A year with missing days can understate an extreme.

Rainfall Return Levels

30 years, 1965 to 1995

A day with at least 28.7 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 88.7 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Blomskog: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	28.7 mm (1.1 in)
5 years	37.2 mm (1.5 in)
10 years	45.1 mm (1.8 in)
25 years	58.6 mm (2.3 in)
50 years	71.9 mm (2.8 in)	Longer than the 30 years of record
100 years	88.7 mm (3.5 in)	Longer than the 30 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, 30 years of values from 1965 to 1995.

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: 74.2 mm (2.9 in) in 1988; 68.6 mm (2.7 in) in 1989; 48.0 mm (1.9 in) in 1965.
