With nights that go below 0, I expect the track will be getting tougher throughout the week, when people train/ride on it while it is thawing.
And I know that on Saturday they predict quite some rain here (which isn't that far away), so indeed the track should be getting more tricky/heavy.
The schute could be tricky if it rains heavily. Both my lads rode World Cups there several years back. One went early and it was dry, the other got caught in this thunderstorm when sections were virtually unrideable. Good place to watch if its throwing it down.
