There may already be a thread for this so lock this if that's the case.... Met Office weather warnings have been issued for much of the country for heavy, frequent snow showers from tomorrow morning. Warning map: Here is the latest output from the models: 850hpa Temps: Precipitation Type: Very interesting spell of weather coming up very soon, lets all keep everyone informed of what's happening across the country.

This day 201 years ago saw "deep snow brought by an easterly wind" according to Luke Howard's diary. The winter of 1813-14 had started mild but suddenly turned cold on Boxing Day and was just starting to tighten its grip. It brought the last Thames Frost Fair and statistically looks very similar to the winter of 1962-63. You wonder if we'll ever see another winter like it. A similar scenario looks a long way off looking at the models this morning. I wrote a blog on the winter of 1813-14 last year http://wansteadmeteo.wordpress.com/2014/01/06/200-years-ago-the-last-thames-frost-fair/

Here is a selection of wild weather photos that I have collected from the web. The thread gallery here contains almost 70 incredible photos. Apart from an amazing gallery of photos the question is are these severe weather events around the world becoming more extreme, not only this but are they becoming more frequent? (Have placed each image onto a same size background to enable easy viewing without size changing) Gallery: === === === === === ------

With not only winter tyres but Canadian snow tyres fitted to the 4x4, out in the high peak area of Derbyshire, I was prepared for as much snow as could be thrown at me. Well not me personally. With very little in the way of snow this year am I out of the woods yet in terms of snowfall? If I get through the rest of this month it may be time to put normal tyres back on. Anyone got any thoughts? Steve. Buxton. UK. https://forum.netweather.tv/gallery/image/19605-march-snow-13/

okay so here it is a dedicated thread to the SE & EA regional snow depth cup for winter 2013/14 Given the number of people involved in this now it makes sense not to clog up the regional thread with snow depth posts as weather warnings and other information could be lost during busy times - I will leave Tom and Chris to tell you the rules for measuring your snow when it arrives, the deadline has been extended until the end of November so if you haven't entered already and wish to do so please make it known to Tom you want to be included if you are not already on this list....

Since there may be a Cold Winter will there be any cold,snowfall this winter since cornwall doesn't get a load of snowfall.

It's that time of year already - just 50 days until Christmas Day and that can only mean we unleash the new, improved Santa Shaker on an unsuspecting World. Go on give him a shake while you read the Christmas forecast updates, and see what the snow risk is for your region on the 25th. http://www.netweather.tv/xmas

Looks as though there could be snowfall today as cold air blasts south through daytime getting to the far south during the evening time, the wind storm affected many areas yesterday and is still affecting the parts of the north now is dragging down a cold pool as it moves away later, this brings with it the threat of snowfall, and for some, there is likely to be accumulations of snow. Looking through the data it looks as though Scotland most at risk of heavy snow with large accumulations over the high ground and snow settling to low levels at times too. Trough features/shower bands moving through and with low pressure staying quite deep to our far north along with the much colder air then this bringing sleet/snow showers across many areas at some point over the next 24hrs (possibly hail showers too) Some prolonged snowfall over the west and north of Scotland with significant disruption from the snow. Other quite strong snow signals are for northern Ireland, south Wales, northwest England, the Midlands also has some snow signal on the charts for example. But also other areas to as I mentioned above many areas at risk. Risk of snowfall over central Scotland and possibly some getting further east. The south is at risk from high hill snow as showers sweep in here especially during the evening and possibly to low level as much colder air moves in. Here is the GFS 18z Thickness 500/1000hpa at 1800hrs: This shows the cold plunge well as it moves southeastwards. So to finish of this post the snow starts in the northwest today this risk extending south with the cold air by the evening. I must emphasize this is looking like a big snow event for parts of Scotland. ESS

Hello Guys and Good afternoon to you all There Will be a change next week.Making things nicely cold and Some snow (MAYBE) Lets begin the Discussion Right here and right now. Enjoy Ladies and Gentlemen....

Looks like there will be SNOW ICE AND COLD! Hope they enjoy it. Edit:Might want to watch this too.http://www.youtube.com/watch?v=UNPeCZE_dWU

Hi guys, Following the discussion on here regarding the links between UK winters and the Eurasian snow buildup in autumn, I've decided to open a comparison topic. Specifically, we'll be comparing this years run up to winter with some of the previous autumn/winter data. As the weeks progress, I will add to this thread. Please contribute anything if you feel I've missed anything. Solar Situation More data plots available here. http://sidc.oma.be/sunspot-index-graphics/sidc_graphics.php 2010 Snow & Ice 2011 Snow & Ice 2012 Snow & Ice 2013 Snow & Ice October 4th October 4th October 4th October 3rd Ice: 5,696,935 KM2 Ice: 5,045,982 KM2 Ice: 3,927,099 KM2 Ice: 5,675,521 KM2 October 27th October 27th October 27th Ice: 7,751,957 KM2 Ice: 7,688,250 KM2 Ice: 7,169,323 KM2 November 20th November 10th November 13th Ice: 9,575,789 KM2 Ice: 8,861,284 KM2 Ice: 8,714,262 KM2 November 26th November 26th November 26th Ice: 9,920,062 KM2 Ice: 10,163,067 KM2 Ice: 10,050,317 KM2 December 1st December 1st December 1st Ice: 10,281,787 KM2 Ice: 10,505,579 KM2 Ice: 10,487,669 KM2 Arctic Oscillation Links: http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm http://www.natice.noaa.gov/ims/ http://www.nc-climate.ncsu.edu/climate/patterns/NAO.html http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/month_ao_index.shtml Personal Thought. Looking at the IMS images, its apparent that although October 10 started off with a higher Ice Extent value, both 2011, and 2012 saw 1st December kick off ahead of 2010. Taking into account what happened in 2010, If I remember correctly, there was a SSW event 6 weeks prior to the widespread snow event. (Chiono could perhaps confirm this) and if I recall correctly, a SSW can weaken the polar vortex which could go some way to explaining why the Ice extent slowed its advance compared with both 2011 and 2012. The AO index also shows a very negative index value for the winter of 2010/11. 500mb Height Anomalies During a Negative AO So if i'm correct about there being a SSW in 2010, then coupled with a severely negative AO, then the conditions were just perfect for the snow and cold event which ensued. Throw in a spotless sun and you could say it was the 'perfect storm'.

A fresh topic for us to discuss, report and forecast our local weather for Spring 2013.

I thought now was a good time to start the usual winter Alps thread. A couple of blogs from last winter and The ones towards the start of the season contain more about synoptic pressures, but I moved away from that towards the end of the season which would would you prefer. I never get that much feedback, so I asking for that now. Link to last years thread. http://forum.netweat...l__ alps__st__0 As usual comments are very much welcomed and if there are any resorts you are going to please include them here as we can concentrate around those times to those resorts.. Also do we want to use this as the thread to discuss the the Scottish Mountain position or should would that be best kept separate.

So we started the winter cold, then a few weeks of very mild, and about 10 days of snow, but not that cold because of persistent cold cover. We've got 6 weeks left to make or break the winter. A return to zonal rain that plagued us during the latter part of Dec and into Jan and it will be remembered less fondly by the NW members. But it has time yet to be memorable. From a Midlands perspective, it is already an above average winter for snow. But how do you think the rest of the winter will pan out? Here's my punt. Wind, rain and floods into early Feb, followed by a northerly and more snow. Then very mild for early March!

Another 2006? This March sure feels like it at the moment, bitterly cold with snow fall as you can see. http://youtu.be/wmLBR2UY0uE But 2006 was the last of the good, "hot" summers in recent years so I am hoping this is a good omen as it turned out to be then. Fingers crossed.

Has anybody ever experienced this weather Phenomena at all.? I know I haven't had the pleasure, maybe one day eh! Thundersnow, also known as a winter thunderstorm or a thunder snowstorm, is a relatively rare kind of thunderstorm with snow falling as the primary precipitation instead of rain. It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from any other type of thunderstorms but the top of the cumulonimbus are usually quite low. http://en.wikipedia.org/wiki/Thundersnow Typically, a thundersnow event occurs with the majority meteorological recipe coming from a thunderstorm forming over a body of water. When the colder air from a normal winter front collides with the warmer air over the water--you're likely to get heavy snow and thunder clapping concurrently. But it isn't just that cut and dry and harmless. All the variations involved in thundersnow make it frequently dangerous if you're caught out outdoors when it happens. Some of the examples of what thundersnow can do based on recorded bizarre weather events in history: When thundersnow happened, strangely, in New Mexico once during the late 90's--a ski lift at a ski resort was hit by lightning and heavily damaged. In one of the interesting variations--snow fell as ice pellets. These ice pellets are frequently are larger than typical hail...hence causing more injury if you happen to be outdoors with no undercover areas within sight. Buffalo, NY (during one of their massive snowstorms in 2006) reported a heavy thundersnow event that went on for hours. It's said that it's one of the longest reported thundersnow events in weather-recording history. People reported heavy snow falling with heavy claps of thunder and lightning strikes all through the night and day. This seems to give the indication that thundersnow can turn into a circular and prolonged storm if the conditions are just right. Please discuss:

Please carry on here. Please be polite and try and justify your posts with reasoned analysis and charts where appropriate. No bickering, trolling or anything off topic. We are seeing a lot of postings with musings from twitter - please only post these if they are relevent to the models and are taken in context. Please quote the source and give a link - otherwise your post may disappear as this is not the rumour model thread. Thank you.

New thread for the Ireland regionals. Ramp away, discuss the ever changing Ireland weather and snow prospects. Be good, no arguing or I'll be chopping heads. Getting colder as the day is coming to an end here, fingers were getting numb under the gloves.
