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

23 years with a frost

Across 23 years with a frost, the median last spring frost at Gallatin 1W falls on 17 April and the median first autumn frost on 19 October, which leaves a median of 185 days between them.

Frost dates and growing season at Gallatin 1W
Measure	Median, all years	Earliest period	Recent period (1964 to 2022)	Recent against earliest	Fitted trend
Last spring frost	17 April	n/a	17 April	n/a	n/a
First autumn frost	19 October	n/a	19 October	n/a	n/a
Growing days	185 days	n/a	185 days	n/a	n/a

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

68 years, 1896 to 2022

A day with at least 71.1 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 209.2 mm (8.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Gallatin 1W: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	71.1 mm (2.8 in)
5 years	98.6 mm (3.9 in)
10 years	120.0 mm (4.7 in)
25 years	151.6 mm (6.0 in)
50 years	178.7 mm (7.0 in)
100 years	209.2 mm (8.2 in)	Longer than the 68 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, 68 years of values from 1896 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: 173.2 mm (6.8 in) in 2007; 172.7 mm (6.8 in) in 2008; 159.8 mm (6.3 in) in 2016.
