Half of springs at Tuskahoma, OK see their last 32°F night by April 11; only one in ten is past it by March 25, and one in ten still has one after April 27. Planting tender crops after April 18 leaves a 30% risk of a frost on them, after April 22 20%, and after April 27 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 61% of the 114 Oklahoma stations behind this site's ZIP pages.
