  1. Enjoy BW, too cold by far for me, but look forward to your photos. The Wengen area forecast suggests 20-30 cm for above the village and cold enough in the village from late Saturday for more snow again. Most ski lifts and runs are expected to open for the weekend with a full opening (fingers crossed) the following weekend.
  2. Dry and clear with ground frost, current low at 0.4 C
  3. Yes the 3 anomaly charts suggest a spell of colder weather. Obviously day to day changes as per Fax charts but the overall pattern does look to be setting up for cold weather for a week or so. Beyond that then best to wait and see for a day or two. links below http://www.cpc.noaa.gov/products/predictions/610day/500mb.php http://mp1.met.psu.edu/~fxg1/ECMWF_0z/hgtcomp.html The obvious question that will come, will it snow for ??. These charts do not tell us this, the synoptic charts are for that question, and a need for the main models to be showing very similar charts, upper air profiles, humidity, surface pressure profiles etc. over the same time scales.
  4. Clear skies after slight rain overnight, current low at 5.9 C
  5. Yes re the 500 mb anomalies Nick has posted above. The 3 are more or less showing similar patterns and now have done for a couple of days. GFS is less keen, this morning, on the way shown on the other two. Sufficient agreement I think to suggest the cold outbreak will last at leasr 2-3 days possibly 4-5 days. But not a prolonged spell is how I read it using the anomaly charts. Yes they are mean charts so day to day variations can and will occur but their being 'mean'charts does give a good indication of the overall 500 mb pattern for the days shown. I would be a bit wary of suggesting anything longer, just yet, than what I suggest. Best to take things gently. links as usual below http://mp1.met.psu.edu/~fxg1/ECMWF_0z/hgtcomp.html http://www.cpc.noaa.gov/products/predictions/610day/500mb.php

    Very much under the streamer as you call it. It snowed non stop from 1700 to 0800 with 34 cm falling in that time
  7. Cloudy, dry mild start after rain earlier, so far 1.4 mm, a low of 10.2 C
  8. That's right.The red shows above average pressure up there against climatology but if you follow the isobars(black lines)they show roughly the wind direction.Still plenty of energy flowing south of Greenland. Not surface isobars, the chart is for 500 mb, about 18,000 ft, so they are contour lines. Yes the lines do show the predicted direction of the 500 mb flow. Sorry if I sound a bit pedantic.
  9. This morning ECMWF-GFS both show a meridional flow into the UK, Ridging/+ve heights in the Atlantic up to Greenland with very marked troughing over the UK and then down into Europe. The NOAA version last night did not show this so a sitting on the fence time until all 3 are very similar for a couple of days.
  10. Cloudy and spots of rain after more rain earlier, 1.8 mm so far, low of 5.6 C now on 8.7 C
  11. Is it possible for some of you to actually post in the correct thread please? model discussion NOT bits out of Met forecasts.

    This might interest some of you Snowfall of 30 November into 1 December in this area.doc I have lots of photos and a couple of videos but all are too large to put out here
  13. The anomaly charts are not in real agreement with one another so expect fairly marked changes on the models until that is sorted. Just my view but a changeable period looks the best option at the moment.
  14. Patchy cloud but a lot of blue about, just shy so far of an air frost at 0.1 C, frost on cars and roofs/grass.
