Current Chill Hour Situation

I am monitoring ( as well as other sources for projected chill as of today 1/2/2018 we are around 500  hours which is nearly 100 hours behind our historic average on chill.  If you follow the projected chill probabilities we could be anywhere between 700 and 900 hours by February 1st.   This projection line has dropped slightly with the new long range forecast for above average temperatures.

If this projection holds true we would have adequate chill for many varieties but could be marginal on our higher chillers for the 3rd consecutive year.  Although we now know that hydrogen cyanamide will not save a crop we do know that in a marginal year it can help with dormancy breaking in leaf buds which should result in less quality issues.
