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.

Rainfall Return Levels

30 years, 1955 to 1986

A day with at least 111.8 mm (4.4 in) of rain is expected about once in 2 years. A day with at least 199.6 mm (7.9 in) of rain is expected about once in 100 years.

100 years199.6 mm (7.9 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 1955 to 1986.

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: 203.2 mm (8.0 in) in 1985; 158.8 mm (6.3 in) in 1956; 156.7 mm (6.2 in) in 1955.
