Narrative:

Maneuvering to land during approach to jackson hole airport GPWS terrain warning sounded as airport came into view. Continued approach and landed jac. Emphasize being on 186 degree radial within 16 mi DME below 12000 ft. WX also a factor as clear below 12000 ft. Reported WX turned out to be clear below 8000 ft, not 12000 ft. Reported WX led pilot to choose VFR approach when IFR WX conditions existed. Still tracking in 186 degree radial to jac would avoided terrain warning.

Narrative: MANEUVERING TO LAND DURING APCH TO JACKSON HOLE ARPT GPWS TERRAIN WARNING SOUNDED AS ARPT CAME INTO VIEW. CONTINUED APCH AND LANDED JAC. EMPHASIZE BEING ON 186 DEG RADIAL WITHIN 16 MI DME BELOW 12000 FT. WX ALSO A FACTOR AS CLR BELOW 12000 FT. RPTED WX TURNED OUT TO BE CLR BELOW 8000 FT, NOT 12000 FT. RPTED WX LED PLT TO CHOOSE VFR APCH WHEN IFR WX CONDITIONS EXISTED. STILL TRACKING IN 186 DEG RADIAL TO JAC WOULD AVOIDED TERRAIN WARNING.
