The 17th was mainly sunny for most but it clouded over in the north-west with patchy rain and drizzle. A warm humid weather pattern then set

showers by the time it reaches northern Wales and northern England later in the afternoon. Blustery showers will follow into northern Scotland, where it will remain windy throughout the day. Elsewhere, conditions will be predominantly dry with sunny spells and variable cloud cover. There is a slight
in the north and west, and very gusty conditions over high ground. After a mild night, Sunday will feel warm and humid in brighter spells, especially in East Anglia and south-east England, where temperatures are likely to reach the low to mid 20°Cs. Cloud amounts will limit higher temperatures
Most areas will enjoy a fine and dry day with sunny spells. Early cloud across parts of northern England, the north Midlands, and Lincolnshire will gradually thin and break, allowing sunshine to develop. Any early showers or rain in these areas will ease. Isolated afternoon showers are possible
into Monday night, cloud and more organised showers or rain will affect central, western, and southern Scotland, as well as northern England. Elsewhere, showers will become increasingly focused towards western coasts, while winds slowly begin to ease. Temperatures will be at or slightly above average
challenging to predict exact solar radiation levels, particularly in longer range forecasts, because of the influence of clouds at local level. We all know how changeable Britain’s weather can be. Cloud cover can vary even over a distance of a few miles and on timescales of a few minutes. For example
