Difficult to pin down any specific area for lightning activity, as there is a fairly broad but low risk in many areas, though some hints in NWP guidance of low-level convergence forcing a line/area of slow-moving torrential downpours in East Anglia during the afternoon and early evening hours. Marginal instability and rather unimpressive lapse rates suggest lightning might be quite isolated or sporadic (probably not worthy of a SLGT), but a very low-end SLGT has been issued to highlight this area a little better - the net result probably some heavy showers with little lightning. This also dependent on sufficient cloud breaks for insolation. Here the main concern is localised flooding. A few funnel clouds or a weak tornado will be possible with this activity.

The deepest convection will likely be found over SW Ireland with closest proximity to upper vortex, though this possibly moving through slightly out of sync with the diurnal cycle perhaps.
