It would be great if we could set up an alert for when forecast lightning flash density or CAPE exceeds a certain value of our choosing at a location.

I’d imagine it wouldn’t take too much time to add this capability since it would just be using the same technique as the existing alerts we already use for other parameters such as wind speed, temperature, etc…. except it would just sample the gridpoint value of forecast lightning flash density or CAPE.

Even better would be if such an alert could be triggered when a combination of both lightning (or CAPE) and 500hpa wind speeds (a proxy for shear) exceeds a certain threshold. This could provide a useful heads up on the potential for severe thunderstorms.

@Ondřej-Šutera Ah thanks very much for that! The sounding option doesn't appear for me at first unless I scroll to the right in that section so that's why I didn't see it at first.

@Suty said in animation feature removal:

@ccarawan @Nezolikesrain Possibility of creating your own animation was removed because of high number of bugs there and low usage of this feature on the end of users.

@Suty have you seen all the animations that were still uploaded every single day to https://community.windy.com/topic/8191/your-animations/36468 by the sheer number of people who were still using that feature?

That includes myself. Not sure how that could classify as low usage. Nor the statement that there were a lot of bugs. I only experienced one single issue but was able to work around it.

Even to this day, I personally don't know of any model website that had an animation feature to this standard so it's very disappointing that this has been taken away. Especially considering some of us are premium users paying a fee.

Thanks very much to the Windy team for recently adding ACCESS-C to the list of models for Australia in the desktop version, but can you please extend the 18z runs of ACCESS-C out to its full 42 hours rather than just 36 hours?

The 00z, 06z, and 12z runs only go out to 36 hours but the 18z run was increased to 42 hours a few years ago as a result of forecaster feedback.

Not sure whether this is a bug or it's been intentionally left out but I'll post this question in here just in case it is a bug.

Just wondering where has the ability to long-press on any point on the map to view a model forecast sounding gone after the latest UI update to the app?

Adding precipitation types such as rain vs snow vs freezing rain (perhaps using colour-coding) to work out where snow would be more likely than rain would be great!

@korina oh and sorry, one more suggestion before I forget. Not sure if this deserves a separate thread but it would also be extremely useful if there was an optional setting where alerts extend out to 7 or 10 days.

I know accuracy is lower at that type of range but if it was available as an option that could be turned on or off by premium or more advanced users (while keeping the default alerts to 5 days unless the user forces a change) and adding a disclaimer that skill will be lower, I think it would be a great addition.

I'm a premium subscriber and I'm also unable to use the right arrow key to step forward through the forecast timesteps in the desktop version of Windy.

This occurs in both the Microsoft Edge and Chrome web browsers.

One of my friends who's a premium subscriber is also having the same problem in Chrome.

P.S. Using the left arrow key to step back through time also reveals a bug where it steps back using excessively coarse time intervals e.g. 3 hour increments in the hourly ECMWF forecast with forecast times (those times don't even match up with the model's 03, 06z, 09z, etc times either).

@Korina thanks very much 😁

@Suty is there a need to remove it, considering it's been so useful for so long and that it's never had any problems until now? (none that I've personally experienced anyway)

It would be extremely disappointing if that were to happen.

@idefix37 thanks for that,

@idefix37 said in Weird values for MSLP isobar labels are being displayed:

@Ken
These figures come from the setting of Isolines in the menu. You have selected Geopotential heights which give these values at sea level.

Ah so I have @idefix37 , thanks for pointing that out.

Not sure why it defaulted to geopotential height though, because I hadn't manually changed that setting before and wasn't even aware it existed in Windy (is it a new feature?).

I noticed someone mentioned the same issue on this forum earlier as well.

Which pressure surface are those geopotential heights for? They seem to be far too high and low for 500hpa i.e. they range anywhere from about 100 to 700dm depending on the area.

Very weird values for the mean sea level pressure isobar labels are being displayed in Windy at the moment - refer to the screenshot below.

I've made sure that I've set the pressure units to hPa and that the height for all the height-adjustable variables are set to the surface, but no luck.

I've also tried logging out and logging back in, clearing my browser's cache, done a hard refresh, checked the other models, etc.

At first, I almost thought it was displaying 500hpa geopotential heights but the values are way too low/high for that.

This problem only seems to happen when I'm logged into the desktop version of Windy - it doesn't seem to happen when I'm logged out or using the mobile app.

@idefix37 said in When are 15 day forecasts coming?:

@Ken

The way the rain or wind accumulation is displayed in the browser version (with 2 sliders) is not possible on a small screen. It is used on iPad with the mobile app because it has a larger screen.
Then a 15-day forecast has very low reliability at a local scale. This is not such a big shortcoming.

By the way, when you say

I was referring to the accumulation layers of rain and wind as in the screenshots below.

No, in your first message you were not referring to these layers and you modified some of your posts later.

@idefix37 not being able to have two sliders on a small screen is understandable. But is there a way to at least add a 15-day option at the bottom that we can tap on (in addition to the existing 12hrs, 24hrs, 2 days, 4 days, and 8 days option?

I fully realise a 15-day forecast period has lower accuracy but if you consider the accuracy that low, why even have it on the desktop version in the first place then?

I would've thought the whole point of having an app and website like Windy was to show the raw forecasts from the models, even though it's well known that accuracy is significantly lower beyond about 5 days. Hence why so many weather websites out there show model forecasts out to their full forecast length,

As for my 1st post, I edited it to say "accumulation" to make it clearer and avoid any confusion.

I also said "accumulation" in my 2nd post (my initial reply to your post) which I didn't edit at all if I recall correctly. There's no edit history to that post that I can see. Refer to above screenshot.

I edited my subsequent posts to make them clearer.

@Ken
Have you tried wind, temperature, rain .... layers?

@Gkikas-LGPZ I was referring to the rain and wind accumulation layers as per the below screenshots.

The desktop version of Windy has had 15-day forecasts for both of those layers for a while now but not the mobile app version.

@idefix37 said in When are 15 day forecasts coming?:

@Ken
The mobile app provide also 15 days forecast for ECMWF and GFS. May be you need to update it.

@idefix37 not for me. I even tried uninstalling and re-installing the app as well as logging out and logging back into my premium account but it still only shows up to 8 days for the rainfall and wind accumulation layers - see attached screenshot.

For reference, I'm using an iPhone 16 Pro with iOS 18.3.1

The desktop version of Windy has had 15-day ECMWF and GFS forecasts for the rain and wind accumulation layers for a while now but the mobile app only goes out to 8 days (which is even shorter than the 10 days that it used to be).

When are you planning to make the 15 day forecasts available for the app to align with what that desktop version already has?

@Filip_K said in Please extend 18z ACCESS-C out to its full 42hrs:

Hi @Ken, You are right, we're currently using only 36 hours from the forecast because all runs are at least 36 hours long. We might use full 42 hours from 18z run in the future, but I unfortunately can't give You any estimate.

Thanks for the response!

Thanks very much to the Windy team for recently adding ACCESS-C to the list of models for Australia in the desktop version, but can you please extend the 18z runs of ACCESS-C out to its full 42 hours rather than just 36 hours?

@Caefix I totally agree with you there.

All that time and effort put into the animation feature only for it to be abandoned feels like a big waste to me.

And yes, the animation feature in Windy was much smoother than those in any other website or app I know of. Not only that, those smooth animations could show both both rain and thunder (the lightning symbols) together - something that no other website or app I'm aware of, can do.

Such a unique feature wasted.
