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
103 years with a frost
Across 103 years with a frost, the median last spring frost at Middletown 4 W falls on 29 April and the median first autumn frost on 10 October, which leaves a median of 165 days between them.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 110 years of values from 1869 to 1996.
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: 196.9 mm (7.8 in) in 1992; 181.9 mm (7.2 in) in 1869; 134.6 mm (5.3 in) in 1982.
