A day with at least 19.7 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 56.3 mm (2.2 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 1963 to 2025.

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: 50.8 mm (2.0 in) in 1997; 46.2 mm (1.8 in) in 1971; 36.8 mm (1.4 in) in 1982.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Bitter Creek 4 NE, at 1980 and 2020. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1980 ran 0.5 C (0.9 F) higher than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2020 ran 0.3 C (0.5 F) lower than in the years before (possible 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.

Climate Twins

1999 to 2025 against 1961 to 1990

Over 1999 to 2025, Bitter Creek 4 NE had a mean temperature of 6.8 C (44.2 F) and 153.9 mm (6.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Muddy Gap (United States, 123 km away), Gardiner (United States, 422 km away) and Pathfinder Dam (United States, 168 km away).

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
