Frost risk by date in Welch

Half of springs at Elkhorn, WV see their last 32°F night by April 24; only one in ten is past it by April 11, and one in ten still has one after May 14. Planting tender crops after May 2 leaves a 30% risk of a frost on them, after May 6 20%, and after May 14 10%. The 20 days between the even-odds date and the one-in-ten date is wider than at 79% of the 84 West Virginia stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 17 in half of years, as early as October 5 one year in ten, and holds off past October 30 one year in ten. A hard freeze of 28°F follows 9 days later, around October 26; in spring the one-in-ten date for 28°F is April 30, 14 days before the 32°F one. The freeze-free season lasts 175 days in a typical year, shorter than at 60% of the 84 West Virginia stations; it reaches 194 days one year in ten and falls short of 153 one year in ten. On average 120 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 12 days longer, to about May 6, and return around October 9. Severe cold of 16°F or below comes every winter, usually between December 4 and March 4.
