As a surface low gradually clears eastwards from southern Scotland, the environment across much of the British Isles will become increasingly unstable during Monday evening and night as a cold pool overspreads relatively warm SSTs, creating steep mid-level lapse rates and yielding up to 400 J/kg CAPE. Numerous showers will affect Ireland initially, then spreading farther east into western Britain through the night. Hail is likely in many of the showers, along with isolated to sporadic lightning - the risk generally greatest towards W / NW Ireland, where a low-end SLGT has been issued. Gusts of 50-60mph will be possible with some showers in western Ireland.
