Our friend [waves], hello; high pressure, that's coming in.
As the high builds in notice it's like a big bubble building in like a big fat bloke going [elbows out - see pic] h-hurr, like that.
Friday was the day we probably marked a couple of days ago with a smiley face [gestures drawing one] on the calendar.
Look at that, that's a decent day. That's a picnic day. It's a day you say 'let's go to the beach.' Why not?
The high builds in and just sort of chills out the atmosphere.
Monday is OK, last minute shopping, you're gonna be fine I think, out and about.
Christmas Day potentially there could be a few showers. Not a washout, we're all inside with the board games.
We go into the weekend, you're still thinking about the ice-cream man? Well, you might still be.
This big lump of colour here and you look at the different colours and you think, 'well, Dan's been to the paint shop.'
Sadly, there's no video of this on the TVNZ website.
Christmas forecast from Dan Corbett "Santa will be in his board shorts but with a brolly in the boot" @MetService mastery!— Sam Wallace (@BreakfastSam) December 18, 2013
A mostly sunny Christmas expected
You can probably picture Santa as he came through, he probably had his board shorts on but he might have a raincoat in the back of his sleigh.
I think, if you're at the barbecue, wherever you might be, just plan for a few showers, but I think you keep your barbecue going, but of course, like me sometimes on rainy days back in the UK, you'd have your spatula like this, umbrella like that [see pic] and you'd be fine.
Christmas forecast looks good
MetService meterologist Daniel Corbett said the best conditions for thunder were south of Christchurch, where air from the land and the sea converged to give the storm an "extra lift".
"It's almost like having a big fire and someone throwing on a can of petrol."
Corbett was optimistic for a mostly dry Canterbury Christmas.
"If I was planning a barbecue, I wouldn't cancel it."
But he does advise telling your guests to bring a rain coat, just in case.
