forecasts", it still has only the 10-day ones.

I suggest the name of "compare forecasts" to change to "all forecasts", in which you will be able to see simultaneously all the maximum-duration forecasts of all the models. Believe me, it is very helpful. And in any case, if a model in the future has 20-day forecast, again it should be visible in "all forecasts", ignoring that it will be the unique in the 16-20-day part. The "compare forecast" is just a subset of the "all forecasts", and the users can easily do with just their eyes the comparison of some models in the common parts. Or for example, if you are interested in the forecast for a trip after 15-16 days, you want to see the two models for the 15 day and simultaneously the unique model for the 16 day.

Are there any plans by the developers?

@idefix37

So this division-by-3 issue in 1-h forecast, looks like it's kinda front-end? Will it be solved?

@Franckielestore

Yes it is true, I confirm it, but it only happens in the precipitation of Meteoblue. I think nowhere else.

In any case, windy premium is not a fraud. Also, you don't have to worry, you can take your money back the first 14 days.

@Gkikas-LGPZ

I want in the android app to select a location and then to click compare forecasts. Then I want to see all the models with the maximum days forecast each.

Imagine that 100 mm precipitation is coming after 10-12 days. I want to compare ECMWF with GFS in the 10th day and at the same time to see what ECMWF thinks about the 11th-12th days.

Imagine two football players having scored 10 and 16 goals during a season. If you want to compare them, is it meaningful to ignore the last 6 goals of the second player and to just compare the first 10 of both?

@Suty

Hi. Would it be possible to keep both the ECMWF ones separately? For example what if I want to compare the HRES and AIFS for the tomorrow forecast?

In any case, the 16-day-forecast of AIFS should be in the "compare forecasts" mode, and marketingly speaking in the premium ads, the "10-day forecast outlook" should change to "16-day forecast outlook".

But I stillI don't get it. Is there any benefit, even inside France, to use the 2.5 instead of the 1.3? Why do some prefer the 2.5?

@Markusbouman

I don't understand you and the others. For example, I search for Schiermonnikoog, and I can see the Arome 1.3 km version being active.

What do you mean? Maybe you are talking about its duration, being just 1.5 days?

At the moment, if I choose the ECMWF model alone, its 16-day-forecast is visible, but if I choose the "compare models" mode, both GFS and ECMWF stop at 10-11 days.

Will the 16-day-forecast of ECMWF be visible on the "compare models" mode?

Actually, it is one of the most interesting models. An AI version of ECMWF.

Is there a plan in windy.com to add it?

@Richard-Burrows

Well, I mean, for any app on Android you can use any version you want: Just you google for the apk of the specific version.

Actually, on my phone more than half of the apps run in the version that I want. Just, when I have free time I "update" some of them for checking the latest versions.

Are there any plans of adding some new models for Europe - Mediterranean (I live in Greece)?

At the moment there are 4:

GFS 22km
ECMWF 9km
METEOBLUE
ICON-EU 7km

@idefix37

Yes, you're right. I had wrongly supposed that the logical operator is "or" but it is "and". Thank you.

I confirm that they don't work properly.

The Windy Radar needs reinstallation from scratch (after the last update I deleted it from my home page and then I installed it again). Also the play button needs to be pressed 2-3 times, 2-3 seconds to start working.

The live camera needs much time to start working every morning after reconnecting to internet.

I don't get any notifications / alerts for my favorites, neither on my phone nor on my email (I have checked both inbox and spam).

Any advice?

What is your opinion to have a new model as the average of all the other models? or with custom weights / coefficients, free to anyone to choose them, for example 0.2 for GFS, 0.3 for ECMWF, 0.4 for METEOBLUE and 0.1 for ICON-EU?

I am sure it has already been asked and the windy team has already analysed it. So, what stage are we at?

This is a feature in the "New" section, in the version 39: "What's new, version 39".

Can someone explain to me what exactly it is, since I thought that it was available in 38 version as well?

@idefix37

So, I mean, can I ask somehow the programmers team to put this feature in the coming updates? how? Are there somewhere suggestions for the next updates?

@idefix37 thank you for the answer.

Two more questions:

1. On the sounding forecast there is the ICON model which does not exist in compare forecasts, while the METEOBLUE exists in compare forecasts but not in sounding. Why does it happen?

2. Wouldn't it be more practical to show the reference altitude (model elevation) in the compare forecasts mode? 5 altitutes: the average geographical altitude of the region and each model's reference elevation of that region.
