A wet start to the day with outbreaks of locally heavy rain. Southwesterly winds will strengthen from the south, with rain turning more persistent, although some drier interludes are possible across southeast Wales. Despite this, it will feel warm. Maximum Temperature 19C.
Heavy rain and potentially very strong winds will continue overnight, before clearing eastwards through the early hours. Turning colder later with scattered heavy and blustery showers. Minimum Temperature 8C.
Sunshine and scattered showers on Friday, these locally heavy with the risk of hail and thunder. Remaining windy and feeling cooler. Maximum Temperature 16C.
Outlook for Saturday to Monday:
Generally dry on Saturday, perhaps with some rain in the south, particularly later. Sunday uncertain, but possibly wet and very windy. Mostly dry and sunny through Monday. Rather cool.
Day 6 to 15
Strong winds may persist in the far east or northeast on Monday morning, but otherwise a much quieter spell of weather is expected during Monday and Tuesday with a good deal of dry and bright weather across the UK. It is likely to be cool overnight with frost possible in some prone areas and fog is also expected in places. Despite some sunshine by day temperatures will overall be fairly cool. Through the rest of this period any wet and windy weather is likely to be confined to the northwest with drier, brighter conditions expected across the southeast which are likely to extend to all areas at times. There will still be some cool nights but by day temperatures may well be warm.
Day 16 to 30
Settled conditions are expected to dominate across much of the UK through the beginning of this period, bringing a good deal of dry and bright weather with any brief wet and windy spells likely to be confined to the northwest of the UK. Increasingly long nights gives 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 rather warm feel. Later on in this period there is considerable uncertainty in the forecast with a chance that some more unsettled weather may become established again.
