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

34 years, 1952 to 1985

A day with at least 32.0 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 69.6 mm (2.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Grada_Kraftverk: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.0 mm (1.3 in)
5 years	41.4 mm (1.6 in)
10 years	47.9 mm (1.9 in)
25 years	56.4 mm (2.2 in)
50 years	62.9 mm (2.5 in)	Longer than the 34 years of record
100 years	69.6 mm (2.7 in)	Longer than the 34 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, 34 years of values from 1952 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: 57.0 mm (2.2 in) in 1973; 56.7 mm (2.2 in) in 1954; 56.2 mm (2.2 in) in 1972.
