Wednesday 19th November
There was a slight recovery in the daytime maximum on Tuesday as the wind came from the southwest to start the day and then veered back into the northwest as the afternoon and evening progressed. As a result the high of 8.0C was logged at 13.42, being 2.3C below average.
The temperature hovered just below 5C for much of the night, giving us a relatively mild night. However, just after 05.00 the temperature record showed a slow fall to 3.3C at 07.00 then dropped further to 1.9C at 07.48 as the wind built up, gusting to 19mph. At that time the wind chill was significant so that outside it felt more like -0.2C.
There was a significant weather feature at 07.48 when a brief sleet shower was observed in the strong northerly breeze at the lowest temperature all night.
Wednesday arrived with total, thick cloud cover that was low once again producing misty conditions that draped the Marlborough Downs. A fragmented weather front, associated with the departed depression, has been crossing the area since the early hours that has produced sporadic rainfall amounting to 2.0mm.
The low-pressure has eased away eastwards over the North Sea with its air mass circulating anticlockwise, whilst a high pressure system with a clockwise wind pattern in the Atlantic accentuates the wind strength, resulting in a a squeeze in the north wind bringing Arctic air down across the UK.
The Jet Stream would indicate that the high pressure will edge closer on Friday, sending a ridge across the UK, which will quieten things down and bring a slight recovery in the temperature.
Update at 08.45. First light snow of the season observed at 08.45 from the back edge of the weather front as the thermometer dipped to 1.6C.
