  1. Thanks, I was sure that someone had done this at some point and shared it on here - now I know I wasn't going insane! But David Snow is correct that they subtract 0.2C off after all other adjustments due to urban warming (which presumably is why all corrections seem to be centred around -0.2C, more or less).
  2. Thanks as always Roger, interesting to note that we have no -3.x daily records but three -4.x ones (1858, 1904, 2010).
  3. Late again, will go for 5.5C and 60mm.
  4. Indeed, a maximum of 6°C forecast for Saturday, will easily be the coldest day I've experienced since moving here.
  5. Would quite like a downward correction on this one just so that the latest 18C day can still also be the latest 19C day!
  6. Interesting, I lived in Selly Oak 2015-2018 and didn't even know it had its own hospital! The enormous QE next to the university seems to be the centre for most things now.
  7. Just to note that, with the official data in, we have indeed set a new record of 45 days.
  8. I'm fully aware of what you're saying, so I'm not going to argue with you, other than to say that Craig is not an idiot. His crazy punts have been a custom on this forum for years and you're taking them far too seriously.

    Spring 2013

    A fascinating season, with March of course being the highlight. Down in Chelmsford we had two snowy spells. The second one (around the equinox) brought four inches of powder snow but winds were light so we didn't get any drifting. Some exceptionally low maxima for 12+ hour days, barely climbing above freezing on a number of occasions. April started off very cold with easterlies bringing snow showers and some beautiful frosts. Sunnier and warmer mid-month before cooling down again. May was consistently cool but quite a pleasant month. Very few people realise that, in CET terms, Spring 2013 was colder than any in the 20th century.
  10. Yeah, and I thought he was crazy for going for 9°C in December 2015...
  11. Not necessarily, as it depends on where the cold air is being sourced from. Given some of the unprecedented temperature anomalies we've seen over the Arctic in recent years then perhaps cold spells from direct northerlies will be far less potent than they used to be, in which case "0.8°C less severe" may be an underestimate. However, we have seen some truly brutal cold-pooling over Siberia in recent years, which many believe could be a consequence of a warm Arctic (often referred to as "warm Arctic, cold continents"). So it may in fact be the case that we see Siberian-sourced cold spells increase in severity. The remarkably cold weather we witnessed in late February and early March of this year (upper-air temperatures briefly touching -17°C; you'd probably have to go back to 1987 to beat that!) perhaps demonstrates this. And what of cold sea-surface temperatures in the north Atlantic due to a weakening AMOC? If we see cooling in the right regions then maybe this could, to an extent, negate the effects of warmer Arctic air because the water over which the air is travelling becomes colder and hence we see less modulation? The same goes for cold-and-snow events off the back of Winter depressions: perhaps marginal events see more snow whereas previously we may have just had cold rain?
  12. Summer 1976 is currently top at 23.47C. A ranked list can be found here: https://www.metoffice.gov.uk/hadobs/hadcet/ssn_HadCET_max_sort.txt
