Weather data for Sanford ME.  Forecast values begin November 1, 2011
Potential preharvest weather influences on Storability, Preharvest Drop, Color, and Storage scald risk
As of November 1, weather data do not suggest increased storage risk due to low average August temperatures, or to hot dry periods in August or September.
General outlook (no account for crop load, drought, or other stresses) for when drop of sound non-spur McIntosh apples might reach 10% of crop is Friday, September 23 to Saturday, September 24.
Weather conditions that promote optimum fruit color begin Wednesday, September 21
Weather data indicate 165 chilling hours will have accumulated by Monday October 10.  Research found that 500 ppm DPA for Cortland & 1000 ppm for Red Delicious is adequate for fruit harvested on or after October 10, and kept in Refrigerated Air storage.  Limited data suggest that same may also be true for McIntosh.  This is also the best guess for storage scald risk in Controlled Atmosphere storage.
