The BBC Weather website currently has a 'beta' which you can try out. Presumably the intention is to make this replace the current site in due course. I think it is awful.

Which one of those is more intuitive to you?
To get the same amount of info as before, you need to click on subheadings and scroll down. The images of weather are unclear - they should keep it simple. A black cloud = cloudy. A black cloud with one rain drop = light rain. A black cloud with two rain drops = heavy rain. That is as complicated as it needs to be.
They've also done away with colours for the temperatures which again made it easy to see at a glance, even without actually reading the numbers, how hot or cold it will be. eg. blue for cold, yellow for warm, orange for hot etc.
