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
70 years with a frostAcross 70 years with a frost, the median last spring frost at Kewanee 1E falls on 24 April and the median first autumn frost on 12 October, which leaves a median of 171 days between them.
In 1996 to 2025 the median growing season was 174 days. That is 4 days more than in 1940 to 1977.
Fitted over all years, the growing season changes by +1.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1940 to 1977) | Recent period (1996 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 24 April | 25 April | 23 April | 2 days earlier | -0.4 days per decade |
| First autumn frost | 12 October | 12 October | 15 October | 3 days later | +0.7 days per decade |
| Growing days | 171 days | 170 days | 174 days | 4 days more | +1.2 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
72 years, 1940 to 2025A day with at least 67.8 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 126.7 mm (5.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 67.8 mm (2.7 in) | |
| 5 years | 85.4 mm (3.4 in) | |
| 10 years | 96.3 mm (3.8 in) | |
| 25 years | 109.2 mm (4.3 in) | |
| 50 years | 118.2 mm (4.7 in) | |
| 100 years | 126.7 mm (5.0 in) | Longer than the 72 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, 72 years of values from 1940 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: 137.4 mm (5.4 in) in 1954; 120.7 mm (4.8 in) in 2013; 111.8 mm (4.4 in) in 1969.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Kewanee 1E, at 1998 and 2017. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1998 ran 0.4 C (0.7 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2017 ran 0.3 C (0.5 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1998 | -0.4 | -0.7 | likely | 5 |
| 2017 | +0.3 | +0.5 | 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
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Kewanee 1E had a mean temperature of 9.8 C (49.7 F) and 974.1 mm (38.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are W Lafayette 6 NW (United States, 259 km away), Lafayette 8 S (United States, 273 km away) and Watseka Public Works (United States, 188 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| W Lafayette 6 NW | United States | 259 km (161 mi) | 9.9 C (49.9 F) | 919.3 mm (36.2 in) | 0.62 |
| Lafayette 8 S | United States | 273 km (170 mi) | 9.9 C (49.9 F) | 916.0 mm (36.1 in) | 0.63 |
| Watseka Public Works | United States | 188 km (117 mi) | 9.9 C (49.9 F) | 1,035.2 mm (40.8 in) | 0.64 |
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.
