Frost risk by date in Blue Springs
Half of springs at Tupelo 2, MS see their last 32°F night by March 21; only one in ten is past it by February 28, and one in ten still has one after April 7. Planting tender crops after March 29 leaves a 30% risk of a frost on them, after April 1 20%, and after April 7 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 71% of the 96 Mississippi stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 10 in half of years, as early as October 30 one year in ten, and holds off past November 28 one year in ten. A hard freeze of 28°F follows 12 days later, around November 22; in spring the one-in-ten date for 28°F is March 25, 13 days before the 32°F one. The freeze-free season lasts 237 days in a typical year, shorter than at 54% of the 96 Mississippi stations; it reaches 260 days one year in ten and falls short of 212 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 70%.
