And I thought we invented Night Clouds!!! I spent my childhood thinking that this was why it got dark at night .... thanks to my dad ..... another local phrae is to say " it's a bit black over Bill's mothers" I have no idea who Bill is, or his mother for that matter, but it describes when a storm is approaching but is some way off...... and the clouds are "as black as a bag" We also refer to the position of the sun in (I think) November time, as "car crash light" ..... the kind of days where the sun is very low and usually orange/yellow light stops you from seeing properly.
