**In 10 days time, on Saturday 23rd January 2016, the UK will be under a zonal weather regime. Our weather will have an Atlantic source and it will be controlled by a large European high pressure system. **
The colder weather of this week and into next won't last long. |

I regularly read the Model Output thread on TWO and the gist I am getting from that is that over the past week or so the models hwve been flip-flopping like mad are hard pushed to call anything at 5 days, let alone 10. -- Col Bolton, Lancashire 160m asl Snow videos: http://www.youtube.com/channel/UC3QvmL4UWBmHFMKWiwYm_gg |

That's certainly not how I read the 12Z operational runs of the ECM and GFS. Though zonality will probably have returned to the north by T+240, in the south it looks as if we'll still be close to the centre of an anticyclone, with what little wind there is from the south or south-east. Though the air will by then be very mild aloft, as shown by the 850mb temperatures, I'd expect there to be a marked inversion, with temperatures near the ground still decidedly chilly. Of course, based on recent model performance it could all change by the next run. In fact based on the recent runs I'm rather surprised that Dawlish's tests for consistency from run to run have been met. -- John Hall "Honest criticism is hard to take, particularly from a relative, a friend, an acquaintance, or a stranger."

But there is no point in giving a running commentary on the inevitable twists & turns prior to the 23rd so I will leave it at that for now ![]() -- Col Bolton, Lancashire 160m asl Snow videos: http://www.youtube.com/channel/UC3QvmL4UWBmHFMKWiwYm_gg |

It looks like it *could* all hinge on what the low (FAX chart L1010 at 120Z) on Monday does. Will it stall, turn left or turn right?

A higher degree of risk than usual. One of the problems being greater day to day fluctuations in the models, a trickier than average synoptic pattern and the UKMO holding a different view much of the time. Of course that one isn't part of your formula as it doesn't go out to T+240. I suspect you will be right but noticed you didn't *forecast* much in December when there was bigger cross model support at that range. Dave |
