Changeable and unsettled weather conditions are expected across the UK during this period with low pressure systems tending to dominate the overall pattern. This will mean showers or longer spells of rain will affect the majority of the UK at times. Some heavy rain or showers are expected in places, most often in the west. Thunderstorms and hail are also possible, as are some spells of strong winds if any deep areas of low pressure form in the vicinity of the UK. Some short-lived spells of drier and more settled weather are also possible at times. Temperatures will likely be close to average or slightly below overall, but may rise above at times in any drier, sunnier spells.

Low pressure patterns are expected to dominate at the start of this period, bringing changeable weather conditions with showers or some longer spells of rain. Conditions may begin to turn more settled and drier later in the period, particularly in the south. Temperatures are likely to be close to average, perhaps turning warmer later in the period.
