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
36 years, 1933 to 1968
A day with at least 41.5 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 92.8 mm (3.7 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 36 years of values from 1933 to 1968.
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: 97.5 mm (3.8 in) in 1950; 68.8 mm (2.7 in) in 1947; 62.7 mm (2.5 in) in 1948.
