High pressure next week

Early next week high pressure becomes centred over the UK. It keeps the weather settled and during the days it should feel pleasant. The nights are likely to be chilly and patchy frost remains a risk. By Wednesday daytime temperatures could be reaching 17C (63F) in eastern England.

Through the second half of the week the high pressure centre may migrate eastwards into the continent. If that happens temperatures could rise further as a warm south or southwesterly flow develops. However, it also leads to the possibility of disturbances from the Atlantic beginning to push in and bring the risk of a return to more changeable weather.
