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 frostAcross 77 years with a frost, the median last spring frost at Des Arc falls on 21 March and the median first autumn frost on 7 November, which leaves a median of 229 days between them.
In 1993 to 2025 the median growing season was 244 days. That is 25 days more than in 1904 to 1971.
Fitted over all years, the growing season changes by +4.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1904 to 1971) | Recent period (1993 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 March | 26 March | 14 March | 12 days earlier | -2.0 days per decade |
| First autumn frost | 7 November | 3 November | 11 November | 8 days later | +2.6 days per decade |
| Growing days | 229 days | 219 days | 244 days | 25 days more | +4.6 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
82 years, 1904 to 2024A day with at least 84.4 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 183.3 mm (7.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 84.4 mm (3.3 in) | |
| 5 years | 111.0 mm (4.4 in) | |
| 10 years | 128.6 mm (5.1 in) | |
| 25 years | 150.7 mm (5.9 in) | |
| 50 years | 167.1 mm (6.6 in) | |
| 100 years | 183.3 mm (7.2 in) | 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 1904 to 2024.
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: 175.8 mm (6.9 in) in 1955; 165.1 mm (6.5 in) in 1988; 163.8 mm (6.4 in) in 2017.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Des Arc, at 1992 and 2017. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.2 C (0.4 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2017 ran 0.6 C (1.1 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1992 | -0.2 | -0.4 | possible | 5 |
| 2017 | +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.
Climate Twins
2009 to 2025 against 1961 to 1990Over 2009 to 2025, Des Arc had a mean temperature of 17.3 C (63.2 F) and 1,385.5 mm (54.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Cleveland (United States, 154 km away), Minter City (United States, 180 km away) and Arkansas Post (United States, 107 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Cleveland | United States | 154 km (96 mi) | 17.1 C (62.8 F) | 1,445.8 mm (56.9 in) | 0.44 |
| Minter City | United States | 180 km (112 mi) | 17.0 C (62.7 F) | 1,322.5 mm (52.1 in) | 0.49 |
| Arkansas Post | United States | 107 km (66 mi) | 17.3 C (63.1 F) | 1,329.5 mm (52.3 in) | 0.52 |
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.
