Hello fellow Oregonian!! We live just around the corner from you on I-5 in Ashland! There really isn't any trick to acclimating flytraps. They do just fine in most cases being put straight outside. If you live in a sunny and hot place, which you don't, they should be slowly introduced to sun, but this time of year even that isn't necessary in most places.
Over on the coast in Winchester Bay, I'd say just put them in a sunny windowsill until this huge storm passes and then try to get them outdoors as often as possible when the weather is above freezing.
Good luck with the big storm coming tomorrow :)
