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
76 years with a frost
Across 76 years with a frost, the median last spring frost at Maple Plain falls on 8 May and the median first autumn frost on 2 October, which leaves a median of 152 days between them.
In 1954 to 1984 the median growing season was 152 days. That is 5 days more than in 1894 to 1937.
Fitted over all years, the growing season changes by +0.5 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
83 years, 1894 to 1985
A day with at least 56.5 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 127.7 mm (5.0 in) of rain is expected about once in 100 years.

Longer than the 83 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, 83 years of values from 1894 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: 127.0 mm (5.0 in) in 1951; 120.7 mm (4.8 in) in 1902; 107.7 mm (4.2 in) in 1935.
Station Changes
1 suspected
