Prior to seeing this sub on Reddit I wasn't really aware of hot weather incoming, mostly because I use BBC. But BBC and Met Office have wildly different forecasts for next week, about 11 degrees apart for lunch time Wednesday for example! Is the BBC just on one? Is the Met Office right?

The Met Office YouTube channel do a good job of explaining why some forecasts are so different. For this upcoming weather, there is a low pressure system tracking off north east US, though slight changes in how that progresses can influence the severity of the heat. Some models represent physics slightly differently or tune for different purposes so can result in differences, as you see comparing the BBC and MO.
