If you look at the following image (maybe needs registration - but free)
there appears to be a lot of dust over the western North Sea, clearly
visible to the NE of the cloud sheet:

The large bank of fog over and north of the Shetland Islands is also a
notable feature of the image.

I am glad that someone has pointed this bank of fog out. It's been
remarkable watching it drift SW over the past 36 hours. I have never seen
one travel such a distance and persist for so long.

That may well be a reflection of the absence of late-spring
anticyclonic northeasterlies over the last 5 or 6 years. My reaction
was: ... about time ... Lerwick has had very nearly 150 hours of
sunshine in the last 15 days. The absence of haar along North Sea
coasts so far during this spell has similarly caught the eye. Maybe
that is also about to change.
