Frost risk by date in Warrior
Half of springs at Pinson, AL see their last 32°F night by April 4; only one in ten is past it by March 16, and one in ten still has one after April 22. Planting tender crops after April 11 leaves a 30% risk of a frost on them, after April 15 20%, and after April 22 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 46% of the 115 Alabama 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 21 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 10, 12 days before the 32°F one.
