Looks like the GFS stops the really exceptional uppers from reaching us on Wednesday as high pressure is closer by, the weaker low over Biscay doesn't quite give the plume that push we need for record breaking territory (it may be saving it for a later point!)
I think it's a good trade off though as something like this could bring more sustained heat. Looks like the chances of 1 very thundery day are also quite high too. The 20C isotherm now begins to make inroads on Thursday instead.
edit: the unusual synoptics mean even somewhere as far NW Stornaway could see some decent thunderstorms , when was the last time a plume really delivered some big storms for this area? May 2006?
Still high uncertainty over smaller details at this point.
