Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

94 years with a frost

Across 94 years with a frost, the median last spring frost at Atchison falls on 14 April and the median first autumn frost on 21 October, which leaves a median of 190 days between them.

In 1976 to 2008 the median growing season was 197 days. That is 9 days more than in 1893 to 1934.

Fitted over all years, the growing season changes by +1.4 days per decade at this station.

Frost dates and growing season at Atchison
Measure	Median, all years	Earliest period (1893 to 1934)	Recent period (1976 to 2008)	Recent against earliest	Fitted trend
Last spring frost	14 April	14 April	9 April	5 days earlier	-0.7 days per decade
First autumn frost	21 October	16 October	23 October	7 days later	+0.7 days per decade
Growing days	190 days	188 days	197 days	9 days more	+1.4 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

122 years, 1897 to 2025

A day with at least 69.4 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 131.1 mm (5.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Atchison: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	69.4 mm (2.7 in)
5 years	88.5 mm (3.5 in)
10 years	100.0 mm (3.9 in)
25 years	113.4 mm (4.5 in)
50 years	122.6 mm (4.8 in)
100 years	131.1 mm (5.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 122 years of values from 1897 to 2025.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 128.8 mm (5.1 in) in 1958; 116.1 mm (4.6 in) in 1961; 114.3 mm (4.5 in) in 1909.
