My understanding Art is that several warm, very cloudy days result in carbohydrate stress and therefore increases thinning. That said, assuming that your soils are waterlogged due to several wet days bordering on being snowy up there in Maine, the carb stress is not pronounced. I'm just starting to see the effects of thinning sprays applied two weeks plus ago as we've been staying in the 40s/50s too. So far thinning effect has been what I would consider modest (except Honeycrisp which appear to be thinning quite nicely!).Warm weather predicted for weekend will tell us more and probably give you a good opportunity if your fruit is still in susceptible range. My two cents.
