Narrative:
En route to portland, pdx, approximately 1 hour 30 mins from landing received a dispatch message via ACARS, WX in pdx 0.25 mi, RVR 100 ft fog and no operations in pdx in the last hour. Forecast for no improvement. They requested we fly to sea. We contacted dispatch via voice to discuss options. The WX in pdx leaving ord was scattered, 10 mi visibility, temperature 8 degrees, dewpoint 4 degrees, calm winds. Forecast to remain good for our arrival. The WX in sea was ok but temperature dewpoint spread 1 degree, and more importantly all suitable alternates for sea/pdx fogged in. I felt sea was not a good choice. Our arrival fuel would have been 5000 pounds. We were approximately 150 mi from boise (boi), WX excellent so I elected to land boi. On ground talked to WX. Conditions to improve pdx in 1-2 hours. Svced and refueled, we monitored the WX. Once improving, we departed for pdx and landed uneventfully, RVR 2200 ft variable 2800 ft. We used runway 10R CAT ii.
