Ireland has a curious expression whereby this weather is used to mean “these days”. It normally occurs at the end of a clause or sentence, though it doesn’t have to. It’s a very colloquial phrase, more often heard than seen. But it appears sometimes in speechlike prose, such as these examples from the Irish chatroom boards.ie:
(1) He’s a sad man this weather.
(2) what coolant temp are you logging this weather?
(3) Wouldn’t imagine their stock was exactly flying out the door this weather.
(4) Hi, anyone else struggling with tacky paint this weather?
