One can see here from the picture kindly provided by Doug Thomas of Crown Nursery that the cold of late is having an effect. Total accumulation of chill by 10/29 in Macdoel when this picture was taken was 364 hours (this is over 329 one week ago) between the critical temperatures of 33 and 45 degrees, offset by 394 + 123 hours above 60 degrees.  

Warm weather has more or less ceased to be a factor here, allowing the chill hours to accumulate much quicker, and it is subsequently showing on the plants.
