Another foggy day in London town this Sunday morning, and as it was for most of yesterday. It’s also foggy down here in Devon as well, but I don’t think Ira Gershwin’s lyrics could be stretched to include the words “in Devon too”.
“A Foggy Day”
A foggy day in London Town
Had me low and had me down
I viewed the morning with alarm
The British Museum had lost its charm
How long, I wondered, could this thing last?
But the age of miracles hadn’t passed,
For, suddenly, I saw you there
And through foggy London Town
The sun was shining everywhere.
It’s obvious to anyone that ever wrote a TAF that there must have been some sort of GRADU 4000 SKC in the TAF for the day that Gershwin’s lyrics were describing – I seem to remember that you call also use the term RAPID, which might have been an even more appropriate way of picturing the last line. Excuse the contours in the next image, they are far too smoothed as you can see.
I’m struggling at the moment to find much in the way of thick fog around London to justify the title because much of it has now cleared as you can see this plot of Heathrow observations.
