A ridge of high pressure will continue to build across the British Isles bringing largely fine, dry and very warm conditions in the south.
However, a small amount of instability will linger across eastern parts of England into the afternoon (CAPE up to 500 J/kg), and may be enough to help generate a few isolated heavy showers. Lightning is considered only a very small risk <10%, however cannot be ruled out in any heavier showers.
Shear remains weak, and any isolated showers that develop will be slow-moving, however rather limited in terms of updraft life-cycle. Showers will pulse and generally weaken quite quickly. Very localised heavy rain will be the largest threat.
