Outlook for Thursday to Saturday:

Remaining largely dry, sunny and hot throughout. A few showers possible later Friday and Saturday but most staying dry. Light winds initially but a freshening easterly breeze developing by Saturday.

Southern areas are likely to start this period very warm, locally hot in the southwest, with heatwave conditions persisting. Somewhat cooler to the north and cloudy with periods of rain and drizzle in the far north. Into the following week, high pressure is likely to build to the north or northwest of the UK, though its exact orientation is rather more uncertain. This would bring a lot of dry weather for many areas, though perhaps an increased chance, relatively to previous days, of showers or thunderstorms in the south. Temperatures probably moderating a little, though remaining above average for many areas.

High pressure is more likely than low pressure for much of July, probably bringing settled and drier conditions. Occasionally this dry and warm weather could be interrupted by outbreaks of rain and stronger winds, which will be more probable in the north or west. As is typical for the time of year, there is a risk of heavy, thundery showers during any warm spells. The signal for predominantly settled weather becomes increasingly unclear towards the end of July. This means unsettled interruptions may become more common, but confidence at this range is low. In any case, temperatures are likely to be above average overall, with a greater than normal chance of hot conditions developing at times, especially in the south.
