That was your Siberian express to the east of that long southern plunging jet stream. If it decides to move west you're ice cubes.

Both metcheck and weather forecast uk have expressed the weather models are giving confidence to a cold pattern in 7 days.... I found a synoptic chart the other day of the prevailing system that produced the '47 January and on, winter snow....eerily it looked like the charts from last week but with low pressure further south. Here it is en.m.wikipedia.org/wiki/File:Metoffice_3_feb_47.jpgThe common theme here is, the previous cold winters ('08-'13 or there abouts) from my memory were caused by blocking high pressure systems, the snow came as weather fronts from low pressure being held away from the UK, encroached on the colder airmass. The existing and the '47 time frames are dominated by low pressure, which when positioned correctly appear to draw cold air into the moist depression. This would explain the intense '47 snowfall??

Both metcheck and weather forecast uk have expressed the weather models are giving confidence to a cold pattern in 7 days.... I found a synoptic chart the other day of the prevailing system that produced the '46 January and on, winter snow....eerily it looked like the charts from last week but with low pressure further south. Here it is en.m.wikipedia.org/wiki/File:Metoffice_3_feb_47.jpgThis is in 2 days... www.metcheck.com/UK/synoptic.aspApologies for links....still waiting for broadband :-| From The History of British Winters They don't give 1900-01 much play ... but it seems pretty bad with 5-7 feet of snow. Of course, you probably don't have a chart for that year. 46-47 was at the peak of an AMO peak SC18, no El Nino, while 1900 was at that 'drop off point' with strong El Nino. Don't look down. From 1895-99 the UK had 4 consecutive years of little/average snowfall, of which the only noteworthy fall was of 1ft in the Eastern spine of the country. 1899-00 saw general snow of 1ft, 2ft in places. The following year wasn't exceptional either, although 5-7ft of snow was recorded in North Wales and Northern England. Both years were snowy. 1946-47: The year you've most probably been waiting for! One of the snowiest winters to date, probably the worst since 1814 (see part 5). Snow fell on the 19th December in Southern England. Then there was a notable mild spell, extremely mild in parts, with 14c being reached by day. Then from the 22nd January, it began! There was continuous snow cover from this date, right up till 17th March! Late January saw 7 inches of snow in South West England and the Scilly Isles (unusual). Early February saw the turn of the Midlands (Southern) and East Anglia, while Northern England, North Wales and Eastern Scotland saw snow in late February. In early March there was a blizzard in England and Wales, with 1ft widely, and 5ft accumulated on the hills! 12th March saw snow for the Border Country. 1946-47 was strange, because it started up late, and lasted a long time. I think 2003-04 will mirror 1947 in lots of ways, mainly in terms of snowfall, but not so extreme and long lasting. Very snowy.

Looks like we will have -23C tonight and then warming to -4 by Sunday. I just went out to get some beers on foot with ski trousers thermal underwear and a thin head thing to go over most of my face plus hat with jacket and hood. A bit cold around my face after I got back from the 400m round trip. Further North from here I have been cycling before with similar clothing in -26C but I had a full head protection with metal breathing gauze. Some people here seem to have trouble breathing in this kind of cold but after than it being cold I don't really notice it breathing wise.

We will be getting that this weekend Andrew. Not bad tho, as -20F is sorta normal. It is -30F that one takes notice, and anything after -30F doesn't seem much different.

The Uk always has news of old people dying during cold weather. When I was a child the upstairs of the house was unheated, the ice formed on the inside of the windows at the bottom with condensation all over the glass - in the mornings mum would light the fire and we would run down and roast in front of the fire and play games of who could sit down without screaming because our clothes were so hot. Central heating has become much more common but people still live without central heating in old draughty houses. Meanwhile in Helsinki we have -25.4C/-13.7F on a thermometer covered by the terrace facing the house and not in sight of the sky. Pretty cold for here with us being so near the Baltic Sea. I saw -24.6C here in about 2010 when we were having a few really brutal winters. The lowest temperature ever recorded in Helsinki was -34.3°C in 1987. A temperature like that is a bit of a numbers game because given the right conditions extreme cold can come from Russia whereas typically Finland is protected by the Gulf streams influence. Finlands lowest ever temperature was in 1999 at about -55C but even if the world warms up we could get lower temperatures when the thermometer record is such a very short one. Similarly we can get higher highs even if the world is getting colder.
