Frost risk by date in Winona
Half of springs at Tyler, TX see their last 32°F night by March 7; only one in ten is past it by February 17, and one in ten still has one after March 27. Planting tender crops after March 15 leaves a 30% risk of a frost on them, after March 20 20%, and after March 27 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 51% of the 339 Texas stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 21 in half of years, as early as November 4 one year in ten, and holds off past December 9 one year in ten. A hard freeze of 28°F follows 13 days later, around December 4; in spring the one-in-ten date for 28°F is March 15, 12 days before the 32°F one. The freeze-free season lasts 257 days in a typical year, longer than at 61% of the 339 Texas stations; it reaches 285 days one year in ten and falls short of 230 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 90% of winters and 16°F in 19%.
