Although it was probably caused by the amount of jet washing I have done over last few days

It is that season. It's also very addictive. Had the hose/power lead been long enough, I'd have power washed a large swathe of the Peak District over the weekend.

And another half inch or so. Not forecast this time, completely unexpected. It was 23c yesterday....

Oh, for goodness sake! More???

Just to clarify, Monday will be so cold and abysmal, that when the low pressure system crosses the south, cold air from the north will get wrapped up in it. Heavy rain and evaporative cooling is likely to lead to some sleet and wet snow. Very unlikely to see disruptive snow. Hills are best, as usual.

Blimey, more snow, I've just managed to catch some sun and get a bit of colour!

How can it go from nearly 30 degrees to this ste in a week!

Looks like it might go back again in another week...

I mentioned this on another thread - I'm absolutely sure that in years gone by that we never got these enormous temperature swings over such short periods - seven days ago it was boiling, I came out of the house at 6.15 to drive to work and I was in a t shirt and it was lovely. Three days later the temperatures are down into low single figures and haven't made double figures all week - I'm still on my winter tyres and they're staying on. It's baltic out there.

This to me is the manifestation of this climate change thing, where I live at any rate. It's not wetter or drier. I can't tell if it's hotter or colder. What I do see is this yo-yo effect. I swear this is a recent (decade?) phenomenon - is it just me?

Quite easy to explain this yo-yo effect - at this time of year. The tilt in the Earth is changing, so the warmer air down south is being forced north, towards the colder air where we were. Occasionally the mixing is more severe - like the heat last week. That push of warm air then forces cooler air south.

The warming up of the Earth (what ever mechanism is causing it) will make these patterns more severe, because more energy is sloshing about.

This week's weather is slightly below average - last week's weather was way above average. So it's last week that was more of a shock, and that's what is causing this week's shock to our systems.

2 years ago (to the day), it snowed in the south.

Ha - same phenomenon being talked about on NW - and this came up from April 1945. Top right paragraph shows it was similar then, with some warmth, then something colder than we're expecting.

I can't confirm or deny what you say, but I bloody hate it. I got out of my car the other day and it was 50/50 whether I'd need a jacket or tshirt... I went for the jacket and it absolutely persisted down before I'd walked where I was going.

On the way home, I nearly had to carry the jacket, it was boiling.

Leaving the house shouldn't need a small suitcase to cover all weather options in the day.

What would be your best guess for weather in London over the 7th May bank holiday weekend?

There is an old adage, if you don't like the weather just wait 5 minutes....it's changeable and has been for a long time.

One of the models is offering this for Monday morning...

[Puggit]

Snowfall looking less likely, but by no means impossible tomorrow morning. Thames Valley and northern M25 section most likely. So Chilterns would be my bet if it happens.

Heavy and prolonged rain will cause local flooding issues.

You're kidding right?

I've been in shorts for 2 weeks!
