Frost risk by date in Leonard

Half of springs at Greenville Kgvl Radio, TX see their last 32°F night by March 18; only one in ten is past it by February 27, and one in ten still has one after April 6. Planting tender crops after March 26 leaves a 30% risk of a frost on them, after March 31 20%, and after April 6 10%. The 19 days between the even-odds date and the one-in-ten date is narrower than at 63% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 16 in half of years, as early as November 1 one year in ten, and holds off past December 5 one year in ten. A hard freeze of 28°F follows 12 days later, around November 28; in spring the one-in-ten date for 28°F is March 23, 14 days before the 32°F one. The freeze-free season lasts 244 days in a typical year, shorter than at 55% of the 339 Texas stations; it reaches 268 days one year in ten and falls short of 215 one year in ten. On average 50 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 14 days longer, to about April 1, and return around November 5. Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 56%.
