Approximately 44 miles west of Boise, Idaho, the pilot received an in-flight weather update for the intended route. The weather specialist advised the pilot of areas of thunderstorms, icing, and mountain obscuration along the route. The specialist further informed the pilot that VFR flight was not recommended in areas of higher terrain.

Wreckage Discovery
The airplane wreckage was later located in mountainous terrain approximately 40 miles southeast of the pilot's planned destination. Widespread areas of instrument meteorological conditions were reported along the pilot's route of flight.
