Jesus won't help ya man but you should be fine by the 17th. Some rain won't destroy the base so there will be plenty to shred..however, can't speak for the woods, Just gotta be patient.
My only time skiing Jay was 6 years ago in January and the 2 days I went the highs were in the 40's/50's with passing rain. 2 feet at the least in the woods but it was hella fun and a bummer at the same time.
