Oh, where did that come from? Thick fog just this minute rolled in from the sea, suddenly went all cold and murky here at the Harbour area. That is a bit of a jarring change after having been gloriously sunny and warm all day.

A weird fog has just rolled in and is starting to make it this far inland !

Very unusual given the temperature was at 25c an hour ago.

22.2c now with a dewpoint now up to 19c.

Very sticky...my usual view of the town has dissapeared.

EDIT, getting dark with lights on ! 

Heard the fog horn and thought why the hell is that on, then noticed the Sea fog had rolled in (about 7pm) to obscure the castle from my study window.  The second hottest September day in my 9 year record.  Maxed at 25.8 at 1.30pm.  Hottest September day at this station remains the epic 21 September 2006 with 26.6c.

I notice a narrow band of intense storms over Nofolk these have given 14mm of rain in a short time.

Temp here down to 14.9c as the cooler air rushes in from the west

It's crazy down here in Folkestone WI...one minute everyone was mellowing into a another very warm and sunny evening when all of a sudden a damp, dark monster from the sea suddenly turned day into night. People came out of their front doors wondering what had happened.

18.7c and calm after a max here of 25.7c (hottest September day here too since 21st September 2006). 

Yes.  Horn still droning but castle now in view.  There was a weird yellowish glow about it as a lobe drited closeby.  Expecting ghost pirates any moment!

It has caught us all out Ian. About 10 minutes before the arrival of the fog the atmoshere suddenly took on a very smoky look and damp feel as a light breeze at 5mph blew.

A pocket of humid air has obviously over ridden the relatively cool sea to create this event.

A noteworthy event and a huge switch in the matter of minutes. 

Evening 

A dry and very warm day with unbroken sunshine until the arrival of the dark English Channel fog bank just before 7pm. Max temperature today was 25.7c.

A very warm/hot day across Kent. I noticed Manston was recording 29.7c at 4pm. At the same time as Langdon Bay within viewing distance, 16 miles away, was recording a mere 22.8c.

The fog is now clearing into a mist with clear skies overhead.

Air 17.6c / Dew 17.0c

RH 93%

Wind SW 4 mph

Pressure 1009.5mb falling

Another baking hot day with clear blue skys and wall to wall sunshine

The last two days have felt like it was back in July with nearly the same temperatures

Ringwood,Hants had a max temp of 30.2c today and 29c yesterday pretty impressive for september.

Turned cool and cloudy about 6pm with a few spots of rain and wind came in from the sea. 12.8C now.
 

Patchy cloud 19c

Got to 29C today.
