This trough that's heading SE seems to be a rather weak
affair.Visible to the NW ,from SE London,as
a dark line St/Sc with apparently little rain on it.
The Herstmonceux sounding is incomplete but has a very steep lapse
rate near the surface.

I wonder if a tornado or two is possible,if deeper convection gets
going?
V shallow Cu/Sc here today and warm in the sun,

.... between 1500 and 1530 GMT (add one hour for local time), wind
freshened, sky overcast, with Sc mammatus and Ac above - a *little*
rain, measured 'trace' only; now (1645GMT), cloud breaking well,
sunshine returning and a lovely end to a near perfect day here in the
East Berkshire desert! (Looks like it *should* change next week - but I
shan't count raindrops until they actually fall in the gauge! I've seen
this promised rain many times before either come to nothing, or more
likely, not as much as the raw model output would have us believe.)
