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

79 years with a frost

Across 79 years with a frost, the median last spring frost at Harrisonville falls on 16 April and the median first autumn frost on 22 October, which leaves a median of 188 days between them.

In 1944 to 1979 the median growing season was 193 days. That is 8 days more than in 1894 to 1924.

Fitted over all years, the growing season changes by +1.2 days per decade at this station.

Frost dates and growing season at Harrisonville
Measure	Median, all years	Earliest period (1894 to 1924)	Recent period (1944 to 1979)	Recent against earliest	Fitted trend
Last spring frost	16 April	18 April	14 April	4 days earlier	-0.2 days per decade
First autumn frost	22 October	18 October	24 October	6 days later	+0.9 days per decade
Growing days	188 days	185 days	193 days	8 days more	+1.2 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

93 years, 1894 to 2017

A day with at least 66.9 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 173.5 mm (6.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Harrisonville: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	66.9 mm (2.6 in)
5 years	91.0 mm (3.6 in)
10 years	108.6 mm (4.3 in)
25 years	132.9 mm (5.2 in)
50 years	152.5 mm (6.0 in)
100 years	173.5 mm (6.8 in)	Longer than the 93 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 93 years of values from 1894 to 2017.

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: 193.5 mm (7.6 in) in 2017; 160.0 mm (6.3 in) in 1928; 148.8 mm (5.9 in) in 2007.
