A few small flakes now in Biggin, given the slow NNW movement of the Kent band, that's probably the lot for the night. 1cm gained however...can't complain.
I believe when the RFD or forward flank down draft begins to cut the warm inflow off from the circulation. Same reason outflow dominant storms rarely produce tornadoes. happy to be corrected on this however
Looked to be towards the Kenley, Warlingham direction. was pretty much isolated from the rest of the storm. We got hit hard as well but I've never had such a clear view of a one so was quite interesting to watch.
Marvellous storm just passed over Biggin Hill, constant CG lightning and what appeared to be a possible small microburst on the tail edge of the cell (large ball of rain sudden dropping and fanning out so I'm going to make the assumption)
