Martin,

At Heathrow, showers could be seen along with TCU to be moving up from the
S. At around 1500 local one bang with a flash ( reported ) and moderate
rain - amounting to 5mms on the 18z synop. At Guildford, jist the 0.5mm with
a much weaker affair looking at the web cam. Looks as though it developed as
it moved N.
