A year with missing days can understate an extreme.

Rainfall Return Levels

38 years, 1948 to 1985

A day with at least 68.7 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 184.0 mm (7.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Harrisburg Disposal Pl: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	68.7 mm (2.7 in)
5 years	92.7 mm (3.6 in)
10 years	111.0 mm (4.4 in)
25 years	137.4 mm (5.4 in)
50 years	159.5 mm (6.3 in)	Longer than the 38 years of record
100 years	184.0 mm (7.2 in)	Longer than the 38 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, 38 years of values from 1948 to 1985.

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: 159.3 mm (6.3 in) in 1982; 139.7 mm (5.5 in) in 1977; 134.6 mm (5.3 in) in 1959.
