Under the influence of an upper trough, some isolated lightning may be possible from either scattered showers or close to the frontal boundary, given some marginal instability. A funnel cloud or weak tornado would be possible with this activity, especially near coasts.
... SW ENGLAND / MIDLANDS / EAST ANGLIA ...
Late afternoon into the evening, increased forcing arriving from the south as the mean flow backs, close to the quasi-stationary cold front, may provide the focus for an increase in convection. Some uncertainty over the exact positioning of the front, and hence areas affected and also whether convection will be deep enough for lightning. Have issued a broad LOW threat, but it is possible that no lightning activity may occur. The focus generally shifts to East Anglia for Monday night.
