Summer is finally here, and it seems temperatures are set to stay warm and sunny this weekend. 

The weather forecast for Saturday (June 29) and Sunday are set to be sunny intervals changing to cloudy by lunchtime.

Elsewhere, the weather will be fine with variable cloud and sunny spells, feeling warmer in the south and cooler in the north.

The weekend will see plenty of warm and dry weather, especially in the south and east. There will be some cloud and patchy rain or showers around, mostly across central and northern parts of the UK where it will be on the cool side. Southern parts will often see dry and bright weather where it will feel warm in the sunshine.

Saturday's forecast is 'sunny intervals changing to cloudy by lunchtime.' Highs of 20C. Lows of 13. Bad news for hay-fever sufferers though with pollen levels remaining high.

Sunday (June 30) starts off cloudy but changes to sunny intervals by late morning. Highs of 21C. High levels of ultra violet light (UV) but still very high pollen levels.

On Tuesday, the UK Health and Security Agency issued a yellow weather alert for the heat, which they say that minor impacts are probable across the health and social care sector - these include:

"Increased use of healthcare services by the vulnerable population."

"Increase in risk of mortality amongst vulnerable individuals and increased potential for indoor environments to become very warm."

A spokesperson for the Met Office explained: "Yellow alerts may be issued during periods of heat which would be unlikely to impact most people, but those you are particularly vulnerable (E.g. the elderly with multiple health conditions and on multiple medications) and are likely to struggle to cope and where action is required within the health and social care sector specifically.

"A yellow alert may also be issued if the confidence in the weather forecast is low, but there could be more significant impacts if the worst-case scenario is realised.

"In this situation, the alert may be upgraded as the confidence in both the weather forecast and the likelihood of observing those impacts improves."
