I take it you are quite young xioni ? Im guessing you don't remember 1995 or weren't around in 76 that was the best summer of my lifetime,the current heatwave is cool compared to that year.

Also not a great fan of extreme heat, 24-28C with low humidity and a breeze is the perfect summer weather for me, usable and comfortable.

A few GEFS bring some blowtorch uppers close for mid month. A worrying sight. Hopefully those orange colours will stay well south

As you say, July and August that year were both fabulous but late June also saw a notable heatwave which saw temps in the high 20s in parts of Scotland. Indeed, last week was the hottest we have had it in Glasgow in any June day since 1995 and even managed to beat the highest temperature we had here that June. I think that the often cool and cloudy first half of June 1995 skews some people's perceptions of that month a bit, as although the first half wasn't great, the final ten or so days of that month more than made up for it IMO.

Having been lucky to enjoy both 1976 and 1995 this year has a more 1976 feel to it imo but if july follows the current forecast it could well become a classic one thats talked about in the years ahead .

GEFS 00z again showing the possibility of #blowtorch #furnaceheat next week. 2m temps don't look particularly impressive but you've got wonder whether 40C is a possibility if this continues for a few weeks.

So either it’s on to something that other models don’t buy yet, or it’s got a problem with over modelling convective rainfall.

Not sure about the - symbol that appears next to rainfall at times. I'll investigate when I get chance.
