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

41 years with a frost

Across 41 years with a frost, the median last spring frost at Henryville Sf falls on 29 April and the median first autumn frost on 7 October, which leaves a median of 159 days between them.

Fitted over all years, the growing season changes by -0.8 days per decade at this station.

Frost dates and growing season at Henryville Sf
Measure	Median, all years	Earliest period	Recent period (1934 to 1968)	Recent against earliest	Fitted trend
Last spring frost	29 April	n/a	2 May	n/a	+1.0 days per decade
First autumn frost	7 October	n/a	6 October	n/a	+0.2 days per decade
Growing days	159 days	n/a	158 days	n/a	-0.8 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

46 years, 1913 to 1970

A day with at least 62.2 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 149.7 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Henryville Sf: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	62.2 mm (2.4 in)
5 years	81.6 mm (3.2 in)
10 years	95.9 mm (3.8 in)
25 years	115.9 mm (4.6 in)
50 years	132.2 mm (5.2 in)	Longer than the 46 years of record
100 years	149.7 mm (5.9 in)	Longer than the 46 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, 46 years of values from 1913 to 1970.

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: 135.1 mm (5.3 in) in 1930; 126.7 mm (5.0 in) in 1960; 113.0 mm (4.4 in) in 1964.
