Graham, it was all a bit ambiguous here as there was no rain and we had
sunny intervals all day. But looking at the temperature and DPs, it
seems that the CF possibly went through about 14:50 though there was no
change in wind direction, or really any change in anything for that matter.

Anyway, what stuck out today was the very high UV - I recorded a UV
Index of 9.5 at 13:28. That's the highest this year by a reasonably
large margin and the highest since a UV of 10.0 on the 14th July 2014,
though many days have come close.

I am presuming this high UV occurred just before the CF went through and
confirms what we already know - very high UV levels are often found in
warm sectors.
