One storm after another, trees down everywhere, power flickering on and off constantly, garden totally destroyed. Not sure I can handle any more but apparently it's going to carry on in to the new year.
(Sorry, I'm not OYBBK but could have a try at this one) I think it's something to do with the really cold weather that the East coast of the US/Canada have had together with a really strong jet stream at the moment. The strong jet stream which is right over the UK at the moment, is bringing a lot of the stormy weather in our direction, so we're getting one storm after another coming in from the West. From what I've seen (the netweather website have a 'jetstream forecast'), I think the jet stream isn't so strong towards the end of next week and toddles off to the south of us, so it gives colder weather a chance to come in.

UK Outlook for Sunday 12 Jan 2014 to Sunday 26 Jan 2014:
Current indications suggest the unsettled start to January is more likely than not to persist through the middle to latter part of the month. This would mean spells of dull, wet and windy weather alternating with brighter but colder and showery periods, including some wintry showers. Some signs are also emerging suggesting temperatures being less mild in general terms than the last couple of weeks, and perhaps even significantly colder late in the month.
So possibly a change is a-coming (and hopefully I've got some of the above right!)
There seem to be a lot of factors when it comes to the weather, some of which forecasters are only just beginning to understand. It seems to be when these things come together and gets 'stuck,' that we get periods of the same weather. The same sort of thing happened between January and March/April this year but it was the snow/freezing weather we had instead.
Happy new year! I'm also fed up with mild weather. I want snow. <stamps feet>
What causes the jet stream to be either fast or slow? I live in East Kent and I think it was the jet stream that prevented us having cold enough temperatures for snow for years. That changed in 2010 when the jet stream went all wiggly allowing our part of the country to become cold. Is that right?
Lumpy ~ I'm not sure what causes the jet stream to be fast or slow (need to do more reading up!) but there's a bit about it here. I think you've got it more or less right about it 'wiggling' but (and I only found this out a few weeks ago) it needs to wiggle more south of us, to let in colder air from the north. There are still lots of other weather factors that have to be 'right' for there to be snow but (kind of like when you make a cake) if all the right ingredients are there, you should get snow. But it also affects us in summer as well, as we found out the summer of 2012 when it was a very wet year caused by the jet stream staying south of us.
It's to do with the temperature contrast between north of it and south of it. The greater the contrast the faster the stream goes (generalisation) Canada has had a huge pool of really cold air. Contrast that with further south in the states and you end up with a runaway jet stream.
It is the Gulf Stream which keeps the west warmer than it ought to be. That one is in the sea. The jet stream is high high up in the air and you can think of it like a stream of air with eddies in it (which become low pressures)
Metoffice are saying this about the next few weeks:
UK Outlook for Wednesday 8 Jan 2014 to Friday 17 Jan 2014:
The unsettled theme looks set to continue through the rest of next week onwards into the following week. Whilst this means showers and longer spells of rain will continue to affect the UK, conditions are not expected to be as stormy as of late. The most frequent and most persistent rain is then likely to be to the west and northwest where there is also a risk of occasional gales in exposed areas. Maximum temperatures are expected to often be near or just above average to the south and a little colder to the north at first. Later in the period we may see a slightly higher occurrence of colder interludes between spells of rain leading to an increased risk of frost and icy patches compared to recent weeks.

Whilst current indications point towards unsettled conditions persisting through much of the rest of January, conditions are not expected to be as stormy as during recent weeks. Some signals are also emerging for an increasing risk that the weather may undergo a change to colder weather types later this month. This would also increase the potential for more settled conditions leaving a lower risk of wet and windy spells than has recently been the case.
