My Gran loved all sorts of sayings, like, “Don’t throw the baby out with the bath water”, “Let the dog see the rabbit” or “A watched pot never boils.”

But she particularly loved sky-based sayings: “There’s enough blue sky to make a pair of sailor’s trousers” or “Red sky at night, shepherds’ delight, red sky in the morning, shepherds’ warning” (which I still consider a reliable weather forecast).

I wonder what she’d have made of today’s yellow sky?

London’s streets were a hue I’ve never seen before as dust from forest fires in southern Europe and Africa swept into the city.

Naturally, some new tics swept in too:

“Red sky at night, lamp-post’s delight. Yellow sky in the morning, TV aerial’s warning.”

“There’s enough yellow sky to make Boris Johnson a pair of pants.”

“Lamp-post, the sky is as orange as your light.”

“The lamp-post is impersonating a shepherd again.”

“Sleep tight lamp-post, don’t let the storm dampen your light.”

I can hear the promised storm starting to take hold, with the wind and rain battering the street outside.

I’m going to sleep now and hope for calmer, clearer skies tomorrow, for lamp-posts and for everyone else.
