Monday was a very warm day that saw the thermometer climb to 18.4C being 3.9C above the average and the second warmest day in October.
Overnight was the opposite as under clear skies the temperature dropped to 3.3C at 08.02 on Tuesday. This low temperature was 3.9C below the 38-year average and caused fog to form in the early hours as the moisture from the previous day’s rain condensed.
Tuesday at first light brought variable fog and mist that varied from 400 metres to 800 metres. However, as sunrise approached the fog thickened to limit visibility to 200m. The barometric pressure has risen so we are currently under a ridge of high pressure with a reading of 1027.8mb at 08.00, a rise of 15mb since this time on Monday.
