Early mist and fog tomorrow will soon lift to leave a dry and bright day for most areas, but it will be cloudy in northern Scotland. MeteoGroup forecaster Paul Mott said that after snow fell on the Pennines today, the weather will be 'quite a bit different' for the next few days. ‘It will certainly turn much warmer,’ he said. ‘Across England and Wales it will be dry, bright and there will be lengthy periods of sunshine.’ Temperatures will reach as high as 16C (61F) in south-east England tomorrow, while Scotland will be cooler, with the mercury as low as 10C (50F).

Mr Mott said the forecast for Thursday and Friday was ‘more uncertain’ when it is expected to be cooler but will remain dry. The predicted hot weather is result of a plume of warm air heading towards the UK from the south west, coming from as far as the Azores Islands.

Additionally, with summer seeming to come early for many last week, doctors reported seeing hay-fever sufferers experiencing symptoms. This was despite the pollen levels being moderate for much of the south of England and low for the rest of the UK according to the Met Office. The Sunday Telegraph warned today of a 33 per cent increase in the number of people facing hayfever this year because of worsening conditions. High pollen counts are mixing with heavy pollution and Saharan dust, with hayfever now twice as common in towns and cities than the countryside.
