  . As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. Consequently, the weather in a depression is often cloudy, wet and windy (with winds blowing in an anticlockwise direction around the depression). There are usually frontal systems associated with depressions. Figure

• Met Office daily weather: Largely fine and warm weekend

  While some areas will start off cloudy, particularly in the east, conditions are expected to improve as the days progress, offering ideal weather for outdoor events and activities. Saturday will begin with widespread cloud cover across Scotland, England, and eastern Wales, accompanied by hill fog

• Met Office daily weather: Widely sunny spells to end the week

  temperatures are expected to reach between 27°C and 29°C quite widely, with some locations in southern England potentially peaking at 30°C or 31°C. Further north, conditions will remain largely dry and warm, although there will be more cloud, particularly along North Sea coasts. A few isolated showers

• Met Office daily weather: Warmth and sunshine midweek

  Tuesday begins on a cloudy note across central and southern Britain, with occasional rain and drizzle. However, conditions are expected to improve as the day progresses, with the cloud clearing from the north and rain becoming confined to southern counties. Inland areas will see the low cloud
