Frost risk by date in Sheridan

Half of springs at Sheridan, AR see their last 32°F night by April 1; only one in ten is past it by March 11, and one in ten still has one after April 17. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 10 20%, and after April 17 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 65% of the 105 Arkansas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 3 in half of years, as early as October 20 one year in ten, and holds off past November 20 one year in ten. A hard freeze of 28°F follows 12 days later, around November 15; in spring the one-in-ten date for 28°F is April 6, 11 days before the 32°F one. The freeze-free season lasts 218 days in a typical year, shorter than at 60% of the 105 Arkansas stations; it reaches 243 days one year in ten and falls short of 197 one year in ten. On average 74 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 10 days longer, to about April 11, and return around October 26. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 83%.
