Please count my vote for that too.

@yves70 I understand. Thank you.

This has already been requested one year before [https://community.windy.com/topic/5530/heat-index-and-wind-chill] and three years after, it's still missing. Would be so happy to see this in Windy.

Just found out that there are actually (more or less precise) charts for Wind Chill and Heat Index:

https://www.weather.gov/safety/cold-wind-chill-chart
https://www.weather.gov/safety/heat-index

(and their respective, easy-to-find Celsius counterparts).

That is one more step but will do the job for me (I'm a hiker/runner). It would be so nice to see this in Windy! It's an immensely helpful value.

@yves70 I understand. Thank you.

@idefix37 said in 1hr and 3hr forecast differ?:

@plusterwurst
Could be possible rainy/snowy conditions with less than 0.1mm sometime within 3hours... probably?
But you have to note that 0.1mm is almost nothing, so don’t focus too much about it. A chance of more or less nothing, spread over a large area (7km x 7km as forecast by ICON-eu) does not give so much.

@idefix37 Well, if that's the case - if there's less than 0.1mm of rain then there's no bar at the bottom but a rain/snow symbol at the top - we should see the same behaviour in the 1hr forecast as well, right? But as my 1st screenshot shows this is not the case: there's no symbol for rain at around 4pm in the 1hr forecast but rain symbol + bar in the 2nd.

And I know - this amount of rain is not much. But in my city there is a special weather situation. Drifting effects with strong westerly winds direct the showers mostly north or south past the city - but sometimes just above it. And often that's exactly when these small amounts of precipitation are predicted. This helps me to be well prepared for possible precipitation, so I want to be able to interpret the meteogram accurately.

@idefix37 Okay, that seems to be an FAQ. ;-) Thank you.

Interestingly enough there's that as well:

Symbols at 10, 13, 16, 19hrs show snow/rain but the meteogram does not show any precipitation. Is there an explanation for that as well?

Hi! This is the 1hr forecast for my place, firecast-model is ICON-EU. It does not show any rain in the afternoon:

This is the 3hr forecast, same model, same place. It shows 0.2 rain expected around 4pm:

1hr and 3hr models show different values for certain parameters. This is not the first time I see that. Why's that? I assumed the 3hr model is based on the 1hr forecast which means that if there's no rain expected in the 1hr forecast this should apply to the 3hr too. Am I wrong? What am I missing?

@korina Hi Korina, tried it with another installation of a Firefox Nightly and you're right, it works as expected. I had a look @ my about:config, and I think I found the problem:

privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts was set to true to avoid tracking/fingerprinting of my browser. This seems to be a needed function for the correct display of the layers in Windy. When I set it to "false" and restart my browser, everything works fine. Anyways, this is a popular feature for security-minded people and there are also canvas-blocking addons installed by many people. Maybe you can pass that on to your developers so they can see if there is way to fix that? Thank you.

Hi, in Chrome everything works fine for me. I prefer Firefox, using the current version. But none of the layers is usable for me, I just see weird colors. When I open the Radar, I see this.

Pretty similar: the temperature layer.

Same for clouds, air quality, rain ... whatever.
I tried to disable WebGL, doesn't change anything. Error console says everything is fine. I also disable all add-ons: changed nothing. Any hints what could be wrong here? I assume everything should work as expected since FF is a popular browser.

Thanks.

@petra-pik Thank you. Looking forward to this and the other new features you're working on. I really like this service! :-)

@laurentperinet Good point. I almost always use Meteoblue as it tends to be the most accurate model in my region.
