A lot of chat going on about some fine weather coming to the UK, a spell of heat and summer sunshine. Bound to get the British public a bit excited, some straight out in their shorts but for others it brings health concerns.
So this spell of fine settled weather is thanks to an area of High pressure, which continues to sit over the UK for several days, allowing day time temperatures to rise. All the forecast models agree on this. The High will still be here for next weekend (13th) but will a little less hot blip in the middle
The highest temperature ever in the UK was in August 2003 in Kent at 38.5 (101F).Temperatures like that need a longer build up of heat, stored up in the ground .
By the start of next week (15th), the high begins to drift back west into the Atlantic and so temperatures will subside as the airflow changes. St. Swithin's Day, the day that supposedly marks the start of 40 days of sun or rain.
At the northern edge of the high, showers will still sneak in for the Western and Northern isles from time to time, but even so there will still be some fine weather here too. Inland across the UK, there will be the risk of an isolated heavy shower, set off by the heat, but mianly it's a lot of sunshine, heat and dry weather.
Temperatures widely into the mid 20'S Celsius, nudging 30C in southern England. There is a brief blip for eastern Britain and central England on Weds/Thurs as a cold front sinks down from the north. Temperatures down to 21C but they recover by Friday once more.
However, sitting outside in the sun all weekend could just give you a headache, or for some people more serious health worries. The NHS do have a warning system in place in conjunction with the UK Met. Office. An average temperature of 30°C by day and 15°C overnight would trigger a health alert (this figure varies slightly around the UK). These temperatures can have a significant effect on people's health if they last for at least two days and the night in between. It is worth remembering that even on a cloudy day, you can still get sunburnt.
Heatwave Health Information From the NHSSouthwestern parts of the US have been seeing day to day temperatures over 100F, so similar to our UK record. This weather set up is an isolated inland high, stagnating and allowing temperatures to rise and dry air to stay in the same place. The High for the UK, comes from the Azores in the Atlantic.
