hahaha,  
  
your best bet for forecasts for BC is Environment Canada or the WeatherNetwork, EC is the equivalent of the NOAA. 
  
Friday good, sat should be fine: weak cold front. Sunday is the iffy day with an upper level low swing by..could go either way as far as showers or just cloud. Monday is good. 
  
I live in Van so its a bit closer of trek for me, thats why I was givin you the heads up. 
  
I may head to angels crest via BL on sat, may see you there.
