A low pressure system that moves in from the continent (that doesn't happen often, does it?) shown in FI that would bring some warm, humid temperatures with it. Temperatures potentially up to the mid-20s for England, Wales and Scotland, maybe even high 20s locally with widespread 850s of 12-14C and I imagine we'd get lots of really intense thunderstorms! I wouldn't mind that, looks interesting. A hell of a lot better than these Atlantic lows, so boring!
Unfortunately it's in deep FI, anyone else think it'd be fun?
