I suspect they have inches and cm muddled!

I thought we were looking at the real cold air not arriving until Wednesday afternoon though. Cooler on Tuesday is a start.

That's why the forecast for Sunday/Monday really doesn't matter too much. Trends...

It looked like parts of Brighton were gritted first thing this morning. Madness.

Yes 2010 was the last time. I will be making the journey home between Portslade and Eastbourne this evening via the A27. This takes me up over the downs so should start to get an idea of how things are looking as move away from the coast and higher briefly.

Without doubt a nowcast situation. I've always doubted a significant snow event from this and the models are behaving the way they always do in this sort of situation. I suspect snow will be confined to upland areas across the South East, with some local exceptions based on precip intensity. And the model runs I've woken to this morning are very nice if you like the cold.

Things starting to fire over North West France right now. This could be round 2.

Pleased to say confirmed that this is not the case, although the centre has been closed and evacuated.

Reports now coming in that the roof on a childens adventure play centre in Eastbourne has possibly collapsed as a result of heavy rain. Worrying... but hopefully not as bad as it sounds. I'm not joking when I say that there has been some really serious rainfall in Sussex so far today. I suspect we're talking 3-5 inches in 12-hours, before anything that comes this afternoon.

Some parts already do have serious flooding problems. I think there is a bit of an *if* on storms later though. I'm not so sure about that.

All flying displays cancelled today.

And at last... the rain has finally stopped and rumble becoming more distant. Sky slowly brightening. All eyes to Northern France then.

Almost 9-hours of continuous thunder and lightning now on the Sussex coast. Incredible.

What incredible weather on the Sussex coast. Thunder and lightning almost continuously since 3am this morning (yes it's still going right now) with just a brief break between say 6am and 7.30am. Huge rainfall totals without a doubt. I suspect we're approaching (or possibly even exceeding) 75mm in a 12-hour period. Rain is persistent and heavy, often utterly torrential. Surface water flooding is almost a certainty in places - indeed latest travel news confirms numerous instances of flooded roads, many of them major A-roads. It now looks like a quiet period later, before further storms later this afternoon and then possibly again tomorrow.
