I can highly recommend the Windy.com app, it has a fantastic widget that displays rather detailed 5-day forecasts, including wind, which can be very useful and important depending on where you are and what you plan on doing. I started using it because Apple Weather widgets have a laughable information density and only the most basic metrics.Got my first iPhone in 2009, moved from Windows phone. Yes, I love it, AND... that was the last time I could have 5 days weather displayed on my lock screen. C'mon Apple!
I almost solely use this widget for my weather forecasts (with 2 others for UV and air quality), it practically replaced Weather and is much more accessible in the Widget Library or whatever that space to the left is called.
