There are indications it could turn thundery in the Home Counties tomorrow as the cold front presently over the NW wiggles its way reluctantly SE, then stalls. This system then gets blown east by a briefly re-invigorated jet stream on Tuesday and Wednesday before high pressure is predicted to ridge up from the south once more, giving most of us a return to balmy autumn warmth for the rest of the week.

Today's heavy underlay of clag obscuring what's more importantly going on weatherwise has finally resolved my decision to postpone the two-mile ride down to Penge St Sprees with the appearance of lightning strikes in a line stretching from the Solent to Amersham, and the arrival of large spots of rain in the past few minutes. In more usual British circumstances thick stratus at lower levels (it was foggy earlier) denotes conditions inimical to convection, which needs such cloud to break up to allow the sun to get to work at ground level, but on this occasion (once more) the thunderstorm-triggering convection is happening at higher levels independent of ground heating, and I imagine there must be some impressive altocumulus castellanus obscured from view encroaching from the south west.
The temperature is a close 21C, with hardly a leaf stirring. Showers are forecast for tomorrow too, but skies will be easier to read before taking a plunge, and it will be cooler, too.

The forecasts today have been varied and largely wrong for my location. The movement of the rain bearing cloud has evidently been difficult to sort out in terms of timing, location and propensity to dump. Can't say I'm sorry that the morning forecast of rain was wrong as the bus to the shops was 30 mins late... Currently it's supposed to be chucking down, but I think that's more likely later on so I'll go and rake up the grass clippings before it arrives. A grey day but warm.
Tomorrow has also changed significantly a couple of times, so I don't know if I'll get drenched going to meet my friend for coffee in the morning or not.

Beautiful shot of the very long and dramatic shelf cloud accompanying yesterday's elevated thundery trough sent in on UKWW:
Temperatures back to where they "should" be today, maxing around 17C - quite a shock to the system on going out earlier!
You have to scroll down to JonathanW's post to see this and another shot - apologies for not realising that - just click on the image for its enlargement.
