Pet day

Heard in Wexford

An isollated day of fine weather during a spell of bad weather.

In use

Noah, it's been raining for 40 days and 40 nights! Don't worry, I'm sure we'll get a pet day soon.

Posh English

Noah, it has precipitated for forty days and forty nights! Fear not, I am confident a solitary day of clement weather shall be granted us presently.
