Each chart shows one value per year; the dot marks the record year. 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.

24 years with a frost
Across 24 years with a frost, the median last spring frost at Broadview falls on 18 May and the median first autumn frost on 17 September, which leaves a median of 123 days between them.

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
42 years, 1907 to 1990
A day with at least 31.1 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 65.4 mm (2.6 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, 42 years of values from 1907 to 1990.
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: 66.0 mm (2.6 in) in 1969; 53.8 mm (2.1 in) in 1967; 50.8 mm (2.0 in) in 1953.
