A Cold Easterly

After a few nice days at the beginning of the month the weather has now reverted into winter mode rather than meteorological spring. Those westerly winds that blow in off the Atlantic do give us some changeable weather whereas with high pressure in charge and easterly winds blowing in off the North Sea we get settled conditions. It’s just that the settled conditions aren’t at all good.
The above chart is a bit messy. The purple shading clearly shows how the wind direction has moved out of the west and into the east. The yellow blocks show the amount of solar energy received each day and the considerable reduction over the last few days as a result of very cloudy conditions. The temperature hasn't fluctuated much either with no particularly cold nights but no mild days either.
