Thursday was the first above average maximum in two weeks. The thermometer rose to a maximum of 15.9C at 14.39 being 1.1C above my 40-year average. The peak occurred early afternoon, this was due to variable cloud drifting across on the easterly breeze after midday and just before 15.00 much larger clouds obscured the sun for much longer periods. Once again the clouds dispersed over night so no duvet to minimise the loss of warmth into the atmosphere that resulted in the thermometer dropping away to 2.3C at 05.24.
The recent rainfall and low minimum temperature caused radiation fog to form that limited visibility to 200mm at its worst but by 07.45 there were early signs that it was beginning to thin as the sun rose above the horizon and began to brighten. The humidity at 08.00 read 99% that meant little rise in the temperature since the minimum with a reading of 3.7C at 08.00.
The anticyclone is still centred in the NorthSea but there is a slight change in its coverage, which is producing the airstream to change from east on Thursday to south for much of today. The barometric pressure has been constant since yesterday with a reading at 08.00 of 1021.9mb.
