Met Office 14 day Long Range Forecast for the UK
see graphic, click here:
The end of July and into early August will typically be dominated by a northwest-southeast split. Northwestern areas will probably experience rather breezy conditions with cloud and some outbreaks of rain or drizzle as weakening Atlantic frontal systems attempt to push eastwards across the UK.
Toward the south and east it will tend to be drier and brighter much of the time, although there is also the small possibility of some thundery showers spreading in from the nearby continent at times.
Temperatures during this period will probably be close to or slightly above average overall, with the likelihood of some very warm conditions developing in the south and perhaps parts of the east at times.
