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 Columbia Wb City falls on 13 April and the median first autumn frost on 19 October, which leaves a median of 190 days between them.

In 1920 to 1950 the median growing season was 198 days. That is 12 days more than in 1890 to 1919.

Fitted over all years, the growing season changes by +4.7 days per decade at this station.

Frost dates and growing season at Columbia Wb City
Measure	Median, all years	Earliest period (1890 to 1919)	Recent period (1920 to 1950)	Recent against earliest	Fitted trend
Last spring frost	13 April	16 April	11 April	5 days earlier	-1.9 days per decade
First autumn frost	19 October	15 October	25 October	10 days later	+2.8 days per decade
Growing days	190 days	186 days	198 days	12 days more	+4.7 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

61 years, 1890 to 1950

A day with at least 62.7 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 165.2 mm (6.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Columbia Wb City: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	62.7 mm (2.5 in)
5 years	81.9 mm (3.2 in)
10 years	97.4 mm (3.8 in)
25 years	120.8 mm (4.8 in)
50 years	141.5 mm (5.6 in)
100 years	165.2 mm (6.5 in)	Longer than the 61 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, 61 years of values from 1890 to 1950.

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: 167.9 mm (6.6 in) in 1918; 151.9 mm (6.0 in) in 1905; 121.7 mm (4.8 in) in 1928.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Columbia Wb City, at 1935. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1935 ran 0.1 C (0.3 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1935	+0.1	+0.3	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.
