Thu 24 Jul London and South East England

Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. Wednesday 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 or north-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 be close to or a little above average for most of the period. This broad pattern is likely to continue through to the end of July.
