'A sunshower, huh.' 'Huh?' 'There's an 81% chance of sun today, but in some areas there'll be sun showers.'
Literal
''Fox [possessive-の] bride-going is [confirmation-ね]'' ''Huh?'' ''Today [topic-は] 81% [possessive-の] probability [with-で] sunny is-[but-が], depending-on-place [locative-によっては] weather-rain is.''
A weather-and-folklore exchange. キツネの嫁入り ('fox's bride-going') is a charming folklore idiom for a sunshower — rain falling while the sun shines. The folklore connects the mysterious weather to the folkloric belief that foxes hold wedding ceremonies in such rain. 天気雨 ('weather rain') is the meteorological term for the same phenomenon. ~によっては ('depending on X') introduces a variable condition.
