Upper trough will migrate eastwards across the British Isles on Wednesday, with cold mid-levels atop SSTs generating some instability. Squally showers will run eastwards, some with small hail, gusty winds and sporadic lightning - moreso close to west-facing coasts. Increasing heights ahead of the next frontal system will limit convective depth from the SW, with showers here becoming increasingly isolated with time.
