Windy's Version 41 is here and brings new features!

The radar nowcasting feature is fantastic, especially for hikers/trekkers like me! Love it ❤️ however, rather than a simple optical flow extrapolation, you may want to experiment with one of the numerous machine learning models for nowcasting. See https://www.mdpi.com/2072-4292/15/21/5197 https://www.ecmwf.int/en/about/media-centre/science-blog/2023/rise-machine-learning-weather-forecasting?t https://www.nature.com/articles/d41586-023-03552-y?t Anyway, excited about this feature - I already put it to good use during my last hike, and I’m looking forward to using it many more times!

I noticed the future radar feature came out recently, but when you view the future radar, the map
Glitches. This is on windows ten and my
iPhone 12 doesn’t even have the feature on the windy app. Premium member here n wish they could have improved it before the release. Always viewed Windy as the go to, but now I’m skeptical if they display faulty data -
@Elsa-Ann-Winter
The iPhone does have this feature. I guess you probably need to relaunch the app. -
I do like the Radar Nowcasting but agree with others that it would be nice to have an easier way to return to the most recent radar image. Thanks for the continued improvements!

@PleaseBeamMeUp
You just need to click on the white timeline. So easy. -
@lange-hape Hi, we knew about the huge interest in this feature so we decided to manage it for our users. Regarding the using the rest of the timeline, we still offer same scope, despite smaller visual size.
-
Thanks for the new features. But, really, still no heat index?
-
@Birnam-Brae I agree! This would be particularly useful when travelling to other places so you can carry with you proper clothes. :D
-
Guys, could you please elaborate a bit more on nowcasting? Do models such as Arome and ECMWF provide such thing? And what led you to add it in the first place?
I am not an expert, but wouldn't it be more useful to have a % chance of precipitation map for say like the next 30-60 min? That would be so cool. -
Hi @alphadan
The source of radar data is usually the national weather service of each country. Therefore, a single source or model does not make the weather radar . To be more precise, it's a radar composite of these different sources. You can tell that the weather radar quality varies around the globe (quality = frequency of images, resolution, handling interference, etc.).Since we know the movement of precipitation several hours in the past, we can extrapolate the next movement of this precipitation to the next hour. This part is purely our work.
A chance of rain in the next 30 - 60 minutes would be nice, but you can see it beautifully on the nowcasting radar. :)

@Birnam-Brae
As far as I know, there is no such thing in the plan. The wet-bulb temperature layer can do the trick pretty well, don't you think? -
Windy Radar is an accurate and detailed source at this time and I use, although I still combine with the situation and conditions real time, as well as using weather aids, due to activity in SAR (search and rescue) and often in disaster areas in Indonesia (at the moment hydrometeorological disaster is happening in Indonesia).
Thank you for the update and I hope to go ahead with more features that are granted without reducing accuracy and precision levels. -
Dear users! Thank you all for an elaborative feedback.
Our team has read through your replies and we decided to award @mstriker with a Windy sweatshirt! Congratulations! Please contact me through DM.

@idefix37 The radar forecast is basically a model. What's in the past is real radar data. You only get 1 hour free nowadays. That's why you will not get 12 hours free because you can't get 12 hours in the past for free anymore. Now, 12 hours would be more reliable than say 72 hours. In summer, such short-range models even for one hour cannot handle thunderstorms very well. Especially the HRRR, which Windy already has. So, you might be disappointed even if there WAS a 12-hour free forecast of radar. You might just be better off with the 1-hour outlook.

@idefix37 said in Windy's Version 41 is here and brings new features!:
The radar loops for 12, 6, or 1 hours in the past are NOT a forecast ! It is observation by real radars installations, while the “nowcasting” is just extrapolation of the last picture of the loop. Are you really thinking that extending this extrapolation during the next 12 hours would be reliable ? You would be very disappointed in stormy and convective weather.
This is what I said in a previous post here above. So why are you trying to explain to me what I know ? Read again my post.
Then there is no connection with the fact that the past 12 h and 6 h are not free and with the possible extrapolation duration. -
Well done Windy
-
good job windy
-
Nowcasting has nothing to do with physics (as you describe it it is only a calculation based on what we see on the screen prior), so it's useless.
-
@Polina-Nozdrina I love windy, but premium plans too expensive for me in third world salary, hope there will be discount event
-
@Polina-Nozdrina the Radar nowcasting is a valuable tool. I really liked it. Greetings from Brazil.
