Indeed, I have to say I would not like to be a MetO forecaster today. There is a risk of heavy snow in the SE over the next few days and also a risk of absolutely nothing as well. At the moment it seems they are siding with the absolutely nothing route and it appears that they are already wrong!!!! -- sitting on the Olympic Park at the moment and it's snizzling!!

When do you think our best chance for snowfall is? I'm thinking Wednesday night into Thurs morning with the cold uppers coming in, it may create some good convection in the North Sea with the vast temperature differences and set us up with a Kent Streamer (winds are to N/E'ly to be a Thames Streamer). There is still time for change................................... Thoughts anyone?

Yes but this chart is also showing it should be snowing now. http://cdn.nwstatic.co.uk/gfsimages/gfs.20120131/06/06/prectypeuktopo.png The GFS snow chart (as I'm sure you know) is pretty vague at best. To be honest I think our chances of substantial snow fall seem to be diminishing with every run at the moment Such a shame as the charts a few days ago showed us being in a real freezer akin to last winter. Still we should have a good chance of a streamer or snow showers at some point between wed night to friday. However I think Roger's prediction of thundersnow and 60cm will be far of the mark............................Yamkin, please prove me wrong and say we'll all be getting 6ft drifts

Latest 12z run looks like a downgrade compared to the 06z in the early stages. HP is further to the east meaning the cold uppers take that little bit longer to reach us and I'm guessing that upstream we will see them leave sooner IF the Atlantic pushes in. Incredible the amount of difference 100 miles makes.

The GFS precip charts are rubbish for use in detail, good for looking for trends. Use the NAE precip chart. It's much better.

Met check is saying Max of -1c from Thursday through to Sunday...........with a bit of snow in there as well. http://www.metcheck.com/V40/UK/FREE/dayforecast.asp?zipcode=gu4&day=3

I live near Guildford (south and west of london) and we benefited alot from Streamers last year and the year before. In Feb 09 we got 16 inches in one night and around 10 inches last winter over a 3/4 day period. Hopefully the streamer that COULD happen later this week will give us the same amounts .

At present yes. The models are showing the worst winds to be in northern france........mostly, so this will include Paris. I would'nt want to go on any large rollercoasters if I were you. Of course the models can and most probably will change, I'm expecting the LP to shift further north, perhaps 100 miles. So this should aleviate Paris a bit. Not looking great tho. Hope this helps.

That would indeed be unpleasant. Planning on climbing Aconcagua next year. I checked the weather there a couple of months ago. Wind chill was -65c. Now that is cold.

http://cairngormweather.eps.hw.ac.uk/current.htm -1c and windspeed's of 165mph. Wonder what the windchill is? haha

Highest gust now 151 mph at Cairngorm Summit. Metoffice ^^^

130mph near Fort William. According to the BBC.

This quoted from the BBC website. A gust of 89mph has been recorded in Tiree. The Ski area at Aonach Mor, just outside Fort William in the Highlands has reported a wind gust of 130 mph. That's pretty insane. I'm glad I'm sitting down in london in a nice cushty office at the moment! Good luck.

Can't believe no one has mentioned the storm out near the southern tip of Greenland. http://hw.nwstatic.co.uk/gfsimages/gfs.20111207/06/63/airpressure.png That is one hell of a low pressure......more powerful than the one hitting Scotland over Thursday night.

http://www.meteociel...map=0&archive=0 That's quite a nice little change . Would be pretty chilly up north. I know this is way out in FI but it's a great chart!! http://www.meteociel.fr/modeles/gefs_cartes.php?code=0&ech=384&mode=0&runpara=0

How long has this HP been sitting over Greenland for now? It seems it has been there for months. Is this normal for summer?

Never? Isn't that why we love Yamkin. It will be mid summer and he'll be screaming about thundersnow!!!!

Has anyone seen the 12z GFS? http://www.netweather.tv/gfsimages2/gfs.20110302/06/93/h850t850eu.png Surely if this high moves north or west we'll be right on the money? If it moves north we get a bitter easterly and if it moves west we get clobbered by a cold northerly? Both would bring back cold temps. Anyone care to comment?

http://www.meteociel.fr/modeles/gefs_cartes.php?code=0&ech=180&mode=1&runpara=0 That would be nice and cold.
