I was sitting outside taking the air at 6.15pm today watching a group of
soaring birds thermalling away - all turning in the same direction and
maintaining a good lookout as they should. They were climbing very well
without flapping of wings. Moments later there was a sudden gust of wind to
28mph with a shower of small foliage from nearby trees. The temperature
started to fall quickly, the wind shifted from NNE to ENE and the relative
humidity rose from 44% to 60% in 15 minutes. The barograph trace bottomed
out. I can only assume that this was a rather late or even second sea breeze
front passing through as the temperature had already been falling for an
hour.
Tmax 28.1º today with the RH down to a very pleasant 33%

That sounds rather similar to what happened here. At 18Z the
temperature was 27°C with a light and variable wind and a few minutes
later the wind became a rather gusty ENE'ly, about force 4, with the
temperature falling 9° in an hour. It has now largely levelled out at
about 12 °C. There was a noticeable increase in the haze with the low
sun looking very red whereas during the day the sky had been a hard
deep blue and the sun very bright.

It happened about 16:15z here in Leysdown (north Kent) - there was a sudden
gust of wind and the temperature fell sharply, 6C in the half hour between
16 and 16:30z. There was also an appearance of some cloud, although the sun
came out again by 17z.

The hourly summaries for Southend show it well:

Interestingly, the MetO picked up on it rather well, showing the wind
veering and temperature dropping markedly between 15z and 18z for here. GFS
had a similar switch but a smaller drop in temperature.

----------------------
Same here, dropped from 27C to 17C in the hour between 17.30 and 18.30.
Suprisingly windy here this morning considering the lack of isobars but
there does seem to be some disturbances running down in the flow.
