Half of springs at Mcpherson, KS see their last 32°F night by April 18; only one in ten is past it by April 4, and one in ten still has one after May 1. Planting tender crops after April 24 leaves a 30% risk of a frost on them, after April 28 20%, and after May 1 10%. The 13 days between the even-odds date and the one-in-ten date is narrower than at 65% of the 110 Kansas stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 24 in half of years, as early as October 7 one year in ten, and holds off past November 7 one year in ten. A hard freeze of 28°F follows 8 days later, around November 1; in spring the one-in-ten date for 28°F is April 23, 8 days before the 32°F one. The freeze-free season lasts 187 days in a typical year, shorter than at 52% of the 110 Kansas stations; it reaches 209 days one year in ten and falls short of 165 one year in ten.
