Unexpected cloud burst coming through Rayleigh and back into Southend-
on-Sea at about 17:30 this evening, roads were completely awash.

While convective cloud tops were generally only around 9000FT there was a
fair bit of CAPE. That combined with a sub-zero layer between 6000 and
9000FT and enhanced upper forcing down the eastern side of the UK led to
some fairly lively showers during the afternoon.
