Outlook for Sunday to Tuesday:

Often cloudy on Sunday and Monday with rain and showers pushing erratically north, perhaps heavy and thundery at times. Cooler, drier on Tuesday, with sunny spells but further showers later.

High pressure is most likely to be located either over or close to the UK through much of this period, leading to a more widely settled period of weather for most, with some cool nights, but near or slightly above average temperatures by day. That said early in the period a weak showery regime may still be clearing east. Later weak frontal systems could provide some cloud and patchy rain in north-western areas at times. There is a chance of some heavy thundery showers and more humid conditions in the south too, particularly later in the period when the high pressure may begin to drift slowly to the west. However, many areas are more likely to be drier than normal with predominately settled weather and light winds.

Moving through then beyond mid-September confidence for the continuation of settled weather falls. Instead, it is more likely that there will be a return to a mixture of weather types, with spells of wet weather interspersed with drier periods. By this period it is expected temperatures will have returned to near average, perhaps slightly cooler than average in the north or northwest at times.
