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

47 years with a frost

Across 47 years with a frost, the median last spring frost at Pullman Exp STN falls on 30 April and the median first autumn frost on 13 October, which leaves a median of 163 days between them.

Fitted over all years, the growing season changes by +8.3 days per decade at this station.

First autumn frost13 Octobern/a18 Octobern/a+4.0 days per decade
Growing days163 daysn/a176 daysn/a+8.3 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

42 years, 1894 to 1953

A day with at least 27.1 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 66.5 mm (2.6 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 42 years of values from 1894 to 1953.

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: 59.9 mm (2.4 in) in 1906; 53.3 mm (2.1 in) in 1902; 45.7 mm (1.8 in) in 1913.
