Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. The first couple of days could well be particularly unsettled with heavy rain and/or thunderstorms in many areas. Into the following week, a general westerly type set-up looks to become established, with occasional weather systems moving in from the Atlantic. This means further rain or showers and breezy conditions at times, interspersed with some drier, sunnier periods. Temperatures are expected to average out above normal and whilst brief hotter and humid days are possible, the chance of prolonged heat is lower than during the last few weeks. This broad pattern is likely to continue towards the end of July.

The end of July and first part of August will probably see a continuation of similar weather to the previous week or so - this being generally rather changeable 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 would bring more in the way dry, settled weather more widely. Temperatures are expected to continue to run above average overall, with a greater likelihood, compared to the preceding couple of weeks, of very warm or hot spells to develop by mid-August, especially further south and east.
