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

100 years, 1900 to 2007

A day with at least 53.1 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 177.9 mm (7.0 in) of rain is expected about once in 100 years.

50 years146.6 mm (5.8 in)
100 years177.9 mm (7.0 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 100 years of values from 1900 to 2007.

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: 275.3 mm (10.8 in) in 1998; 131.8 mm (5.2 in) in 1986; 122.9 mm (4.8 in) in 1926.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Sheboygan, at 1922. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1922 ran 0.4 C (0.7 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.
