Friday was relatively calm and still warm but 4C down on the high peak of Thursday reaching 11.3C at 11.15, however, this was still 3.2C above my 40-year average. Before the cloud built up in the early hours of Saturday ahead of the next weather front the thermometer dropped to 6.9C at 01.10, which was 5.3C above my 40-year average.
The UV level of 1.5 on Friday was the highest since 25th October so the light is getting stronger though still rated as ‘Low”.
Saturday dawned with very low cloud that totally covered the trees in Savernake Forest and draped over the top of the Marlborough Downs. This is thanks to two warm fronts crossing southern England today on a light southwesterly air stream that will bring much rain later in the day. The anticyclone that produced a ridge of high pressure yesterday is still in position, reading of 1028.7mb at 08.00, the highest since the 3rd, but will slowly decline today as a depression arrives from the Atlantic tomorrow. Overnight and into Sunday two cold fronts will cross our area bringing sightly cooler air.
