Upper trough will slide southwards down the North Sea during Friday and Friday night, the associated cold pool creating an environment with steep mid-level lapse rates and marginal CAPE. Numerous showers will affect Scotland during Friday daytime, these extending down North Sea coastal counties on Friday night. A few isolated lightning strikes will be possible.


Elsewhere, scattered showers are expected to develop over Wales / Midlands / CS + SE England on Friday afternoon/early evening, but marginal CAPE and capping at 700mb suggests lightning activity is rather unlikely.
