The jet stream is a narrow band of predominantly westerly winds found 9-16kn about the Earth's surface which has a big impact on the UK's weather.
During the winter months when the jet stream is strong and close to the UK we can expect stormy conditions as it directs areas of low pressure in our direction. Colder spells usually occur when it is weaker and to our south.
As well as these the TWO chart viewer provides a huge range of charts from many different computer models.
