  1. The severe winter of 1978-79

    This was 7 years before I was born, however my Dad often talks about how cold this winter was. He has a memory of heavy snow starting at the New Year and snow still being on the ground in March without a complete thaw - even in London. Not sure if that's entirely accurate or just a perception he had because it was cold/snowy so often that winter!
  2. Well it’s quite obvious if you have one of the highest mountain ranges in the world (the Alps) you’re going to get snow. I didn’t say it has “nothing” to do with altitude. I said altitude is not the main reason we don’t get much snow. There are are plenty of places around the world at our latitude or even further south that get a lot more snow than us. The reason is the UK has a temperate, maritime climate. We are an island surround by water warmed by the Gulf Stream. We do not have a continental climate. Hence cold air is significantly modified before it reaches our shores.
  3. Not really. For our latitude we get very little snowfall. The makn reason is not altitude - as someone else pointed out, New York gets much more snowfall than us and is at sea level. New York is also on the western edge of a huge, relatively warm ocean. The UK is an island, our waters are warmed by the Gulf Stream, our prevailing wind is from the SW/W, and even when we get cold air from the NW/N/NE &E it is heavily modified compared to other areas of the globe at our latitude because it passes over relatively warm water. Its stating the obvious here, but places like Moscow, New York, Toronto, many parts of central and Eastern Europe etc are directly connected to the Artic by a continental landmass. The most “continental” part of the UK climatalogically is generally the SE due to its proximity and short sea track to Europe, and distance from the Atlantic. Therefore we will always struggle to get deep cold in the UK, particularly down south. So many things need to fall into place!
  4. Quoting my own post, here is the BBC weather forecast from 4th Feb 2012. Heavy snow for central, southern and eastern areas. Turned to rain in the west, had all snow down here in London from this with several inches: Proves the old saying of get the cold in first etc...
  5. We may not have got those uppers in Feb 2012, but there was a great cold spell with significant snowfall for the SE & E of England on about the 4th from an advancing front from the west pushing up against a cold block.
  6. Classic in the sense that all the ingredients were there for significant convection, and it’s delivered. It gave the most snow to this part of the world (London) since Feb 91.
  7. I would class Feb 2009 as a classic convective easterly. It just didn’t last that long.
  8. It’s only been 12 hours since that 168 chart was produced, so I think you’re wrong here. Will need to see tomorrow mornings 144 chart to compare.
  9. As mentioned in one of my replies above, cold uppers are needed in order to generate snow showers off the North Sea. Deep cold uppers are not needed in battleground scenarios where weather fronts push up against a block of surface cold. For example both snow events from December occurred with relatively mild uppers.
  10. Useful for a snow event where frontal systems push up against the surface cold. No use for generating convective snow showers off the North Sea.
  11. True, however if we want showers of snow from an easterly, the uppers matter more than they do in a battleground scenario.
  12. Cold rain and sleet here in Chingford unfortunately. It snowed earlier this morning but nothing settled
  13. A lot of people on the Midlands thread are reporting very little settling snow.
  14. Not expecting much more than a few wet flakes in the wind
  15. Even for areas further north and west I can’t see this being much more than a transient snow event with little settling at low levels, compared to the last snow event earlier in the month. Higher ground the exception obviously
