While in Tideswell, at 300m but below the inversion, we had fog all day

Hi, Norman,
Copley Lead Mill site day max 5.0C(nearly 8C down on the MetO site), just 400
metres away and 50 metres lower into the valley. Sunny all day here but the
Lead Mill screen sees no sun until February and creates its own inversions
anyway. Further into the inversion at Bishop Auckland we had to wait until
2pm for confirmation that the ground had thawed sufficiently for the match to
go ahead. Ken

We had a walk yesterday afternoon and at 350m we were in bright sunshine above
the inversion. In the dales the top of the fog was at about 320 metres. The
inversion was obviously at a higher level here than at Copley or perhaps there
was cold air pooling in the dales. That doesn't often happen because there's
usually a bit too much wind. Yesterday, though, the wind was pretty light. The
webcam at Harpur Hill, at about 375m on the outskirts of Buxton, showed fog
pretty well all day. Again, that might have been 'home grown' rather than the
product of some broadscale inversion. The webcams at the Cat & Fiddle (515m)
and Flash Bar (467m), both around 9 miles SW from here, showed crystal clear
air and strong sunshine all day. Who'd be a forecaster!
