We'll be going through freeze/thaw cycles over the next few days, which means the trails will fluctuate between soft and slow (mid-day), and icy and fast (mornings and late afternoon/evening).  I recommend that less experienced skiers avoid the hill trails when conditions are icy.  Grooming activities will be limited until we get some new snow, but the existing classical tracks are still in great condition. 
Concerning the late week weather forecast: Think COLD!
