They have arrived, probably more of the same tomorrow.
Time to head to Notch Hill to video the trains appearing and disappearing through the fog. Notch Hill is just high enough up from Shuswap Lake to clear while the rest is fogged in. And it doesn’t hurt that there are hefty grades going East and West.
Speaking from experience this is the worst time of the year for railroaders. 
Well at least for engineers, when the fog starts rolling in. Where I worked between Seattle, and Portland it became fog alley for most of the trip from early October-January. It’s weird and exciting to be rolling along at 50 mph on a clear block, and only see the blocks pop out of the fog right on the nose of the locomotive, but its a completely different ball game when you’re running on restricted blocks and you can’t see 20’ past the nose. You learn the territory really quick by counting curves, crossings, etc between blocks.
Now for railfans it’s completely different 
Take some shots and I’d be interested to see them.
Almost like an Instrument Landing System approach to a carrier well offshore, when the carrier is the only landing field for 1000 miles and it is socked in at 0/0. The pilot can’t see anything until the wheels touch down and the hook catches the wire.
