Rain, strong wind, ground frost, valley fog, it must be Winter!

After a relatively dry start yesterday, with just dampness in the air, rain set in just before 11am. Rain continued until around 8pm, with very heavy falls between 6 and 7.30pm, totalling 8.5mm. There were strong gusts of wind later in the day with a maximum gust of 25mph at 19.15. It was at this time that the cold front left the area, the barometric pressure began to rise rapidly and the wind to abruptly veer from the south into the north-west. The thermometer then began to drop consistently from a high of 12.1C at its maximum to 7C at 19.30 and a minimum of 2.8C at 05.05. This low temperature gave a ground frost and caused fog to form in the River Og valley outside Marlborough.
This morning there is hazy sunshine as a temporary ridge of high pressure gives respite from the thick cloud and rain.
