Frost risk by date in Vaiden

Half of springs at Winona 5 E, MS see their last 32°F night by April 7; only one in ten is past it by March 22, and one in ten still has one after April 24. Planting tender crops after April 14 leaves a 30% risk of a frost on them, after April 17 20%, and after April 24 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 71% of the 96 Mississippi stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 29 in half of years, as early as October 16 one year in ten, and holds off past November 11 one year in ten. A hard freeze of 28°F follows 9 days later, around November 7; in spring the one-in-ten date for 28°F is April 11, 13 days before the 32°F one. The freeze-free season lasts 203 days in a typical year, shorter than at 98% of the 96 Mississippi stations; it reaches 225 days one year in ten and falls short of 184 one year in ten. On average 81 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 19, and return around October 21. Severe cold of 16°F or below comes in 91% of winters, usually between December 31 and February 5.
