This period is likely to start out unsettled, with low pressure dominating the pattern. This will mean showers or longer spells of rain will affect most of the UK at times. Some heavy rain or showers are expected in places, most often in the west and north. Thunderstorms and hail are also possible, as are some spells of strong winds, especially if any deep areas of low pressure develop and affect the UK. Later in the period, there may be some longer spells of drier weather that develop, especially towards the south, with more in the way of sunshine due to higher pressure. Temperatures will likely be close to average or slightly below overall, but may rise above at times in any drier, sunnier spells.
