UPDATE 04:12 UTC SLGT extended farther N across East Anglia

Large upper trough will sit across the British Isles on Tuesday, accompanied by cool mid-levels. Diurnal heating will generate 300-500 Jkg-1 MLCAPE, with scattered showers and a few thunderstorms likely, especially within the SLGT. Areas of low-level wind convergence will provide the main focus for deep convection, in the absence of any notable DLS. Here a couple of brief funnel clouds will be possible. Some small hail is possible from any stronger cells.

Later on Tuesday night, a cold mid/upper level pocket approaches from the NW towards NW Ireland / NW Northern Ireland. An uptick in shower coverage is expected through the early hours of Wednesday, and with steepening lapse rates a low chance exists of some lightning with this convection.
