Frost risk by date in Centreville
Half of springs at Woodville 4 ESE, MS see their last 32°F night by March 11; only one in ten is past it by February 20, and one in ten still has one after March 31. Planting tender crops after March 20 leaves a 30% risk of a frost on them, after March 25 20%, and after March 31 10%. The 20 days between the even-odds date and the one-in-ten date is wider than at 64% of the 96 Mississippi stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 17 in half of years, as early as November 2 one year in ten, and holds off past December 4 one year in ten. A hard freeze of 28°F follows 14 days later, around December 1; in spring the one-in-ten date for 28°F is March 18, 13 days before the 32°F one. The freeze-free season lasts 251 days in a typical year, longer than at 77% of the 96 Mississippi stations; it reaches 277 days one year in ten and falls short of 224 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 97% of winters and 16°F in 32%.
