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
77 years with a frost
Across 77 years with a frost, the median last spring frost at Fosston 1 E falls on 17 May and the median first autumn frost on 19 September, which leaves a median of 121 days between them.
In 1971 to 2008 the median growing season was 127 days. That is 12 days more than in 1910 to 1952.
Fitted over all years, the growing season changes by +2.0 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
82 years, 1910 to 2001
A day with at least 45.6 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 186.3 mm (7.3 in) of rain is expected about once in 100 years.

Longer than the 82 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, 82 years of values from 1910 to 2001.
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: 179.6 mm (7.1 in) in 1912; 152.4 mm (6.0 in) in 1950; 138.9 mm (5.5 in) in 1973.
Station Changes
2 suspected
2 changes were suspected in the annual mean temperature of Fosston 1 E, at 1942 and 1970. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1942 ran 0.4 C (0.7 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1970 ran 0.5 C (0.9 F) lower than in the years before (likely change).

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
