Sunday 28th June
Although the maximum on Saturday of 29.2C it was down 3C on the Friday peak also 5C down on the Thursday peak. The high was 8.4C above my long-term average and still above the heatwave threshold of 27C. Although the UV strength has been High this past week, yesterday it rose at its peak to Very High. The minimum of 16.6C at 02.51 early on Sunday meant another very warm night but thankfully, not a Tropical night, being just 6.4C above average.
I noted the heat index yesterday at 14.30 was significant, as it has been all week, with a radiation shielded thermometer indicating the air temperature was 29.0C whist outside on a person it felt more like 37.6C.
Sunday arrived with variable sunshine through breaks in the cloud that had lifted the temperature to 19.8C by 08.00. A significant feature in our weather today will be the passage of two weather fronts, both cold fronts, that will usher in behind them a cooler air stream that will result in the breeze backing from southwest this morning to west this afternoon and tomorrow. The result will be maxima and minima over the next few days likely to be just above average for late June.
The advancing low pressure system is now centred between Scotland and Iceland that has brought the change in our weather pattern and associated weather fronts. A series on low pressure systems are shown on the forecast pressure charts arriving over the next few days continuing the pattern of sunshine between variable cloud although the Azores High is all the time just to the southwest that will mean minimal risk of organised rainfall.

Over the last two months the UK has experienced two heatwaves, which have shattered significant, long-standing temperature records.
This hasn’t happened since 1911.
And we’re still relatively early in the summer with our hottest weather normally coming in late July and into August.
While the current June heatwave will gradually come to an end over the weekend, with a return to more average conditions next week, there are already indications that we could see more heatwaves this summer.
It has been a bit of a weather rollercoaster since May when a large area of high pressure – known as a ‘heat dome – sat across the UK bringing dry, sunny and very warm weather. A new May record temperature of 35.1C was set in Kew Gardens, London.
