There is a small risk of a few isolated heavy showers developing late afternoon into the evening hours in eastern England, moving offshore to the North Sea. Otherwise, pulses of showery rain will be possible through Tuesday night across parts of England and Wales, and while the risk of lightning is probably quite low a few isolated strikes may be possible. The risk appears greatest towards southern and eastern areas, where there is scope for convection to be rooted within the boundary layer. Low-level winds will become backed later in the night, and this may increase the risk of an isolated tornado.

Behind the cold front, cold air overspreading warm seas will help generate scattered showers through the night, albeit probably restricted in height due to ridging.
