Sunshine and later brightness Monday morning lifted the temperature to a peak of 9.4C but the southeasterly breeze meant this was depressed and 1.2C below my 40-year average. Cloud slowly built up after midday with thickening cloud that brought rain starting at 15.50, which eventually amounted to 2.3mm in total. The cloud cover minimised loss of warmth into the atmosphere overnight acting as a duvet so the minimum of 4.6C at 06.36 on Tuesday was 2.1C abject my 40-year average so no frost, air or ground.
First light on Tuesday revealed another foggy start to a new day with visibility reduced to 200m initially but by 07.30 that had increased to 300m and by 08.00 had thinned considerably so that distant features could be observed at 500m.
A high pressure over Scandinavia is termed a blocking high as it is resting the forward movement of depressions trying to move in from the Atlantic. In fact the low pressure area from yesterday, recently over the West Country, is slowly filling this morning.
