This is the second consecutive day with an identifiable Heat Low over southern England. Yesterday's (Sat.) produced a marked westerly here which died out early evening. Today's low is somewhat less marked and there is a light N'ly but I wouldn't bet against a sea breeze from the south coast penetrating as far as here temporarily (40 miles). It does happen from time to time. Max temps on both days 31°C.
Tudor, unless my ageing eyes are deceiving me, a tiny heat low formed
over Exeter this afternoon. I was looking at the satellite images and
you can detect an anti-clockwise rotation to the clump of cloud stuck
over the city.
We're right on the edge of it here and the sky all around is clear. If
it wasn't a heat low then maybe sea breezes were responsible for the
rotation?

It's happened again! See this: a href="http://www.xcweather.co.uk/GB/observations"/a
Here at the moment (4.45 pm) and for a lot of the day the wind has been variable with 7/8 Cu med and Sc cugen. Rather gloomy and still. Despite the cloud the max so far is 28.2°C.
PS - I bet your eyes aren't as aged as mine.

Certainly seems to be a heat low http://meteocentre.com/analysis/map-...r&size=lar ge
Similar sort of circulation over Devon & Cornwall. S wind over most of Devon (away from the north coast.) Quite strong & gusty N wind across Cornwall, on both offshore & onshore coasts.

There's been a heat low over south Wales over the past couple of afternoons and evenings. In fact, it has been occurring quite often in the past month. It's tricky to pick out as there aren't any official observations inland between Cardiff on the coast and Sennybridge and Shobdon/Hereford to the north. If you look at other sources (WOW, Wunderground) you can easily make out the relatively lower pressure. Also, observation of wind direction at my location is very revealing - with some quite marked reversals during the day. You can also pick out low level convergence by studying animations of visible satellite imagery,
