Monday gave us some brief sunshine in the early morning, before the cold front brought thick cloud and obscured the sun, amounting to just 10 minutes. The influence of the initially westerly breeze and lack of sunshine meant a day with below average temperatures with a maximum of just 12.9C at 13.47 (1C below average). Just after 5pm the cloud thickened, the wind veered into the north and the thermometer began to fall steadily in the cooler air. This made yesterday the wettest day this month with just 1.1mm, bringing the total for April to 2.1mm making it the second driest April since my records began in 1984. Yesterday is classed as a wet day, which meteorologically is any twenty-four hour period with precipitation equal to or exceeding 1mm.
To sum up yesterday: lowest night temperature, lowest solar, lowest evaporation, strongest wind gust and wettest day.
There was an air frost for a couple of hours starting just after 3am this morning, giving a minimum of -0.7C. There was little evidence of this due to the very dry air, 81% humidity at 08.00.
