Global warming.

If we get a good cold snap it may kick it back into line and you could get more blossom later. If the mild weather continues then it will assume it is spring already and continue with its normal progression, so no more blossom.

I have a load of rootstocks waiting to graft and hoping that the scion donor trees don't kick into life too soon.
I also have a peach tree in a greenhouse that still hasn't shed all its leaves.
