    Shift north on 06z GFS illustrated image.thumb.png.f951f3f5abebd9fc88bcd83fa32faa31.pngon this chart. Not resolved yet!

    Yes, there is still some discrepancy between the models even at this range. The peak wind gust for Brighton varies between 55 to 87mph across the most recent models, thats quite a wide range.

    Ground temps are widely 5-7c across the south and 3-5c in the north. Any snow that does fall will very quickly melt. A complete waste of time. 

     

    I totally agree. Soil temp down on the Sussex coast around 11c at the moment with the recent warm and dry weather. Not expecting anything to settle apart from perhaps on the very tops of the Downs.

    Possibly an even stronger storm on the 12z UKMO - large swathe of 80-85mph+ gusts inland. Will be interesting to see how the evolution differs to the GFS which seems have tempered the strongest gusts.

     

    Tend to agree, UKMO 12z stronger for the south east. A few frames later on from your chart shows Brighton at 90mph peak gust.

    I vaguely remember that issuing an Amber kicked off processes with Councils and emergency response teams. I'm not sure the Amber is of much use to the public compared to a yellow. Both are about severe weather, but what is the difference? It just confuses, or lessens the perception of Yellow.  In the last storm, it ticked all of the amber criteria about damage and power/transport interruptions, no amber. It isn't clear       A red - fair dos, don't go out. 

    Correct. Amber and Red trigger certain processes with councils, blue light services, power companies, transport and other national infrastructure organisations and operators. Such things like cancelling leave, bringing people in on days off, moving equipment around or safeguarding sites etc. So such decisions are not taken lightly as there is a cost implication for these services when they do. For example, one of my previous employers would block book hotel rooms near to the workplace in case staff were unable to get home, in the event of certain warnings from the Met Office.

    i just dont get how brighton gets 1cm in 15 minutes yet 10 miles away theres no snow, even though the radar says snow??

    As someone who knows a thing or two about radar, the beams generally look "up" or at least on the horizontal, not down at the ground. So they only see what is falling in the air, and not what is actually hitting the ground. I regularly see people on these forums wondering why a blob is over them on the radar but they're not seeing anything at ground level - this is why.

    We're now in the period where getting excited over where a line on a map may be drawn is largely irrelevant. Models shows the general area, not an exact it will/wont snow here depiction. Same with thunderstorms, a general area is given but some places will miss out entirely. The closer you are to the edge of a "line", the more you should expect to be disappointed if snow is what you want!

    Storm Doris - Atlantic Storm 4

    How i'd love to be a fly-on-the-wall at NATS tomorrow morning, i'm hoping that airlines are already placing contingency plans in-preparation for Doris with Liverpool, Manchester, LBA, Midlands, Doncaster/Sheffield all expected to bear the brunt of the strongest winds tomorrow morning throughout the rush hour. Not to forget the +50mph gusts around the other areas of England and Wales, on top of the likely rail and road delays.

    Message to operators is to fuel accordingly and be prepared for extended holding. Diversion capability limited tomorrow so main diversion options for London limited to near continent, although Amsterdam expected to have strong winds too.

    Birmingham most likely to be the worst affected simply due to the crosswind component. Leeds will probably struggle too with its runway orientation.
