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

60 years with a frost

Across 60 years with a frost, the median last spring frost at Priest Valley falls on 24 May and the median first autumn frost on 7 October, which leaves a median of 136 days between them.

In 1974 to 2011 the median growing season was 141 days. That is 17 days more than in 1933 to 1973.

Fitted over all years, the growing season changes by +4.4 days per decade at this station.

Frost dates and growing season at Priest Valley
Measure	Median, all years	Earliest period (1933 to 1973)	Recent period (1974 to 2011)	Recent against earliest	Fitted trend
Last spring frost	24 May	26 May	22 May	4 days earlier	-1.7 days per decade
First autumn frost	7 October	1 October	17 October	16 days later	+2.8 days per decade
Growing days	136 days	124 days	141 days	17 days more	+4.4 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

97 years, 1910 to 2010

A day with at least 52.3 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 123.6 mm (4.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Priest Valley: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	52.3 mm (2.1 in)
5 years	70.1 mm (2.8 in)
10 years	82.4 mm (3.2 in)
25 years	98.5 mm (3.9 in)
50 years	110.9 mm (4.4 in)
100 years	123.6 mm (4.9 in)	Longer than the 97 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, 97 years of values from 1910 to 2010.

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: 129.5 mm (5.1 in) in 1966; 128.3 mm (5.1 in) in 1995; 120.9 mm (4.8 in) in 1982.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Priest Valley, at 1976. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1976 ran 0.3 C (0.5 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1976	-0.3	-0.5	likely	5

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.
