Some very high thicknesses across the UK at present, midnight Camborne HERE showing TT1000-500 at 568Dm and is even warmer across the Channel with Brest near 570Dm.

This is a fair bit warmer than yesterday.

Camborne would suggest max temps near 30C, but this should be attenuated by high cloud and later across the far southwest by a wind direction change into the southwest.

Mis to upper twenties again seem quite likely with places northwest of high ground likely to see the highest, especially across parts of the west country and Wales.

My own thoughts suggest the Thames Valley again may see the higest Temps. Certainly the higher cloud further west will detract from the high thickness values. Less breeze further east too.

Suggeest Northolt to Windsor to Bristol the highs at 26-27C - elsewhere 22-25 across England.

16.4°c here at 0830Z, with 6/8 skies and a 8 knot easterly breeze.

[Chris Alder]

If 27c is reached today that would make GFS a huge 5c out with its temp forecast today as its only got maxes of 22c! About 20.8c here but already very breezy and horribly milky sky so to be honest I can't see it warming up that much or much uv getting through!

[PJB]

21.8C here in Southbourne

09Z - Most Places in Thames Valley and London 1C+ up on Yesterday so far at 09Z

Jersey 21.7C
Gravesend 21.0C
Southampton O. C RTS 20.9C
St James PArk 20.9C
Northolt 20.9C
Bude 20.7C
Wisley 20.6C
Kew 20.5C
Otterbourne 20.3C

[Dave K]

At noon here 24.0 °C but feeling pleasantly fresh with a dewpoint of 9.2 °C.

[ChaserUK]

Currently 23.9c in town almost the same as this time yesterday - was expecting 29-30c today but that seems unlikely here now with some cirrus moving in from the W.

26.2C at Heathrow appears to have been the Max, so appears i did better today

Bit of a weird one as the synop max is actually 24.1 °C.

Dave thats because its reading the 1750 hourly obs from the day before when it was 26.2C so the 24.1C is correct

Ah yes I see..... I usually look at the actual synops but didn't tonight ... Clearly I was a litte too quick
