Fri 15 Aug South West England

A changeable pattern at first with spells showers, which may be locally heavy and perhaps thundery, but there will be drier interludes. Showers will tend to ease through the early part of the period as high pressure builds. Much of England could still see warm or very warm temperatures for at least a couple of days and there is a possibility that the heat could last further into the week, especially in the south. Beyond this high pressure will likely continue to build from the Atlantic leading to plenty of fine weather with perhaps the odd heavy shower or thunderstorm. Meanwhile a rather more changeable and breezier theme will continue further to the north but it may become increasingly settled. Temperatures will probably continue to be above normal.
