Half of springs at Burton, WV see their last 32°F night by May 4; only one in ten is past it by April 20, and one in ten still has one after May 22. Planting tender crops after May 12 leaves a 30% risk of a frost on them, after May 17 20%, and after May 22 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 40% of the 84 West Virginia stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 12 in half of years, as early as October 1 one year in ten, and holds off past October 25 one year in ten.
