Becoming increasingly unsettled through this week.
Dry for most parts overnight with varying cloud amounts, as well as some hill fog across Scotland and northern England. Skies will turn cloudier across southwest England later, with outbreaks of rain, locally heavy and thundery.
Thundery downpours developing and slowly moving northwards, with somewhat brighter and fresher weather following in the south. Cool and murky on some North Sea coasts. Sunny in the northwest. Breezy.
Heavy rain moving northwards on Thursday, with sunny spells and thundery showers following. Turning windier through Friday and Saturday with a risk of gales and heavy, blustery showers. Much cooler.
After a dry start, many places will become wet and windy on Sunday with heavy rain at times and a risk of gales, especially in the north and west. However, there will be sunny spells in some parts. For the end of April and start of May, changeable weather is likely to dominate, with a chance of showers or longer spells of rain and some periods of stronger winds, especially in the west and southwest. These will be interspersed with drier but probably short-lived sunny spells. Temperatures will most likely be near normal in the west, and slightly warmer than the seasonal average in the south and southeast. There is a chance of a shift towards drier warmer weather by the bank holiday weekend but this is far from certain.
For the middle of May, some wet & windy weather is likely, especially at first. However, there are indications of a shift towards more settled weather as the month progresses. A good deal of fine and dry weather is possible, with temperatures perhaps above the seasonal average. The highest temperatures are most likely in the south and southeast.
