Half of springs at Schoharie, NY see their last 32°F night by May 2; only one in ten is past it by April 20, and one in ten still has one after May 17. Planting tender crops after May 8 leaves a 30% risk of a frost on them, after May 11 20%, and after May 17 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 29% of the 173 New York stations behind this site's ZIP pages.
