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

46 years with a frost

Across 46 years with a frost, the median last spring frost at Blountstown 2 SE falls on 3 March and the median first autumn frost on 16 November, which leaves a median of 257 days between them.

Fitted over all years, the growing season changes by -0.3 days per decade at this station.

Frost dates and growing season at Blountstown 2 SE
Measure	Median, all years	Earliest period	Recent period (1943 to 1981)	Recent against earliest	Fitted trend
Last spring frost	3 March	n/a	2 March	n/a	+0.6 days per decade
First autumn frost	16 November	n/a	14 November	n/a	+0.4 days per decade
Growing days	257 days	n/a	258 days	n/a	-0.3 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

56 years, 1921 to 1981

A day with at least 96.0 mm (3.8 in) of rain is expected about once in 2 years. A day with at least 281.4 mm (11.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Blountstown 2 SE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	96.0 mm (3.8 in)
5 years	133.7 mm (5.3 in)
10 years	162.9 mm (6.4 in)
25 years	205.3 mm (8.1 in)
50 years	241.3 mm (9.5 in)
100 years	281.4 mm (11.1 in)	Longer than the 56 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, 56 years of values from 1921 to 1981.

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: 254.0 mm (10.0 in) in 1926; 219.2 mm (8.6 in) in 1972; 202.7 mm (8.0 in) in 1932.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Blountstown 2 SE, at 1973. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1973 ran 0.3 C (0.5 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Blountstown 2 SE, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1973	+0.3	+0.5	possible	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.
