Cloud thickening with rain moving eastwards on Saturday.
This Evening and Tonight:
Showers will fade during the evening with winds becoming light. Clear spells will then develop, and it will turn rather chilly. However, some thickening cloud is then likely by dawn. Minimum Temperature 8C.
Cloudy, but mostly dry start, before outbreaks of light rain or drizzle becoming widespread by early afternoon. Rain turning heavy at times, and also turning breezy along the south coast. Maximum Temperature 14C.
Outlook for Sunday to Tuesday:
Sunday will be wet, and very windy later in the day. Monday and Tuesday then dry, with light winds, and long sunny spells. Also turning chilly overnight, with frost possible.
Day 6 to 15
For most of the UK, the weather should remain largely settled through the rest of September. Most places will have long sunny spells and generally light winds. However, some mist and fog patches will form during the nights. The north and northwest will be at risk of turning a little more changeable at times next week, with some rain and strong winds possible. However it looks to stay drier and brighter in the south and east. Days will be warm for many, at least at first, but nights will be chilly with some localised frost. Into the start of October many parts are set to remain mostly settled, though some wet and windy weather is possible in the north.
Day 16 to 30
Settled conditions are expected to dominate across much of the UK through the beginning of this period, especially in the south. There should be a good deal of dry and bright weather with any wet and windy spells likely to be confined to the north of the UK. Increasingly long nights will lead to a greater risk of patches of fog forming overnight and some places may also see some frost. Despite chilly nights, any sunshine by day will give a mild feel for October. Later on in October, there is considerable uncertainty in the forecast, with a chance that some more unsettled weather may affect the UK.
