  1. the last time for each month the average daily maximum was 1c or more above average - for my part of the world 

    January - 2008, then 2007

    February - 2017

    March - 2017, also 2012 and 2011

    April - 2014, then 2011

    May - 2017, then 2016

    June - 2016, then 2014

    July - 2014, then 2013

    AUGUST - 2004, then 2003

    September - 2016, then 2014

    October - 2014, then 2011

    November - 2015, then 2014

    December - 2016, then 2015.
     
    Just shows how bad the run of Augusts has been, interesting about January though as well. 

     

  2. Interesting observation today - Great Dun fell has a good covering of snow above 1500ft on the top like many other mountains in Cumbria,

    the temperature today reached 10.5c at 2800ft obviously with blazing sunshine and very little wind.

    The Dewpoint mid-afternoon was -16.3c giving a humidity reading of 13.5%

    Now down at this altitude, even a foot of snow would melt within about half an hour under blazing sunshine and 10c

    Is the low humidity and resultant dewpoint the main factor in preserving the snow in such high temperatures? What is the warmest it could get before you ended up with a rapid mega melt?

    Cumbria tends to get the snow when no-one else does. We have our own micro-climate so to speak. Our best snowfalls come courtesy of frontal features with an onshore SE light feed, usually when we have had cold air at the surface and a slow moving warm front moving in from the Irish Sea, stalling in situ. We tend to have little marginality in these situations. We don't do well in northerly airstreams unless there is a marked trough or frontal feature. This morning was very irritating, had the precipitation been a little heavier and further west we would have seen conditions like occured in Pennine/Peak District, alas not to be.

    The last heavy snowfall we had (we just missed out in late March 13 - coastal regions saw copious amounts..) was 26 Jan 2013, 7/8 inches from a frontal feature moving into cold air, it quickly thawed. Can't remember the last staller front, ages and ages ago, most have moved through and produced milder conditions quickly, late Dec 2010 did this. Feb 5/6 1996 which I go on about all the time produced 18 inches.

     
     
     

    Cumbria is a very large county...

    It easily has the snowiest lowland parts of England (along with snowiest part of the uplands) looking at the met office climate maps, (possibly on par with Northumberland/Durham)

    Up here the SE feed thing is useless, creates a rainshadow effect with no evaporative cooling or anything to suppress the temperatures. ends with light sleety nothing

    recent decent snowfalls here are  17th Jan 2016 - 9cm, 29th Jan 2015 - 6cm, 21st Jan 2013 - 11cm, all from totally different directions / setups i think.

    Surprised its that high. It was quite a chilly start, but yes we've had consistently very mild weather since the 7th, the outlook is for more nearer average temps which will help to prevent it rivalling last December, but another very mild one looks on the cards.

    We've had some very mild second halves to December since 2010, becoming a trend.. and not a nice one from a personal perspective.

    Real pity we couldn't exchange the outlook for the 23-26 Dec 2016 with that of 23-26 Nov 2016 which was cold with long lasting frost, snow on the fells. What's the betting we see a colder easter than christmas yet again!

     

    10 / 19 days have reached double figures, several of them 13-14c. a fair few of those days the minimum temp was not much short of the maximum. 

     

    7th for example max was 13.0c min was 11.0c

     

    December is currently 3.4c warmer than November

    I wouldn't have called it very mild, here we had three days touched 12C otherwise single figure maximums the rule and some chilly nights - though only one air frost. Mean is on 6,4C about +2C
    Nothing particularly mild for several days yet.

     

    nothing mild? For here the overnight lows forecast for the next few days are 5c 4c 5c 5c

    December average low here is 1c, so thats 3-4c above average still

    The overnight lows are almost the same as what should be the daily high (6c)

    very very mild to me. 

    Mean here is 7.4c which is 3.5c above average. 

  6. Just looked through all my data from this month and thought id compare it to December 2015 which had an anomaly of 3.9c above average here.

    Now last December was by far the mildest by a huge margin i think, back to god knows when. (warmest on record since 1910 UK and warmest since 1659 CET)

    scarily the anomaly this month is sitting at 3.5c and is not far off that 2015 figure at all. 

     

    Anyone else got such a close match between this year and last?

  7. No ice days yet here but we are in the middle of a rather severe frosty spell

    A while since the countryside / roads etc have been this frozen, lasting all day in most places barely thawed by the sun. 

    hoar frost in valley bottoms and frost pockets

    -4c / -5c in the lower lying valleys has been achieved a few times in the last week or so.

    stunning early winter weather

    But it doesn't, that's the whole point. The shortest day is the 20-22nd day of winter in the meteorological sense, and the 1st day of winter in the astronomical sense. In no sense is it the middle of winter.

    Unless your post is describing a new hypothetical season!

    i know, i was just trying to make it clear what the OP was trying to get at. 

  9. I think seaskayaker is also basing it on day length over anything else, so...

    The shortest day marks the middle of winter. If winter was still 3 months long, then December 21st would be the 46th day of winter.

    Therefore winter would begin on the 5th November and end on the 5th February.

     

    is this what you mean seakayaker?

  10. i get what seakayaker is trying to say, and think it best fits a phenological model whereas the seasons can greatly shift depending on the year to year weather patterns etc.

    Autumn can start in August when the first berries ripen, fungi start to appear even some trees start to turn.

    The period now is arguably transitional into winter - many trees are now bare (marking the end of autumn) and here at least we have had snow/frost for the last week or two. 

    likewise spring can start in mid February or as late as mid April (2013 for example)

    isn't that more typical of August oop norf? may and June I always thought were better with the east winds and high pressure, where as south, August is warmest, May and June pants

    A months rain in one day hardly consists of a "typical August" You are right about May and June but the extent to which August has become wet in recent years is phenomenally beyond the climatic norm.

    I've never rated August, on average its far duller than May, June and July, symbiotic of how distant the longest day is becoming...it is also far wetter, indeed it can be one of the wettest months of the year. Westerly airstreams traditionally gain the upper hand. In recent years we have seen a more southerly tracking jetstream which is the key reason why conditions have often been average temp wise at best - with the azores high forced to stay in situ, this wasn't the case during many of the augusts of the 90's and 00's until 2007 when we saw a marked change.

    There were very poor Augusts in the 80's though, 1985 and 1988, 1987 spring to mind, 1986 was exceptionally cool as well. The cool wet dull August followed by the mild dry sunny September has become a regular occurance, but sunny dry days with the light fading at 7pm are a waste compared to ones when the light doesn't fade until around 9pm. There is a rapid rate of daylight loss through August and September more especially. May and June are far better months than August on average here, yes not as warm by a long chalk, but often much drier, sunnier and settled.

    i think most people are missing the point - yes August is the wettest / most westerly month of summer, but likewise october / novemeber / december are normally very wet and westerly. 

    However we have had the likes of December 2010, October 2015, November 2011 that are in complete contrast to what you would normally expect.

    add the likes of February 2011, March 2012, April 2011 and 2015, May 2016, June 2014, July 2013, September 2014 and August stands out like a sore thumb as the only month incapable of producing any anomalous settled and warm conditions in the last 10 years.

    Low-mid 20s for most of England over the next few days. Lake District weather tends to peak early in May and June. 

    im sorry but the climatic average high in the Lake District for August is 19c (Keswick) and 20c (Ambleside) 

    As i said above, every August since 2005 has in a way been below average at Keswick. 

    Yes our weather is best in May / June / July BUT August is so so so much worse in comparison than it has ever been recently.  

  14. At Keswick, my local Met Office station, the August average to 2005 was 19.9c

    since 2005 the highest mean maximum has been 19.8c, so in effect every August since has been below average.

    This has actually knocked the 30 year average maximum temperature down 0.5c to 19.4c just because of the Augusts 2006-2015.
