Rain, drizzle and ground frost all in twenty four hours

After another dreary day with intermittent drizzle and light rain, totalling 1.3mm, late afternoon the sky began to lighten. As a result, the temperature dropped from a high of 9.2C, which is 2.3C above the mean, to a minimum of 1.9 very early this morning at 01.01 briefly giving a light ground frost. Since then the thermometer has recovered to 5.2C at 08.00.
Yesterday was the windiest day for over two weeks, after the recent very still conditions under the intense high pressure, with a maximum gust of 27mph just after 2pm. The barometric pressure was at its lowest just after midnight, at 1009.9mb, and is now rising. As a result the wind has veered into the west giving a brighter morning, if short lived, with much lower humidity, currently 92% after 99% for several mornings at 08.00.
