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
67 years with a frostAcross 67 years with a frost, the median last spring frost at Watford City falls on 21 May and the median first autumn frost on 18 September, which leaves a median of 120 days between them.
In 1959 to 2018 the median growing season was 120 days. That is 1 day more than in 1920 to 1950.
Fitted over all years, the growing season changes by +0.8 days per decade at this station.
| Measure | Median, all years | Earliest period (1920 to 1950) | Recent period (1959 to 2018) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 May | 23 May | 21 May | 2 days earlier | -0.4 days per decade |
| First autumn frost | 18 September | 17 September | 18 September | 1 day later | +0.4 days per decade |
| Growing days | 120 days | 119 days | 120 days | 1 day more | +0.8 days per decade |
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
74 years, 1912 to 2015A day with at least 37.4 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 93.7 mm (3.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 37.4 mm (1.5 in) | |
| 5 years | 50.6 mm (2.0 in) | |
| 10 years | 60.0 mm (2.4 in) | |
| 25 years | 72.8 mm (2.9 in) | |
| 50 years | 83.0 mm (3.3 in) | |
| 100 years | 93.7 mm (3.7 in) | Longer than the 74 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, 74 years of values from 1912 to 2015.
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: 85.1 mm (3.4 in) in 1965; 83.8 mm (3.3 in) in 1952; 77.5 mm (3.1 in) in 1929.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Watford City, at 1969 and 2001. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1969 ran 0.6 C (1.1 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2001 ran 0.6 C (1.1 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1969 | -0.6 | -1.1 | likely | 5 |
| 2001 | +0.6 | +1.1 | likely | 5 |
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.
