Very warm but risk of thunderstorms increasing

[Updated 07:10 18/06/2013]

The weather will continue to warm up during Tuesday possibly making it the warmest day of the year so far. Very warm air is pushing up from south, but it will be increasingly humid with a fair amount of cloud at times too. Through the afternoon heavy showers or thunderstorms are likely to start breaking out in the south, but many places should stay dry. In northern Britain there will also be sunny spells, although it wont be as warm, and in Scotland there is likely to be a lot of cloud. Tomorrow will be even warmer and temperatures in the south should reach between 27C (81F) and 30C (86F) depending on the amount of cloud cover. The second half of the week will see the warmth returning east to the continent with cooler air from the Atlantic returning to Britain. The weekend weather isn't looking great at the moment with low pressure possibly sitting over Britain bringing heavy showers or longer spells of rain. Glastonbury and the Wimbledon tennis tournament are rapidly approaching and Buzz will keep a close eye on the unfolding weather.
