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

48 years with a frost

Across 48 years with a frost, the median last spring frost at Greensboro falls on 9 April and the median first autumn frost on 2 November, which leaves a median of 206 days between them.

Fitted over all years, the growing season changes by -0.5 days per decade at this station.

Frost dates and growing season at Greensboro
Measure	Median, all years	Earliest period	Recent period (1915 to 1945)	Recent against earliest	Fitted trend
Last spring frost	9 April	n/a	10 April	n/a	-0.5 days per decade
First autumn frost	2 November	n/a	1 November	n/a	-1.0 days per decade
Growing days	206 days	n/a	205 days	n/a	-0.5 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

30 years, 1903 to 1932

A day with at least 71.3 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 133.2 mm (5.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Greensboro: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	71.3 mm (2.8 in)
5 years	91.4 mm (3.6 in)
10 years	103.1 mm (4.1 in)
25 years	116.4 mm (4.6 in)
50 years	125.2 mm (4.9 in)	Longer than the 30 years of record
100 years	133.2 mm (5.2 in)	Longer than the 30 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, 30 years of values from 1903 to 1932.

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: 112.3 mm (4.4 in) in 1916; 111.0 mm (4.4 in) in 1932; 110.5 mm (4.4 in) in 1908.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Greensboro, at 1905. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1905 ran 0.4 C (0.8 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Greensboro, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1905	+0.4	+0.8	likely	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.
