  1. Here's a screenshot of the Lightning I tried to film on Tuesday night. It's a shame it didn't stay clear for long as it was quite a light show in the east - though I'm glad the storm was not overhead! Yesterday turned out to be a very warm and humid day with a hazy end of summer feel. Last night was largely clear though I was able to see distant flashes to the south - presumably from the storms near the aisle of Man. Cooler and cloudier today.

  2. I can only imagine what the carnage that's going on in Edinburgh/Fife - constant lightning, heavy rain, a little bit of hail, gusty winds and lloud thunder. The only thing missing is a tornado! I wonder what's contributed to such an impressive that seems to have intensified after dark. Here it's a warm night but the breeze has picked up a little with clouds moving quickly to the west. There's been constant flashes to the east for much of the last two hours with occasional brighter flashes.

  3. Seems to be lightning flashes to the east every few seconds. I can't tell there's cloud or haze overhead and whether that's reflecting the the Lightning from the storm over Edinburgh. Quite remarkable that the flashes can be seen from Ayr - it must be some storm over Edinburgh.

  4. Lovely night tonight and it looks like we could be in for an interesting couple of days. Last year Glasgow reached 29Cand the year before it exceeded 31C and with 29C forecast for tomorrow it seems summer 2020 might join the list of very high temperatures in Glasgow. Like last summer it hasn't been anything special in terms of temperatures and sunshine so far but when we do get a spell of hot weather it tends to be very hot. 

    I've just read the convective weather forecast which is interesting to say the least. Last year was very active in terms of convection and 2018 had a couple of decent storms but the last proper storm I can remember was 2006. I don't think I've experienced a supercell or a severe thunderstorm with large hail and gusty winds although I might have seen a funnel cloud once. I doubt there'll be widespread thunderstorm activity tomorrow but where they do occur they could be intense.

  6.  

    The 2010s had no shortage of significant weather events in the United Kingdom. The decade began with some of the most notable winter weather in decades including the historic cold of Devember 2010. And the decade ended with new monthly maximum temperatures being set  in 3 months, including 20C being reached for the first time in February and the all time UK maximum temperature of 38.7C in July. The decade droughts, at the beginning of the decade and in the summer of 2018, record rainfall and significant flooding - most notably in 2013-14 and December 2015. There were some remarkable periods of weather including the unseasonable warmth of April 2011, December 2015 and February 2019, and cold of March 2013 and the very stormy and wet winter of 2013-14. The decade also saw some significant storms including ex-Hurricane Ophelia and the gales of 2011-12. And there was an abundance of notable warm weather events and records. After a decade of a variety of extremes and records it's difficult to choose which event stands out the most.

    Personally, breaking the winter record maximum temperature record so emphatically was particularly exceptional, possibly more so than breaking the all time UK maximum in July. The historic cold of late Nov-December 2010 personally stands out the most and will probably stand out even more in the future in the context of climate change. Honourable mentions go to the cold and snow of March 2013, the relentless wind and rain of 2013-14, the exceptionally mild and wet Dec 2015, The Beast from the East and summer of 2018. 

    The most memorable weather events depend on your location and interest. Localised events such as snowfalls, thunderstorms and gales vary from to place so some people would regard the snowfall of Jan 2019 as locally more notable than 2010, 2013, 2018. Depending on taste some prefer more benign anti-cyclonic periods and consider a quiet and pleasant period of settled and sunny conditions as more memorable than more dramatic events. 

    My most memorable highlights from the 2010s include: the heavy snowfalls at the end of November and early December 2010. Thunder snow on the 26th November followed by a larger snowfall on the 28th. Snow showers driven by an easterly wind interspersed with clear intervals defines that spell. The 6th-8th December was especially memorable with a large snowfall on the 6th causing chaos in central Scotland followed by sunshine and very cold temperatures - a maximum of -8C on the 7th. The week leading up to Christmas - despite lacking in snow - was extremely cold with daytime highs of -3 to -5 and lows of -7 to -14. 

    The gale on the morning of January 3rd 2012 easily surpassed the much hyped event on December 8th. Maximum mean wind speed of over 58mph and gusts of 89mph were damaging and brought down a number of trees. This was the most notable gale I can remember. 

    March 2013 was memorable for how unusual it was to have a prolonged cold spell so late in the season. For a period of two weeks daytime temperatures got no higher than 6C and snow fell on almost everyday. Despite snow depths no more than an inch which melted in the sun, the fact this cold spell took place during the second half of March made it all the more impressive and changed perspectives of what is possible for winter weather in Spring. 

    Jan-Jul 2018 was a very memorable period of weather with some decent polar maritime snow throughout the winter - after mid January inparticular. 

    The Beast from the East was quite an experience, a phenomenon. The heavy snow commenced on the evening on the 27th February 2018 and continued into the 1st March. A rare red warning for snow was issued on the 28th for large parts of central Scotland. The 28th was quite a remarkable day. Frequent whiteouts of dry powdery snow accompanied by strong, bitterly cold easterlies. The maximum at Glasgow airport was -3C, considering the lowest maximum for the second half of winter in Glasgow in the previous 45 years was -1C, to record such a low temperature on the last day of winter and accompanied by strong winds and heavy snow was seriously impressive. The first of March was the latest date the temperature failed to exceed 0C at Glasgow airport. The maximum snow depth was 26cm, the highest total since I started recording in 2010 and easily one of the largest snowfalls in the previous 30 years. 

    Cold and wintry weather continued into April and Spring didn't properly get underway until after mid April. Summer arrived in mid May with warm, dry and settled conditions persisting into early June with the exception of the odd thunderstorm - one of which one of the more impressive of the past 10 years. The end of June to mid July was persistently warm and dry with 21C recorded each day from 24 June to 14 July and no rainfall between 21 June and 10 Jul. The highlight was easily the 28th June with temperstures of 31C at Glasgow airport - the highest since I'm at least 43 years - and just under 32C at Glasgow Bishopton. 

    Other memorable events include the continuation of the Big Freeze in January 2010. The second half of January 2015 was very decent with two decent falls of snow each followed by a week long period of settled and crisp winter conditions. March 2012 was very memorable for a record breaking warm spell with temperatures into the 20s in Scotland. May 2012 had a hearwave which broke records in Scotland, temperatures in the mid-high 20s in Glasgow. February 2018 was had some very pleasant, settled winter conditions. July 2013 had an excellent two week warm spell and July 2014 also had an excellent heatwave.

  7. The storm to the south of Glasgow looked impressive yesterday - I only saw one flash of lightning but the sky looked very dark and menacing accompanied with some rumbles of thunder. Later in the evening there was another storm just to the north which wasn't particularly intense but brought some rain and produced a couple of flashes of lightning. It seems topography is important in developing thunderstorms with the higher terrain to the south of Glasgow seemingly enhancing the storms aswell as the Campsie Fells. The hills around Loch Lomond and the Cowal Peninsula seems to be a hotspot for storms - presumably the Arrochar Alps and the Lochs create a suitable environment for convection.

  8. Maximum of 29C which is the warmest in July since 1984 for Glasgow airport. Not a repeat of the 30+ last year but still among the warmest days in my lifetime and I suspect we'll see more 29+ days in the coming decades than we've seen over the past 20 years. Last year was the first since 1995 to reach 29 and one year later it's happened again. It clouded over a buit this afternoon which perhaps limited temperatures. This year has been the opposite of last year which saw a quick changeover from a cold winter to a warm summer. This year has been much more up and down with alternating spells of warm/cold dry/wet. However this year hasn't been without interest with exceptional record warmth in February, a notable warm spell in April - this summer has already produced two exceptional heatwaves in parts of Europe - continuing a trend over the past few years. The extent, regularity and ease of records being broken is disconcerting and are a sign of things to come. To have 20C+ in winter and com close to all time record today should be cause for concern. It seems the climate system is in flux and the volatile nature of the weather in recent years has almost become normal - the contrast between the beast from the east and record warm in February is an example of the extremes and lack of middle ground in our new climate. 

     

    The all time UK record stays though the July record has gone and Edinburgh had a record high (a year after Glasgow possibly broke it's own record). Temperatures in the high 20s and low 30s are just about bearable but I wouldn't want much more than 1 day of such temperatures (low-mid 20s are fine). Despite the heatwaves, it's hasn't been a great summer (last year was better in terms of prolonged warm, sunny, dry conditions with little humidity). 

     

    The thunderstorm the other night failed to live up to it's potential here (a big standard storm with a few rumbles and one flash of lightning). July 2015 was similar with little activity here - it seems homegrown daytime thunderstorms are more reliable than overnight storms that lose energy moving north. for producing  It seems the east has faired better this year fir storms (I wonder if that's to do with steering currents, a more favourable atmosphere for storms, factors such as topography) with the lothians and Fife getting the brunt of the storm. It just goes to show that no two storms are the same and one or two factors can determine how intense and thunderstorm becomes and where they occur. Tuesday night here was more notable for temperatures dropping no lower than 19C.

     

    I expect tonight will be similar with more activity to the east. Given the prospect of severe thunderstorms I'm probably glad it'll miss here but hopefully a good light show here and those who are in the firing line enjoy the storms safely and post pics and videos. I can't recall experiencing supercell thunderstorm (I wonder how this set up compares to past events like May 2006) and I'm not aware of too many supercells in Scotland. I do have a few questions about tonight: how do you identify a supercell to ordinary storms, where in a supercell are tornadoes likely to the form, other than supercells are we looking at short-lived scattered single-cell storms or multi-cellular storms. 

     

    Currently it's a pleasant, but humid, evening with largely clear skies other than some patches of speckled clouds (which I presume are signs of instability). I think I. An see the anvil of a cumulonimbus cloud to the SE. Hopefully it'll stay clear enough to see these storms from a distance.

  9. Quite remarkable weather. 29C at Glasgow airport only the 3rd time in over 20 years (last June had two days of 29C or more). Might still hit 30 which would be incredible though the all time record is unlikely. Quite astonishing weather in Se England and other parts of Europe with records going. It does make you wonder what it will take to beat the Scottish record. It's much harder to get temperatures above 90f here than jt is further south- it would require an exceptional set up. With the effects of climate change evident in record breaking temperatures it seems it's only a matter of time before a new record is set. I wonder how hot it can possibly get in the right set up - i would imagine we could get close to 35C.

  10. It appears we could be in for a lively night. Most of the more memorable storms I've experienced were before I joined netweather - although last month and last year provided some storms but nothing on the scale on events like May 2006 - and as a result my storm knowledge is incredibly limited. I'm more curious about storms than I used to be but I'm not the biggest enthusiast of storms and still a little apprehensive about the threats they pose - though I do like spectacle of watching of lightning (especially from a distance). I have no idea what to expect tonight - I suspect there'll be an hour or two of heavy rain and some rumbles of thunder but nothing too severe. Past experience would suggest storms either pass to the east or west or lose their energy before reaching here. I hope to see some lightning but would rather not have experience anything severe - at least not overhead. Talk of tornado potential is exciting if a little disconcerting and I don't quite understand the nature of this set up and what mechanisms conducive to tornadic activity and other storm phenomena - I'm still grasping what terms like elevated storms or MCS mean. It would be great if some more knowledgeable members can explain what could of set up we're in, how it compares to past events and what conditions to expect.

    It's certainly going to be interesting to see how the next few hours pan out.

    Last week we created chart 1, now a week later chart 2 shows the 3 broken records. The UK started February with an overnight min of -15.4c  at Braemar. What a month! 

    I wonder if this is the first month to have a high of over 20C and a minimum below -15C. Also Scotland had a record high minimum of nearly 14C - a range of almost 30C in terms of minimum temperatures!
