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
81 years with a frost
Across 81 years with a frost, the median last spring frost at Colfax falls on 19 May and the median first autumn frost on 17 September, which leaves a median of 124 days between them.
In 1960 to 1993 the median growing season was 134 days. That is 29 days more than in 1893 to 1936.
Fitted over all years, the growing season changes by +5.9 days per decade at this station.

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
81 years, 1893 to 1993
A day with at least 27.4 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 55.1 mm (2.2 in) of rain is expected about once in 100 years.

Longer than the 81 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, 81 years of values from 1893 to 1993.
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: 50.8 mm (2.0 in) in 1955; 49.3 mm (1.9 in) in 1989; 47.5 mm (1.9 in) in 1897.

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.
