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.
Rainfall Return Levels
50 years, 1951 to 2004
A day with at least 87.2 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 327.9 mm (12.9 in) of rain is expected about once in 100 years.

Longer than the 50 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, 50 years of values from 1951 to 2004.
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: 309.9 mm (12.2 in) in 1994; 294.9 mm (11.6 in) in 1993; 265.7 mm (10.5 in) in 1977.
Station Changes
2 suspected
2 changes were suspected in the annual mean temperature of Phitsanulok/Sarit, at 1977 and 1998. Each is measured against neighbouring stations.
Relative to 4 neighbouring stations, the station's annual mean temperature from 1977 ran 0.3 C (0.5 F) lower than in the years before (likely change).
Relative to 4 neighbouring stations, the station's annual mean temperature from 1998 ran 0.4 C (0.8 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.
