We are facing cool temperatures too here, fruits are about 20mm now, and we spent 4 days with temps between 2 and 6 degrees Celsius (35 to 43 F) this is new for us. I suppose this will drive to a huge natural drop ?

We are a week to 10 days past PF, and fruit size is on ave 8-12 mm. Does anyone have previous experience with cold temps at this stage that they could share? Thoughts on approach to thinning, what fruit damage to expect, etc. I think we were at these temps for just an hour or two.
