    Going to be a nightmare next week,will have to cancel a number of calls in the South east due to the heat tripping kit out,that is for certain. Those poor staff who work at those sites,they have had enough. No ventilation,no aircon. Appalling working conditions.

    You must realise by now that the only acceptable response for a Netweather member in the current set-up is to demand a continual increase in heat.

    If we hit the mid-forties, unless the humidity drops then we're in serious trouble.  From a biology POV, if the temperature + DP equals 77C or greater, then even fit and healthy people are at severe risk of potentially fatal heatstroke.  I appreciate that many on here seem to think that they're so macho that they could survive an industrial furnace, but, at a certain level, the body simply cannot maintain its safe temperature range.

    Wouldn’t it be carnage in here if,after the weekend, the heat was killed off by the Atlantic much the same the cold was back in March. Not looking likely but never say never

    Well I'm pretty confident, given how much squash I play in hot  weather, that I'm capable of surviving almost any heat and that I'll be posting on here for years to co

    People keep showing the GFS, but the parallel is just getting ridiculous. Yes that is the 24c isotherm almost touching the south coast.

    I think new GIFs may be needed by some.....

    I have only been posting about the GFS12Z for several days now, just to see what it does each day, as JH says pick a model and its time instigation and stick with it

    I think Leonard rossiter , if posting in here, would probably have said the same thing...

    It's just as well then that nobody here has said such a thing. Mid-forties? Temperature plus dew point of 77C? You know very well that's not remotely going to happen.

    Tbh there is no 'hot' weather forecast for my location, just general low-mid 20's warmth and my temps have downgraded slightly again.

    When the near continent and Scandinavia hot up (wouldn't bet against the latter getting more records again) we often seem to be a bit too close to Atlantic lows. The ECM has found a 2nd fresher interlude next week, and on the latest available mean from last night my 850s are still below 10C here at day 10 and are warmer off the north coast of Lapland, lol.

    It may hot up again and the trend is good, though I can't ever buy too much into what the GFS/GEFS shows beyond day 10.

    Still a fantastic summer for us though not quite as hot as it could have been perhaps, good for some I know.

    Mid-40s with high humidity doesn't even occur except in areas around the Persian Gulf. It would be impossible in the UK, and if mid-40s temperatures did occur in the UK it would almost certainly be a very dry heat - it would have to be to allow such high temperatures to be achieved.

    Don't parts of the Indian sub-continent hit 50C with high humidity pre-monsoon?

    No if you look at places like Jacobabad and Sibi in Pakistan which record the highest temps relative humidity is usually 4-8%.

    Further south east places to the north east of Mumbai can get to 40c and dew points in the high 20s. 

    Persian gulf is comfoabtly the world champion of heat indices.

    Deadly heat waves projected in the densely populated agricultural regions of South Asia

    Quote

    The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations, we project that extremes of wet-bulb temperature in South Asia are likely to approach and, in a few locations, exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.

    I wonder if there's an online record anywhere of how many heatwaves of each degree of severity are occurring simultaneously?

    This year seems to be on steroids when it comes to high temperatures over land. 

    Important to emphasise land there; the ocean surfaces are overall, as expected, some way short of what we saw during the major oceanic heat release phase 2014-16. This may actually be a part of the heatwave equation; lower ocean surface temps mean less moisture release into the atmosphere (to an extent regionally adjusted by predominant weather patterns).

    That was it - thanks Malcolm!  I think the 77C guideline was a rough equivalent to a WBT of 35C.

    What an amazing year for weather enthusiasts.First the record cold start to March then another cold spell now this amazing hot spell.It all started with that SSW event in late February.

    Im so interested in how the winter  is going to pan out too later,mega cold,maybe???

    The GFS parallel aka FV3 is still going for insane heat broaching our shores the weekend after next - it's been pretty consistent on this for a few runs now.  T300:

    It seems our weather has been changed since the SSW due to the Atlantic effectively being cut off. Would be something else if it happened right through winter. Of course it wont but still the thought.....

    Muscat in Oman is unbearable in the summer, the only place I've been that's hot I didn't like because  it was so difficult

    I did read a post by @Interitus the other day, mentioning that there was no correlation between our Summer's and the SSW. I could be wrong, but I cannot find it now.

    It does seem a huge coincidence if that's the case

    Toughest day so far this Summer,just heard tired moaning all day from everybody. One poor nurse had to be treated for heat exhaustion on one site today,she was in tears.We need a change,everything is looking and is scorched,nature is suffering,the trees are stressed,the fruit production is woeful,birds in particular are suffering,the lack of running water is a major issue. This week is going to be tough,very tough.

      Low pressure is going to keep doing its thing during the upcoming week, rolling in from the Atlantic, then hanging around to bring days of sunshine and showers with occasional longer spells of rain. Read the full update here
