Frost Dates in Arkansas

At the middle station of the 100 in Arkansas where a freeze comes every year, the last spring frost (50%) is March 28 and the first fall frost November 6, a freeze-free season of 224 days. The last frost is earliest at Stuttgart (Stuttgart 9 ESE, AR, March 11) and latest at Garfield (Seligman, MO, April 18), 38 days apart. The season runs from 185 days at Garfield to 250 at Stuttgart.

82 of these stations were also in NOAA's previous normals, for 1981–2010. Between the two, the median station's freeze-free season grew 5 days longer, with the last spring frost 3 days earlier and the first fall frost 2 days later; the season lengthened at 72 stations and shortened at 7. The two periods share twenty years, so the change reflects mostly 2011–2020 against 1981–1990.
