The jet stream over the UK is currently positioned at 52°N, with core wind speeds of 140–160 mph at 250 hPa, driving a series of Atlantic low-pressure systems. This means unsettled, wet and windy conditions are likely for most of the week, with the strongest winds across northern Scotland.
What is the jet stream forecast for the next 7 to 14 days?
The 7 day jet stream forecast uk shows a persistent south-westerly flow, with the core remaining south of Iceland and crossing northern Britain. By day 5–7, a trough amplification may push the jet further south, increasing the risk of heavy rain for southern England. The 10 day jet stream forecast uk indicates a gradual weakening of the jet by day 10, allowing high pressure to build from the Azores, bringing drier and more settled conditions for the following weekend.
How does the 30 day jet stream forecast look?
The 30 day jet stream forecast suggests a transition to a more meridional pattern, with the jet stream dipping south over the eastern Atlantic around week three. This could bring a colder spell with a higher chance of frost and wintry showers, particularly for northern and eastern areas. The 7 day jet stream forecast map from the Met Office shows the strongest winds shifting north-eastwards by day 7.
What does a strong jet stream mean for UK weather?
A strong jet stream acts as a conveyor belt for low-pressure systems, bringing wind and rain. When it sits over or just north of the UK, expect frequent Atlantic storms and milder temperatures.
Where can I see a 7 day jet stream forecast map?
The Met Office provides a 7 day jet stream forecast map on its website, showing wind speed and direction at 250 hPa. It is updated twice daily and is useful for tracking storm tracks.
Will the jet stream cause any weather warnings this week?
Yes, the strong jet stream is likely to trigger Moderate Rainfall Warnings for western Scotland and north-west England, with gusts potentially reaching 60 mph on exposed coasts.
