NOAA 1991–2020 freeze normals
Frost Dates in Missouri
Last and first frost at the 151 NOAA stations behind this site's Missouri pages.
At the middle station of the 151 in Missouri where a freeze comes every year, the last spring frost (50%) is April 11 and the first fall frost October 24, a freeze-free season of 194 days. The last frost is earliest at Caruthersville (Caruthersville, MO, March 24) and latest at New Haven (Rosebud, MO, April 27), 34 days apart. The season runs from 164 days at Sullivan to 230 at Caruthersville.
128 of these stations were also in NOAA's previous normals, for 1981–2010. Between the two, the median station's freeze-free season grew 6 days longer, with the last spring frost 2 days earlier and the first fall frost 4 days later; the season lengthened at 110 stations and shortened at 9. The two periods share twenty years, so the change reflects mostly 2011–2020 against 1981–1990.
