A complex pattern will evolve on Thursday, with a largescale upper trough over the Atlantic slowly approaching the British Isles, but also absorbing a portion of the Iberian cut-off upper low as it becomes stretched and pulled northwards over SE England during the middle part of Thursday daytime. The net result will likely see an increase in precipitation coverage and intensity as two frontal boundaries straddling CS / SE England, Midlands and East Anglia become engaged by the increased forcing aloft. Given the presence of a weak thermal plume advected northwards from SW France, embedded deep convection will lead to the threat of heavy rainfall in places, bringing the risk of some localised surface water flooding.
