A rather cloudy start with patchy rain or showers. However, becoming warm with sunny spells developing along with a scattering of showers. Any showers could be on the heavy side. Maximum temperature 22 °C.

Outlook for Saturday to Monday:

Sunny spells and scattered showers on Saturday and Sunday, any showers possibly heavy and thundery. Rain or showers possible on Monday.

Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. Tuesday will likely see a continuation of heavy, perhaps thundery showers, although the focus may be more across the north and east by this stage. 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 with some humid conditions possible at times making it feel particularly warm in any sunshine. 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.
