Wednesday looks like a nice ridge between two sets of fronts, so I reckon it’ll be nice and thermic earlier on, perhaps with increasing cloud as the day wears on.
Saturday looks pretty unstable and showery, as does Sunday, but at this range, it’s difficult to be sure. As ever, instability is good for thermals, and if there is sun on the ground at this time of year, it’s likely you will be able to stay up, even if that is until the next shower comes along!
