Frost Watch Autumn 2012

coldest night for date since 1975! for Inverness and colder than that by 2 deg F http://weather.glads...rmation〈=en -
Friday to Sunday Snow Cover Thinking that South Norway will keep a positive amount of snow this week and the more northerly negatives may go. Fresh snow in Kiruna Sweden. The area west of the Siberian high pressure will be our chance to see for the snow move farther west by next weekend. http://www.weather-f...=none&type=prec Snow risk for Scotland decreased from what it was and ten days to more snow chances....subject to change!

Chart seems to show a slow down in Siberian snowfall and an increase in high pressure leading to cold. So less snowfall with more cold for now and then some more snow, some of it farther to the west than before in the 3 to 5 day range. http://www.wunderground.com/cgi-bin/findweather/getForecast?query=zmw:00000.1.20891 shows -22C by Thursday!

Winter 2012 / 2013 Part 3
LincolnSnowstorm replied to Jane Louise's topic in Spring Weather Discussion
The teachers link was long so here is the short important bit below , just brings things things to life when people are active getting ready for winter. We just missed out last year on some very harsh weather that was killing many homeless people less than 800 miles to our east , will we be as lucky this year? Decent snow and cold is fun and very welcome but a few weeks of record lows say -20C in England and lower in Scotland would be a big test of many peoples ability to keep warm , and cause headaches with plumbing,cars and lorries so thanks for the replies so far just wonder what this winter has a one in ten chance of doing because of the blocking,ice melt etc rather than what is likey or the out come of a one in a hundred probability. It could easily go the other way like you say 'that doesn't necessarily mean that we will experience cold conditions, the "kink" in the jet-stream could easily form in an area which would leave us in a mild airflow' Heres what the teacher said. Twice a year I give my seasonal meteorological predictions to the school, and mid October is the time for my winter forecast. 2012-13 is likely to be a colder than average winter characterised by disrupted westerly airflows, and weeks when blocking anticyclones bring very cold air in from the North and East. We can expect a number of periods of extreme frost and some significant snow falls. The reason for the colder than average winter weather is the location of the jet stream. In recent months, the jet stream has tended to sink further south than usual. For much of the summer instead of sitting over Northern Scotland, the jet stream ran across England and Wales and was tracked by low pressure systems which gave us the second wettest summer on record. If the jet stream maintains its southerly trajectory this winter then instead of sitting over England as usual, it could meander south to France. This would expose the UK to much colder polar maritime air. There could be significant snow before Christmas, and as such The Perse has already begun its bad winter weather planning. The UK has a poor record at coping with cold weather, and too much of our infrastructure closes down too quickly in the event of modest snowfalls. The Perse is stockpiling salt and shovels, and aims to be open whenever possible. In bad weather parents must decide whether it is safe to send their children to school, but schools should do everything reasonably possible to stay open. Once schools close parents have to stay at home to look after children, and an economy already struggling with snow induced transport disruption grinds to a halt. We may be entering a period of colder winters, and if so we will all have to become better at coping with the white stuff. -

Interesting forecast of a colder winter http://www.cambridge-news.co.uk/Educati ... 102012.htm Talks about the jet stream being very low , If we have an extreme case of blocking anticyclones does that put us in uncharted territory compared to other cold winters? And if so what is the potential or outcome overall for the winter, would it easy to be colder than previous daily ,weekly and monthly temperature records -

A week like the last week in November 2010 would be cool -
and even choose which days to show or hide so here the link again http://www.natice.no...a-1mo-loop.html (to be repeated reguarly so new members and new guests donot miss out) see post #422 as to why its not cool to just post a before and after attachments. Snow has come to Southern Norway negative to positive amount in one day! Make animation link http://www.myspacege...n=animatedimage

The Euroasia snow cover has doubled in a few days so to some keen observers that would count as a massive increase and I would agree but like you say it's early days and so I'm waiting for the really big increase that may happen as the sun sets on the northern hemisphere. About the animation v pics If someone describes something on a map you refer back to it without straining your eyes looking at up to 31 days at a time , good once or twice but not relaxing to look at all the time, maybe it's just my preference.
