Frost risk by date in Corinth
Half of springs at Corinth 7 SW, MS see their last 32°F night by April 2; only one in ten is past it by March 16, and one in ten still has one after April 17. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 11 20%, and after April 17 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 94% of the 96 Mississippi stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 1 in half of years, as early as October 20 one year in ten, and holds off past November 15 one year in ten. A hard freeze of 28°F follows 10 days later, around November 11; in spring the one-in-ten date for 28°F is April 6, 11 days before the 32°F one.
