Frost risk by date in Belleville

Half of springs at Blue Mountain Dam, AR see their last 32°F night by March 31; only one in ten is past it by March 12, 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 11 20%, and after April 17 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 41% of the 105 Arkansas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 1 in half of years, as early as October 18 one year in ten, and holds off past November 17 one year in ten. A hard freeze of 28°F follows 11 days later, around November 12; in spring the one-in-ten date for 28°F is April 4, 13 days before the 32°F one. The freeze-free season lasts 215 days in a typical year, shorter than at 64% of the 105 Arkansas stations; it reaches 238 days one year in ten and falls short of 193 one year in ten. On average 71 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 12 days longer, to about April 12, and return around October 23. Severe cold of 16°F or below comes in 94% of winters, usually between December 29 and February 3.
