Fine and dry with long sunny periods.
After a rather cloudy start, especially in the west, it will be a mostly dry day with warm sunny spells developing. Winds becoming breezier through the afternoon. Maximum Temperature 26C.
Cloud increasing through the night and generally quite breezy, especially near the south coast. Rain arriving into the northwest of the region around dawn. Minimum Temperature 14C.
Rain, heavy at times, moving eastwards across the region during the morning. Improving from the northwest during the afternoon with all except Kent fine and dry by evening. Maximum Temperature 22C.
Outlook for Friday to Sunday:
Friday, mainly dry, bright and breezy. Saturday, probably mainly dry with some bright spells, perhaps cloudier later. Sunday, cloudy, windy with scattered showers. Temperatures generally warm.
Day 6 to 15
Heavy persistent rain and strong winds are likely at times on Sunday in northern, central and western areas, with the southeast probably staying dry. Next week will tend to stay windy in the north and west with a fair amount of rain here but also a few brighter and drier interludes. There will probably be a good deal of dry and bright weather in the south and east, with only brief interludes of thicker cloud and rain. As a result, this part of the country may well become very warm and humid again. This pattern is quite likely to continue into the following week, with warm dry weather predominating, especially in the south, and longer spells of rain and wind more likely in the north.
Day 16 to 30
During this period it looks likely that the weather pattern will only change slowly. High pressure will tend to dominate at the start of this period, with southern areas perhaps seeing the driest and brightest weather. Further outbreaks of rain and strong winds may move across the north, and perhaps sink southeastwards at times. Into September, confidence in the forecast decreases. However, we will probably see some longer dry and settled spells at times, these perhaps becoming more dominant in the north and northwest. Temperatures are likely to be generally warmer than average, but as we go into September there will an increasing chance of some chillier nights.
