    Well bbc have us down for 1c on Friday, so thats from the dogs mouth.

    My advice is that this is a fluid situation and what is forecasted for 5 days time will more than likely change, good or bad nothing we can do about it but wait and see what occurs on the day.

    Thought I'd have a look at what the CFS is suggesting for northern blocking this month.

     

    Here's the chart with the latest blocking data (chart explanation here http://forum.netweather.tv/topic/77743-winter-20132014-forecastshopesdiscussion-thread/page-117#entry2806211)

     

    Posted Image

     

    The average of the last 2 months is 1.5, or between weak and moderate blocking (+ve SLP anomalies to the north). The frequency of the different categories (from -5 to +5) can be seen in the chart below.

     

    Posted Image

     

    Moderate and strong +ve SLP anomalies were the most frequent outcomes projected by the CFS, totalling half of all forecast in the last 2 months

    If we take -5 to -2 as the negative SLP category, -1 to +1 as neutral and +2 to +5 as positive, the percentage of days with those categories forecast are 8.3%, 33.3% and 58.3% respectively.

     

    So going by the CFS, we should expect higher than normal sea level pressure to our north this December.

    I'm pretty much still a newbie in this forum... I used to post a couple of years ago but went back to lurking since then so I guess I'm fairly unexperienced... so from what I can tell it was looking good for a cold spell from the 6th but now we are within a week of it it only looks to be lasting just one day is that right??

    Just popped in MOD and its the same pessimists ruling the roost as per usual, expected a mild zonal fest on the models and was shocked to see a stonking ECM 00Z and GFS 06Z run, really they are both fantastic, what the hell are the doom merchants on about.

    Sorry, what's MOD?

    I must say that one of the things I am most looking forward to now over the next 2 - 3 weeks is to see whether RJS's forecast for December stays rock solid and we do indeed end up in Euro high territory with mild temps around Xmas. My own thoughts for December are already looking a bit ropey because height rises have moved further to the east... and I find it fascinating that Roger is able to pick these things with alternate methods and get it accurate. I wont even care to be honest if the overall CET prediction is miles out - its all about pattern for me.

     

    Not that I want a mild December at all.... quite the opposite: but it will be a fascinating comparison all the same.

    Another cold March? CFS teasing again, we can live in hope! Though would want cold and snowy weather Dec-Feb.

    Notice the artic high, a massive part in trying to get colder weather here and usually helps us out!

    Looks like December 2013 is panning out to be a mild one, though not exceptionally mild in my opinion.Sadly, this week's cold snap will be all too brief. Don't think it will even reach this part of the UK to any great extent.The old problem of a toppling high unfortunately.Mind you, I hate driving in it so I suppose I shouldn't complain.

    Not sure where you got the 2C max from, from the GFS?post-18937-0-90509600-1386057349_thumb.jAnd remember, it's not all about the upper temperatures! Of course they have a say in the snow potential, but it is down to a lot of other factors as well!

    Oh and incase your wondering the upper air temp is -9c on Friday afternoon. 7c would suggest a lapse rate of well... A drop of a degree every 300feet. Over the top

    Here's a few GFS variables for Friday morning, it might be a short affair but it will feel pretty darn cold in the north!
