Try the Norway Lights app (Android version here). It's powered by the official "Visit Norway" and seems pretty good. Its forecast by default loads the following locations: Alta, Andoya, Bodo, Harstad, Kirkenes, Lakselv, Narvik, Lofoten Islands, Tromso. But the app also offers a search feature that enables you to search for the forecast based on you location (gps or city name).
