What weather conditions are typically associated with areas of high and low pressure?
Thunderstorms develop when the atmosphere is unstable - this is when warm air exists underneath much colder air. As the warm air rises it cools and condenses forming small droplets of water.
Take care when travelling in heavy rain, wind and thunderstorms.
Please note that when changing units, only forecasts and maps will be affected.
