Looks like we're in for a battering during another stormy night in
France - on the face of it, probably worse than Thursday night. We have orange vigilance warnings for much of the country - expecting the worst around 02:00 Sunday morning. CK |

Simon S (South Yorkshire) ================== Latest sat pics indicate west-east elongation well underway with T-bone cold front weakening. Even patch of drier air behind cold front now as cold air conveyor descends behind the deepening centre. Seclusion process well underway with cirrostratus now invading the sky rapidly here in Devon. The low may well end up more elongated than expected earlier but main centre with strongest winds still looks in line for passing somewhere near Channel Islands and then quickly NE to Dover Straits. Heavy rain might end up further north and west. Cold air tuck behind it will turn the precip. wintry on its western edge with a spell of wet snow possible over high ground. Will -- |

Keep up the commentary Will, I'm sure a lot, like me, are learning from it. Driving rain and E to NE gales will prove a test for my recent paintwork and rendering- which I think will be OK, but I'm not sure how my occasionally leaky roof will cope. Fingers crossed! |

Will -- Cirrostratus has thinned again here. Now virtually calm in pleasant sunshine, the thin veil of cirrostratus having helped to damp down any Cu development. http://www.minack.com/min02_7ref30.htm Currently around 10C, but feeling warmer due to the lack of wind. Dewpoint 7C Certainly doesn't look good for the Channel Isles around the time of tomorrow mornings high tide. Forecast mean speeds for the north Cornwall coast tomorrow morning have been downgraded slightly I'm pleased to say - still a Force 7 peaking at high tide though. South coast (of Cornwall) will be offshore - so no problems here in Mount's Bay. Force 6 ESE onshore forecast for Penzance Tuesday, on the biggest tide of the year, but fortunately the pressure will be a good deal higher then, and certainly no big swell. Graham Penzance |

Fingers crossed! =============== 1600 imagery shows a very elongated system now. In my experience KS cyclones sometimes slow down at this stage. Centre is in Biscay ATM with a curl of strong winds about to slam into Brittany. The T of the T-bone is way ahead east almost into Normandy now. It looks on track as far as I can tell but I still fancy the rain to be extending further west and possibly quicker into the SE due to the elongation. My only concern is that the SW side of the low seems to be slowing which may be a sign that the gradient is tightening more, hurricane force? We should be safe in Britain but northern France is right in the firing line for some massive gusts. Will -- |

Simon S (South Yorkshire) Not sure about that, but the 12Z GFS seems to be moving the Low through quicker than on previous runs. It's now forecast at 06Z tomorrow to be at roughly where it was previously expected to be at 12Z, and at 12Z it's at about where it was previously expected to be at 18Z. -- John Hall "Acting is merely the art of keeping a large group of people from coughing."

CK Getting the same kind of thoughts here in Folkestone... Would I be correct in thinking the track if forecast to be a little further north than was expected? Simon S (South Yorkshire) The gfs has changed the track over the previous week, certainly. On Wednesday, when Richard opened this thread: http://groups.google.com/group/uk.sc...b454a2f5d8d5e# the track then was, if anything, a little further to the NW and as a result, Will was including Wales in a snow firing line. 24 hours later, a couple of us mentioned that the low was showing signs of assuming a track more to the SE of that original projection, especially on the gfs, with the major fallout being over N. France. That probably will still be true, but now, 2 days after that, the track is being modelled a little further to the NE again. So you are right Simon, if you choose Thursday's output as a datum; if you choose Wednesday's path as a starting point, it is actually a little to the SE of what was being modelled then. I think the models, so far, have done very well with this, but a final judgement on this could only be made after tomorrow. We should just about stay dry in Exeter this evening, but I'm expecting to be awakened by rain and winds in the night. (I'm also rather hoping Giraffe will be free from a terrorist assembling a bomb in the gents!) |
