Anyone in Devon, Scotland or London might want to follow this on the UKMO's new 0.5km radar http://www.metoffice.gov.uk/public/pws/invent/weatherradar/
A point to note, that the last strong storm in the south/south east was 18th Jan 07, and a lot of trees that would normally be felled by autumnal storms are still standing due to lack of anything for nearly 3 years. Tonight could see quite a few trees down in the south/south east.
As far as i'm aware, we don't really issue watches/warnings for scattered TS's unless there's a real risk of something severe, i.e tornadoes, lots of +ve strikes, strong conv gusts etc.
TS sferics up and down the country, mainly to the west from Scotland down to the Midlands. Also, cell nr Corby, Northants now electrified. Reports of CC lightning in Sheffield recently.
FWIW, UKMO Nae model breaks out heavy convective precipition in the London and areas SE of it today!
Do any of you use the sferic chart http://andvari.vedur.is/athuganir/eldingar ???
It uses UKMO Atd data
