Was looking forward to something interesting coming up from France, but a band of light rain is likely it seems. Will watch as it moves ashore though.
Wind has sudden changed to the East after being light a variable for a few hours. Just had a gust up to 14 mph.
Temperature steady at 22.0°C. DP 17.9°C

Impressive looking cell, this one!

Cells now appearing over Sussex and the North Downs, heading West/WNW. Can see the cell from here in Emsworth.

Temperatures are comfortably around 31-33°C across most of inland Hampshire, Dorset and Somerset now. The atmosphere is 'loaded' now for development, you can see the SE has already started with plenty of altocumulus development in the past hour.
The fuse is ready to be lit. My bets are on surface based convergence zones for storm development that are setting up this afternoon. Salisbury plain, Bristol/Bath area eastwards, Exeter/Honiton and possibly over the South Downs are my picks for our area.

Still clear here and I can report that the solar noon sun genuinely has a string to it. Impressive for nearly two months past summer solstice!
32*C and hardly any wind will tend to have that effect .
Bang on 32°C here too and the wind has completely dropped. It feels borderline unbearable.
Dew point is beginning to rise again now, up to 19.6°C
-
31.5°C here, rising rapidly in the last half hour.
-
Reached 30°C here just now, which is an hour earlier than yesterday. RH and Dew points following that rise, so feeling very muggy.
Just taken a look at the models in regards to any storm developments and around here there is a cap present, once again, at around 29,000ft. Which is forecast to break once temperatures hit 31 or 32°C this afternoon. So possible storm developments to look forward too, if everything else comes into play.
Currently 30.2°C, winds E at 3mph.

I don't think I can remember such a hot period of weather that didn't produce some storms here. Looking at the charts, there's practically no surface based CAPE or Lift in the forecast, only MLCAPE, and that's nothing to shout about. This whole period of thunder risk is classed as 'Isolated'
I find it highly unusual. Zero rainfall as well!
Yeah, it really is surprising! With at least 2 days of excess heat, we tend to get at least an import, but nothing at the moment! As a kid, the 90s were my favourite time for storms. every summer there were at least a few nights with long lasting storms!
Tomorrow evening onwards look more promising for the south, though

Does the cap mean high pressure squeezing down the tops development ?
It works in the same way really! A cap is just a term used in weather to mean energy can only rise to a certain point, stopping any thunderstorm developments. They usually occur when the boundary layer (rising warm air) hits the colder inversion area (cap), basically preventing the energy from rising any further in the atmosphere. Todays cap has been sitting around 3-6,000ft across the south, thus not conductive for storm clouds which reach 30-40,000ft at times.
But as seen across Wales and the Midlands, the cap can be broken if conditions allow.

Cells firing around London and The Chilterns now. Latest Radar
.
Can confirm the pink circled shower is real...
Bit threatening, if you ask me...

Beautiful evening here, plenty of altocumulus building steadily now from the south. Also have a good view of the storm in Northern France now towards the SE. Quite a size on satellite!
Currently 26.8°C.
-
Northern France is exploding for the first time today. Interesting surface data from looking at the latest soundings over N France. I've got my eye on them.
As others have mentioned 'loaded gun' scenario over Southern England at the moment, but the cap remains.
Still hot. 30.1°C.
EDIT:-
Just complied my records locally of the top 5 temperatures and here they are:
34.4°C - 25 Jul 2019
34.1°C - 9 Aug 2020
33.9°C - 8 Aug 2020
33.3°C - 23 July 2019
33.3°C - 11 Aug 2020
These are now all within the past year. Pretty incredible.

Reached the dizzy heights of 33.3°C, that's the 5th day of temperatures above 30°C once again. Unheard off here.
The sea breeze has rushed back in over the past hour and had quite a drop in temperature. Most welcome!
Currently 29.0°C. Winds now SE at 11 mph.
-
Cooler nights compared to recent, with 16.9°C being the low at around 4.20am.
Expecting much higher temperatures today, possible threatening my highest every recorded temp of 34.4°C set last year. If the sea breeze stays back for long enough.
Currently 32.4°C with light NNE winds at 3 MPH. DP 19.0°C

I've just picked up a lightning strike!
I've been talking to a few people about the device I have and if mounted in a decent location, it is able to pick up strikes at farther distances over water.
Ecowitt? Been eyeing this up, if so!

Had a light rain shower here around 5.30pm. Was very light and evaporated instantly on contact with the ground.
After a high of 30.8°C (4th day in a row with 30+) its now cooler, but the temperature is rising again in the past hour. Same reason @Singularity mentioned above, around 5/6pm the sea breeze always cuts off and as a consequence, the winds have switched back to a light NE'ly.
Currently 25.3°C, Wind NE at 6 mph. Dew point beginning to rise as well at 18.9°C.

Broke another record last night for my station, recorded the maximum minimum temperature at 20.6°C which is 0.2°C above the old record.
Beautiful sunny day again today, temperatures were rising rapidly until around lunchtime when the sea breeze came flooding up from the channel. How I've missed it!
Currently 30.1°C Winds SSE at 15mph.
-
Still sitting above 20 here too, its actually still 24.2°C!
I've got a feeling my maximum minimum temperature is under threat.

Every summer it is so frustrating, why don’t TV forecasts predict the highest temperatures along the south coast when a NE or E breeze, both BBC and ITV are useless.
I think you really need a local meteorologist that understands local variations in climate. I know ITV Meridian's Holly Green does a good job at understanding local hot spots and regularly suggests Gosport area and Southern Hampshire as hotspots during the summer months. I believe she is currently on maternity. Sadly, national forecasts simply can't provide that level of detail in forecasts!

Still 29.2°C here at 8.45pm. Sweaty!
-
34.2°C at 5.10pm was the high today. Second warmest on record for my station and only 0.2°C off that record!
NE winds really do deliver for my location and the last 2 days are no exception. Incredible setup!
Sea breezes are expected here again tomorrow and for the rest of the week, cannot wait!
-
Just hit 34.1°C. 2nd highest recorded temperature at my station.
Incredible!
-
Slower climb with the temperature today compared to previous day's, but the rise is continuing and we are approaching yesterdays high of 33.9°C.
Currently 33.4°C.

Thorney Island is my nearest Met Office station at a little over 2 miles away. I maxed out at 33.9°C.
To see this site so far up the list during the summer months is truly exceptional.

These have shot up over Somerset in the past 15 minutes. Incredibly fast!
