Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. The first couple of days will likely be dominated by low pressure leading to particularly unsettled weather, with heavy rain and/or thunderstorms in some areas. Thereafter, a general westerly regime looks to become established, with occasional weather systems moving in from the Atlantic. This means further rain or showers and breezy conditions at times, especially in the northwest. This will be interspersed with some drier, sunnier periods. Temperatures are expected to average out above normal and whilst brief hotter and humid days are possible. This broad pattern is likely to continue through to the end of July.

The rather changeable pattern will likely continue through early August with spells of rain or showers mixed in with some drier, brighter days. Towards mid-August, there are tentative signs that high pressure may become rather more dominant, which could bring more in the way dry, settled weather more widely. Temperatures will likely continue to be above average overall, with the possibility of very warm or hot spells developing later in the period, especially further south and east.
