Weather app

Are you referring to the Weather Channel icon?

That has been removed.

You can tap on a day in the 10 day forecast and get a hourly graph of temperatures. You can drag your finger across the graph to see temp for a specific hour.

Why can't you see hourly info for other days?

Tap on the day you want to see info for and it should open the forecast, and you can drag your finger over the temp graph to see temperature for specific hours.

You can of course just go to the Weather Channel website directly and see that information there, or download the Weather Channel's own app and see more info than Apple's Weather app provides.
