Remaining changeable, with occasional rain or showers arriving from the North Atlantic, most frequent across northern and western parts of the UK, where some strong winds will also be possible at times. However, there will also be some reasonably dry and more settled periods interspersed, especially across southern areas. Temperatures for the period as a whole will probably be close to average overall, but there is scope for some rather warm days at times, along with occasional relatively cool nights giving the occasional grass frost.
