Beachboy,
I expect it will be okay by the time you get out there, at the beginning of Jan. I mean, a temperature of 13 degrees C is definitely not 'normal' for 23rd December. I would say it is only a temporary 'blip' :D
They do have quite a lot of snow-making facilities in St Johann, I think they cover 45 Km of piste, so I reckon there will be some snow for you. And you can also get buses to neighbouring areas, like Kitzbuhel, if the open area isn't large enough for you.
We went to Obergurgl (very high up in Austria) the last year there was poor snow, at the beginning of Jan, and I thought St Johann wouldn't have any at all, but my daughter's school went there and there definitely was snow because they all had a great time and brought back plenty of photos to prove it.
So I wouldn't panic just yet.
