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.

Frost Dates and Growing Season

25 years with a frost

Across 25 years with a frost, the median last spring frost at Glady 1 N falls on 21 May and the median first autumn frost on 24 September, which leaves a median of 132 days between them.

Fitted over all years, the growing season changes by +13.8 days per decade at this station.

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

35 years, 1974 to 2009

A day with at least 54.3 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 111.0 mm (4.4 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, 35 years of values from 1974 to 2009.

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: 110.7 mm (4.4 in) in 1985; 90.7 mm (3.6 in) in 1991; 79.2 mm (3.1 in) in 1996.
