They require now to be logged-in to get more than 1 hour weather report. Seems they want more data on you. Let's rename it Yspy. Additionally, the accuracy has very much dropped. If the weather shows a little bit of instability, you cannot rely on it - at all!

Been using for 8 years. Used to be accurate but recently hasn't been, i.e. rain when it says none, etc. But mainly I don't like the updates that's not letting me put weather updates & the snow filters gone on the map (I loved that aspect in winter), bring it back.
