Thanks to the brisk northeasterly the thermometer struggled to each 3.7C on Sunday, some 3.4C below my 40-year average. The wind was brisk so that it felt outside some 2C blow that indicated on an outside thermometer classed as wind chill. The overnight minimum of -0.2C occurred at 03.40 Monday so there was briefly a ground frost. By 08.00 Monday, the thermometer had eased upwards, above freezing, to 1.1C.
Monday initially saw much clear sky but by 07.30 a large, thick bank of cloud could be seen to the northeast that by 08.00 had almost completely covered the sky. It was the coldest start to a day for a month. The airstream from the northeast is much drier, a humidity reading at 08.00 logged 79% making it the lowest humidity at that tine since 26th June (70%). The barometric pressure at 08.00 was 1033.6mb, the highest since 16th December (1040.8mb).
The anticyclone centre has edged eastwards so that the anticlockwise rotation of air continues to come from the northeast.
