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

22 years with a frost

Across 22 years with a frost, the median last spring frost at Colfax falls on 15 March and the median first autumn frost on 9 November, which leaves a median of 234 days between them.

Frost dates and growing season at Colfax
Measure	Median, all years	Earliest period	Recent period (1948 to 2010)	Recent against earliest	Fitted trend
Last spring frost	15 March	n/a	15 March	n/a	n/a
First autumn frost	9 November	n/a	9 November	n/a	n/a
Growing days	234 days	n/a	234 days	n/a	n/a

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

42 years, 1937 to 2010

A day with at least 102.8 mm (4.0 in) of rain is expected about once in 2 years. A day with at least 310.8 mm (12.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Colfax: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	102.8 mm (4.0 in)
5 years	147.7 mm (5.8 in)
10 years	181.4 mm (7.1 in)
25 years	228.9 mm (9.0 in)
50 years	268.1 mm (10.6 in)	Longer than the 42 years of record
100 years	310.8 mm (12.2 in)	Longer than the 42 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, 42 years of values from 1937 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: 268.0 mm (10.6 in) in 2006; 222.5 mm (8.8 in) in 1953; 222.5 mm (8.8 in) in 1966.
