There's a good analysis here from the BBC about what's happening early next week http://www.bbc.co.uk/weather/feeds/30824978?ns_mchannel=social&ns_campaign=bbc_weather&ns_source=twitter&ns_linkname=news_central
Notice how they mention the front coming off the Atlantic probably won't have enough 'energy' to displace the cold air and allow mild air through.
Last night was not fun! Got barely any sleep due to all the thunder and lightning between 3 and 6 am!
Looks like we're about to enter a different 'phase' of winter soon according to the model output, exciting times ahead
Given the reports of snow in places in like Pembroke and Llanelli, I'd say it's pretty likely to see some flakes (though probably nothing substantial) in the Cardiff area but not until later this evening. I may be wrong though.
Interesting times ahead, such a mild and wet winter so far and now there are some signs of a change afoot with different air-masses having increasing influence near or over the UK.
I'm a bit sceptical about the whole '100% rain away from northern high ground' scenario that's being worshipped in the model thread. More of a mixture of rain, sleet and snow even in the south IMHO.
Today was my perfect day weatherwise i.e. mostly sunny with temps in the low twenties. I do like the sun but the heat is too much as I work in a warehouse, 23-24C suits me fine
