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.

Longer than the 73 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, 73 years of values from 1881 to 1983.
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: 95.0 mm (3.7 in) in 1975; 79.5 mm (3.1 in) in 1971; 79.0 mm (3.1 in) in 1945.
Station Changes
2 suspected
2 changes were suspected in the annual mean temperature of Brome, at 1918 and 1949. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1918 ran 0.3 C (0.5 F) lower than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1949 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.
