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 frost
Across 70 years with a frost, the median last spring frost at Mangum falls on 5 April and the median first autumn frost on 3 November, which leaves a median of 212 days between them.
In 1979 to 2010 the median growing season was 212 days. The two periods have the same number of growing days.
Fitted over all years, the growing season changes by -0.6 days per decade at this station.

Longer than the 88 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, 88 years of values from 1920 to 2022.
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: 181.1 mm (7.1 in) in 2018; 163.8 mm (6.4 in) in 1983; 156.2 mm (6.1 in) in 1923.
