Sun 20 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. 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.
