The wind from the north-northeast and northeast on Friday depressed the temperature and produced a wind chill. The maximum of 14.6C was 2.5C below average and outside in the strong breeze, gusting to 27mph, meant it felt at least 1C lower.
The thick cloud arrived overnight from the North Sea on the northeasterly wind, as a result the minimum of 8.0C was 1.2C above the average.
Saturday revealed the thick and total cloud cover that had rolled in from the NorthSea. The temperature at 08.00 was 8.4C, the coolest start to a day at that time since the 2nd (8.2C). The soil temperature at a depth of 5cm was 10.7C at 08.00, the lowest since the 4th (9.9C). The wind continues from the northeasterly direction due to the anticyclone still over the country with a ridge of high pressure with its centre over Northumbria. The wind circling in an anticlockwise direction means the air has traveled over the North Sea, which is cold at this time of year and also picks up moisture, hence the thick cloud cover.
