SF last night told me there was going to be 12cm of rain at the bottom station in Boro on Fri, this morning its now 4cm!
They can only forecast accurately for 48 hours or if the weather was likely to hit a huge area (e.g the whole country like it was a couple of weeks ago.)
No point looking at it if you've already booked up too, although that hasn't stopped me looking everyday
I just look at the webcams, far better imo for giving an impression of the snow conditions than forecasting because forecasting itself isn't that accurate and trying to predicate mountain weather usually suspectible rapid extreme changes leads to more inaccuracy.
