"Temperatures around 22°C in the north..."
I don't see Edinburgh as "the north", it might be north of the southeast (if that makes any sense), as are most places are.
"The north" to me now that I'm back in Scotland would be Caithness and the northern Isles.
I know I'm being super-critical of him here, but if it winds me up then it would be even more irritating to anyone living in Shetland, which is the north, and where temperatures on Wednesday will certainly not be 22°C.
"Still a north or north easterly wind across the north..."
But surely that's a north or northwesterly wind across the north?
"Best of the temperatures further west, south Wales, southwest England 24 or 25°C, but it will be cooler across the north..."
But what about the 25°C for Glasgow/Edinburgh, the highest temperature that you've put on your map? (i.e. "the north")
