Another mainly dull day again on Tuesday with bursts of late afternoon and evening sunshine that lifted the thermometer to a maximum of 23.5C late in the day at 18.53. This peak was 0.8C above my 40-year average. However, it was a dry day although the sunshine late in the day meant the UV level only peaked at High.
It was the coolest night for over a week that saw the thermometer drop to 10.6C at 05.53 being 1.6C below average. This lower temperature, combined with low cloud and still conditions, meant that fog formed after dawn that initially just masked the Marlborough Downs and Savernake Forest. However, just before 07.00 the fog slowly thickened limiting visibility to 200m by 07.10. After 07.30, as the sun began to strengthen, the fog very slowly began to disperse.
The brief ridge of high pressure will give us a fine day, so enjoy it, but will slowly edge away as the day progresses due to a depression over Iceland approaching the UK. Associated weather fronts will bring variable rain amounts tomorrow.
