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

69 years with a frost

Across 69 years with a frost, the median last spring frost at Sloan 3 S falls on 11 April and the median first autumn frost on 31 October, which leaves a median of 202 days between them.

In 1941 to 1980 the median growing season was 199 days. That is 7 days fewer than in 1894 to 1930.

Fitted over all years, the growing season changes by -2.5 days per decade at this station.

Growing days	202 days	206 days	199 days	7 days fewer	-2.5 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

84 years, 1894 to 1980

A day with at least 76.7 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 186.3 mm (7.3 in) of rain is expected about once in 100 years.

Expected about once in	A day with at least	Note
2 years	76.7 mm (3.0 in)
5 years	100.4 mm (4.0 in)
10 years	118.2 mm (4.7 in)
25 years	143.2 mm (5.6 in)
50 years	163.8 mm (6.4 in)
100 years	186.3 mm (7.3 in)	Longer than the 84 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, 84 years of values from 1894 to 1980.

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: 170.2 mm (6.7 in) in 1928; 164.8 mm (6.5 in) in 1899; 157.7 mm (6.2 in) in 1960.
