Much of this period will be unsettled, with low pressure systems tending to dominate the overall pattern. This will mean showers or longer spells of rain will affect much 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 form in the vicinity of the UK. Later in the period, there may be some longer spells of drier weather that develop, 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.

There are likely to be some drier, more settled interludes though, particularly at the start of the period. Temperatures are likely to be close to or a little above average overall.
