UK Faces Unseasonably Cold and Wet Start to Summer

June brings cooler temperatures and frequent thunderstorms as the jet stream pulls Arctic air over the British Isles.

Temperatures in early June are significantly below average, contrasting with last year's heatwave.
The jet stream's southern loop has exposed the UK to colder northern air, causing unsettled weather.
Frequent thunderstorms and heavy showers are predicted to continue into the weekend.
Meteorologists suggest that warmer weather may arrive later in July and August, though predictions are uncertain.
Climate change and El Niño contribute to the increased rainfall and cooler temperatures.
