A decade or so ago I would have looked at the forthcoming charts showing
high pressure on the near continent with a slack southerly flow and
almost guaranteed widespread fogs. However, so far the forecasts have
hardly mentioned fog(s).

Strong indication of fairly dense fog formation over England and Wales on
Sunday night.
TAFs trending towards this, e.g. Birmingham

More is expected tonight too compared to last night, more especially
in the
SW,
e.g Bristol

The trapped aerosols likely to further aid fog formation tomorrow.

Jon.

The murk has thickened to fog in Chalfont St Giles during the past hour.
Currently (2230z) around 800 metres.
