Update from Tony Gilbert...
Slight Risk Gen Tstorms Ireland 12Z-21Z
Slight Risk Strong Tstorms Wales through to NE UK 15Z-21Z
Primary attention is given to Red Box as per convective map where GFS develop CAPE upwards of 400 j/kg. Partial overlay of strong upper jet stream acquires impetus to any developing cell. Though vertical wind profiles tend to suggest pretty much straight lined at all levels. Particular attention is given to blue box where dry air at mid levels overlays and imposes on the track of the occlusion. This should utilise the best potential instability.
Prime threat today will be strong convective gusts (below severe)
