  1. I have been staying in Tideswell this weekend and wondered how you'd find it today, definitely a very warm day in those parts. Even up at 320m where I was it was still very warm and didnt feel much cooler than when I arrived back home.

    You'd have hated it here though, at one point the temperature was 27.6C with a dewpoint of 20.2C. The dewpoint was the highest Ive ever recorded and it just felt horrid.

    It's not been too bad in the daytime, just about bareable. But I've came on here to whine about the nighttime temperates, which are refusing to drop much below 18C. If it doesn't drop much further then surely this is one of the hottest nights ever? Absolutely vile.

  2. Philip Eden had a discussion of this in his book Weatherwise, noting that temperatures in the London area were highly inconsistent with falling sleet or snow, but that the reports of snow on high ground, including Skiddaw, were probably genuine.

    TORRO has a list of lowest temperatures recorded in each summer month:

    Incidentally, sleet and snow have been noted at low levels in northern England on two occasions since the famous 2nd June 1975 event- 7th June 1985 and 3rd June 1991. There was a snow event in early June 2009 which was confined to high ground only.

    Not northern England, but I think someone on a different weather site reported snow down to 400m in the Brecon Beacons earlier this month!

  3. Even last June/1st half of July was closer to "shades of 1976" than this summer... by far. Now people are calling 1 day of 25°C a "heatwave" it shows how desperate we have become.

    There was once a time when a "heatwave" was at least 3 consecutive days over 30°C and not just in the SE. Even in my part of Derbyshire Peak District last June we managed a lot of days reaching 25°C.

    I don't think it got to 25C at all last June and July? At least not above ~300m. It reached 25C in May though.

  4. Wow compared to Peterborough you've had a flood because we have seen half of that total.

    Jan = 32.9mm

    Feb = 33.0mm

    Mar = 2.0mm

    Api = 3.7mm

    May = 6.3mm

    Total = 77.9mm

    Your spring totals are incredible. At this rate, you'd record less than 250mm this year, which is enough to qualify Peterborough as a desert.

    Buxton, around 15 miles to the north of me:

    Jan - 92mm

    Feb - 166mm

    Mar - 13mm

    Apr - 13mm

    May - 58mm

    342mm. If every month had equal average rainfall, then we should be up to about 500mm already.

  5. Here's a recent one which occurred in Adelaide in early 2009:

    "On the morning of January 29, an exceptional nocturnal heat event occurred in the northern suburbs of Adelaide around 3 a.m. Strong northwesterly winds mixed hot air aloft to the surface. At RAAF Edinburgh, the temperature rose to 107°F (41.7°C) at 3:04 am. Such an event appears to be without known precedent in southern Australia."

    I skimmed through your post and only read 'Edinburgh'. Now that temperature really would've been incredible.

    There is a great chance of Tornadoes today and would love to be positioned just SE Of that, as you say the shape is fantastic.

    Here in the SE The Cumulus Field is better than I expected with some really nice Convection going on towering up and then turkey towering and splitting off. Temperature needed to set something off has been reached.

    Aaaand I'm just the SE (more SSE) of it! Despite it looking rather white and innocent, the sheer height and size of it makes up for that - it's rather imposing. I've got very little knowledge on convection, so apologies for the lack of technical terms.

  7. 2003? It was mid 30's almost everywhere.

    I think it came close, but didn't quite reach 30C. I've never taken official recordings though, maybe Terminal Moraine can help as I reckon he lives close to me, and at a similar altitude (I got the 'no 30C since 1990' statistic from one of his posts).

  8. When it comes to 30+ C, 'fraid I'm squarely in the loathing camp too. :p

    I'm pretty sure it hasn't hit 30C here, about 70 miles north of Coventry, since 1990 :). June snow, July maxes as low as 9C, 5am scrapings of ice off cars in the valleys in August and 8 days of persistent fog / low cloud is a british summer at it's ugliest. However, I think the altitude could be to blame here, which Coventry simply doesn't have.

  9. The thing that makes Shropshire, The Wirral and nearby areas seem so banal when it comes to precipitation is that hefty downpours are far less common there than in drier places such as East Anglia and the South East. I'm sure what little rain it receives, it mostly arrives in drizzle, far less heavy than west of the Welsh mountains. And yes, keeping the cloud.

  10. This isn't using statistics as such, and I'm giving score bias to the earlier months as it is normally expected that they're warmer.

    December:

    Snow - 10/10 - 60cm of level snow going into the start of the month? 24 days of lying snow? Yes please!

    Maximum Temperatures - 10/10 - A -6.6C max in Buxton. While it was -7C in the early afternoon there, it was -11C in a nearby valley, according to the same car thermometer, so I'm assuming an inversion lasted all day, meaning that astonishingly low maxes were possibly recorded. There really needs to be a Met Office station in a Pennine or Peak District valley.

    Minimum Temperatures - 10/10 - Not too impressive on the hills, but a roadside thermometer in a frost hollow near Alfreton, between Derby and Chesterfield, recorded -20.5C, which warrants a 10/10 for the entire month on it's own. Truly nostril-hair freezing stuff.

    Sunshine - 7/10 - Cloudy after Christmas but some wonderfully clear days with little wind.

    January:

    Snow - 3/10 - Snow fell on around 2/3 days, but it was merely frontal snow, so was followed by mild air and never lasted the entire day.

    Temperatures - 6/10 - There was a distinctly dry cold in the anticyclonic spell at the end of the month, bringing an ice day or two.

    Sunshine - 3/10 - A very cloudy first half. 38 hours of sunshine.

    February:

    Snow - 1/10 - No settling snow at all below 200m, and only temporary coverings above that. Truly dire.

    Temperatures - 2/10 - Unlike the rest of the country, 10C was only reached in Buxton in the last week of February, although many 9C maxes were recorded. However, temperatures failed to get below -1C at all.

    Sunshine - 2/10 An average of one hour per day, most of which was recorded on just a few days, with a week of no sun whatsoever and omnipresent fog.

  11. The 18z is striking fear into me, a very mild March with high pressure for weeks on end after several months already of below average rainfall here, we need this high pressure in 2 months time not now :lol:

    Below average rainfall?! There's been 166mm so far this month just 50 or so miles to your North East!

  12. So, wait - cloud = global warming?! Honestly?!

    Not at all, he means that despite cloud, which would be expected to suppress temperatures in the summer, the month was very warm. But having said that, global dimming, the increase in global cloudiness, is a negative albedo that helps to offset higher global temperatures by responding with a cooling mechanism, increasing stability.

  13. "At Katoomba (1,010 m) summer daytime temperatures are usually in the 20s with a few days extending into the 30s (Celsius). Night-time temperatures are usually in the teens. During the winter the temperature is typically around 12 to 13°C in the daytime with −3°C or so on clear nights and 2 to 3°C on cloudy nights. There are two to three snowfalls per year. In the lower mountains, however, the climate is significantly warmer."

    So that's very exceptional. An equivalent would be the far south of England, which has a similar summer climate going by that description, having snow on 20th June.

    I'm sure most will be tired of the "this spell has been exceptional!" talk, but we can clearly see that from this, the November/December cold spell has been colder than the January cold spell of this year. After that who would've thought that in terms of severity of cold, it would've been beaten in less than 12 months time?

  15. Past Manchester, a couple of miles West of the Pennines. Snakes pass was impassable when we went, 4x4's were getting stuck.

    Went before Christmas. :)

    Ah yes, that would be West Derbyshire rather than the West Midlands, which are quite a distance away. It got far, far worse after christmas too! Drifts of up to 10 feet at 500m on the Cat & Fiddle road was perhaps the most impressive feature. I couldn't believe those heights/depths myself till i actually saw them. The actual depths weren't really measurable because they were so inconsistent but i'd be surprised if they were less than a foot at any point between new year's eve and mid January.
