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 at Clinton Forestry HQ
Measure	Median, all years	Earliest period	Recent period (1940 to 1974)	Recent against earliest	Fitted trend
Last spring frost	16 March	n/a	22 March	n/a	+2.3 days per decade
First autumn frost	9 November	n/a	4 November	n/a	-0.9 days per decade
Growing days	237 days	n/a	230 days	n/a	-3.2 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.

Expected about once in	A day with at least	Note
2 years	100.9 mm (4.0 in)
5 years	140.4 mm (5.5 in)
10 years	170.4 mm (6.7 in)
25 years	213.4 mm (8.4 in)
50 years	249.4 mm (9.8 in)
100 years	289.0 mm (11.4 in)	Longer than the 82 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, 82 years of values from 1895 to 2013.

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: 249.4 mm (9.8 in) in 1964; 228.6 mm (9.0 in) in 1983; 216.9 mm (8.5 in) in 1982.

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
