Met Éireann explained that the warm weather is due to a "displaced" jet stream to the far north of Ireland, "drawing in warm air and allowing high pressure to 'get stuck.'"
Why is it so warm & sunny? ?
The jet stream has been displaced to the far north of Ireland, drawing in warm air & allowing high pressure to "get stuck" bringing us this settled and sunny weather.
Temperatures today could reach 30°C or higher in a few places ??️
