Sunday was another cool, cloudy day, however, the peak temperature of 10.8C was just above average (+0.7C) thanks to the very gentle southwesterly air stream.
Overnight, but especially in the early hors of Monday, the temperature fell away, dropping to 4.8C at dawn, also above average (+1.1C).
Monday dawned with a little brightness at first but the wind is going to change and veer into the Northwest then North as the day progresses. This is a forerunner of a significant change in our weather pattern as high pressure will come to dominate to the east of the UK bringing a much cooler airstream from the east or southeast as we move into Tuesday.
