That's enough for me. Agreement and consistency enough to give an 80%
chance of this forecast achieving outcome. **At T240 on 16/05, the UK weather will be dominated by a slow-moving low pressure system. Unsettled weather will predominate and the "drought" will have been well broken in many areas. Indeed, some areas will be hoping for some drier weather by then. Temperatures will probably be close to average, but that will depend on the exact location of the low. It could turn cooler, with a risk of late frosts in the NE if the low is centred over the North Sea and skies clear for any time at night, but daytine temperatures will rise quickly in any sunshine.** The situation is still blocked, but I see our recent, anticyclonic pattern shifting eastwards, to leave the UK under much cloudier skies, with a jet to the south of the UK. No great warmth at 10 days. |

No great warmth at 10 days. That figures. I'm going on holiday to north Wales from the 15th to the 21st. I knew that, climatologically, that was a good time of the year to go, but I'm now starting to regret my choice of dates. ![]() -- John Hall "The covers of this book are too far apart."

Just ask my 10 + 12 year old, I'm sure (I hope :-o) that they'll agree!! Cheers Neil |

slogging up mountains. I'll be going up Snowdon as part of it, but via the railway. -- Great either way John, loved the walks up and down Snowdon but equally enjoyed the railway trips. Hope the unsettled spell isn't going to continue all through May, we normally go to Cornwall first week of May but this year we opted for 21st thinking it would be warmer. This last week would have been perfect but not so sure about the last week of May now ![]() Graham |

And today's Met Office 6-15 day forecast seems to have followed his lead. ![]() -- John Hall "The covers of this book are too far apart." Ambrose Bierce (1842-1914) |

Cooler conditions now prevail, there is unsettled weather for many, the main jet is to the south of the UK and the drought has been broken for many. It's the "slow moving" low pressure system which invalidates the forecast. I was expecting more blocking in the Atlantic, producing the slow moving low pressure over the UK, but there is actually more mobility than the models were showing and that I had anticipated from 10 days out, though the effects of that mobility are being felt further north. This is a break in the blocked pattern and the FAX charts for today and the next few days confirm that. http://euro.wx.propilots.net/ Incorrect 84/105 = 80% |

For a start, low pressure is no more dominant than high pressure. If you take England and Wales this morning, pressure is above 1016mb, and isobars show anticyclonic curvature. Also, the main jet (Polar Front Jet) is not to the south of the UK, its up near 60N and is steering the lows just to the north of Scotland. If you are looking at a jet to the south of the UK its the subtropical jet and that is always to the south of us. I would also question whether the drought really has been broken for many. Total rainfall here over the last 8 days amounts to just 0.1mm, and I am sure there are many other parts of England, at least, with still well below average rainfall.
