  1. So where do we go after this week is sorted which may well take a couple of days to sort out the fine detail? Well the 5-10 anomalies are in pretty fair agreement, With the cold trough over the eastern N. America, HP pushing up in mid Atlantic and the negatively tilted trough Iceland down through the UK into Europe with the upper flow veering NW. Ergo the depressions bringing unsettled weather have a tendency to swan SE thus bringing the colder air further south and perhaps increasing the chances of snow at lower levels although the chances of this remain quite slim with the air in general not really in the cold zone. In the ext period there is a divergence of opinion. The ecm and NOAA are on the same page with less amplification upstream, less influence from the Atlantic HP and  the trough still the major player over the UK with the wind backing to nearer westerly. Still unsettled but perhaps less wintry. The GEFS on the other hand still rends towards some amplification upstream and weakens the UK trough and although the flow is still zonal westerly the HP is perhaps more influential than the other two
  2. Article Researchers from the international Past Global Changes (PAGES) project write in the journal Nature Geoscience that they have identified an unprecedented, long-lasting cooling in the northern hemisphere 1500 years ago. The drop in temperature immediately followed three large volcanic eruptions in quick succession in the years 536, 540 and 547 AD (also known as the Common Era CE). Volcanoes can cause climate cooling by ejecting large volumes of small particles - sulfate aerosols - that enter the atmosphere blocking sunlight. Within five years of the onset of the "Late Antique Little Ice Age", as the researchers have dubbed it, the Justinian plague pandemic swept through the Mediterranean between 541 and 543 AD, striking Constantinople and killing millions of people in the following centuries. The authors suggest these events may have contributed to the decline of the eastern Roman Empire. Lead author, dendroclimatologist Ulf Büntgen from the Swiss Federal Research Institute said, "This was the most dramatic cooling in the Northern Hemisphere in the past 2000 years." Read more at:
  3. Oh a tricky business.................running a little further north. Handy position for the jet. More runs required. And then
  4. Latest from the woodshed UK Outlook for Saturday 13 Feb 2016 to Monday 22 Feb 2016: Unsettled and rather cold conditions are likely to continue through the weekend. Cold, showery conditions across the north at first may give spells of snow, with overnight frosts likely. Further south more prolonged spells of rain are likely, with a risk of this turning wintry, most likely over high ground. It will be windy at times, with a possibility of gales, most likely in the northeast and far southwest. It may turn drier from the west early in the following week, although remaining cold with overnight frosts. Later on, unsettled conditions are likely to return, with northwestern areas seeing the wettest, windiest weather, and southeastern areas likely to see more in the way of dry weather. Temperatures returning to near normal, although with overnight frosts still possible. Updated at: 1312 on Mon 8 Feb 2016
  5. Latest from the METO Regional forecast for South West England Windy with scattered showers continuing. This Evening and Tonight: The strongest winds will gradually ease, although it will remain windy with local coastal gales. Scattered showers will continue through the night, these perhaps wintry over the moors. Minimum Temperature 5°C. Tuesday: A cold and windy day with further local gales likely. A mixture of scattered heavy showers, wintry on hills, and sunny spells with the showers becoming less frequent later. Maximum Temperature 9°C. Outlook for Wednesday to Friday: Cold with easing winds on Wednesday and Thursday. Some scattered showers, wintry over hills although dry for much of the time. Strengthening winds with further rain on Friday. Updated at: 1319 on Mon 8 Feb 2016
