1) New menu
The menu on the previous version had a sky view (weather visualization), Hour by hour, Graph, Area and Map. In the new version you'll find Hour by hour and Longterm together under Table.
2) Short and long term forecast in the same view
The new table view is the same as in mobile app, with weather symbols, temperature, precipitation and wind direction/strength. You will find the hourly forecast for the first three days by clicking on "Hourly" on the bottom of the day you wish to see detailed forecast for.
The meteogram and probability forecast is not a featured item in the new iPad-version. We are constantly working on improving the app, and probability forecast is one of the things we are looking into for later versions. The old services are still available on our websites, yr.no (desktop-version only).
