Well it's fair to say, if, and that's a big IF, this GFS 6Z verifies, we are on the cusp of a major and prolonged heatwave.
As is the case in winter when we see Nirvana cold charts, this is just one run, and is so drastically different to the 0z, it must not be taken seriously, but very much in isolation at this stage.
I fully expect this to be an outlier, as was yesterday's 12z ECM. But the fact that these outliers keep being thrown out, not by one model, but by multiple models, could suggest that something like this is possible.
The next few runs will be important to see if we can get some sort of cross model agreement.
If we do, I think there is a greater than 50/50 chance that we are possibly about to experience the hottest weather this country has seen in our lifetimes, and possibly quite prolonged too.
Time, as ever, will tell.
