Scattered showers are expected to develop quite widely across the British Isles on Monday, beneath a broad upper trough with marginally-steep mid-level lapse rates and marginal instability. Slightly better instability overlapping with reasonable shear gives a better chance for a few lightning strikes within the low-end SLGT across eastern England. Gusty winds and small hail will be possible. Elsewhere convective depth is likely to be too shallow for much in the way of lightning.


Later on Monday night an area of showery rain will spread eastwards across southern Ireland and the Celtic Sea, and may be capable of an odd isolated lightning strike.
