,Where did that rain come from on the radar in the SE ?
I think this is upper air driven.In WV a weakish vortex has spun up on the PV streamer moving SE
across the country.
The AVN T+18 VT 06Z today has the core of the vortex displaced somewhat NE,if MetO had similar error
this wld account for the poor forecast

Rather sharp,mod heavy shower in SE London ~17Z from v leaden sky ,otherwise rather nice with TCU
around.No rain so far this morning,
