Having recently come to live in Oswestry in Shropshire, I'm told by locals

As a complete and utter novice in these matters I hazard a guess that
it refers to showery activity that runs down over Cheshire on a NWly.
That,anyway, is when I think I have heard the expression used.
Watching the forum rather anxiously......
