There was a significant change in the airstream on Friday as the high pressure to the southwest cut off the cold Arctic air stream and brought a slightly warmer air on a very light westerly, with a maximum movement, couldn’t call it a gust, of just 9mph. The temperature slowly rose to a maximum of 16.9C at 14.48, up 3C on the low of Thursday but still 2.2C below my 40-year average. It was a dry day with the UV level at the top end of ‘Moderate’.
Saturday began with muted sunshine but soon the sun rose above the thin cloud on the eastern horizon and began to shine strongly lifting the temperature to 6.4C at 08.00 after the minimum of 3.3C occurred 06.51, up 2C on the Friday low, but still a significant 5.4C below my 40-year average.
The centre of the high pressure is over the English Channel and is likely to give us a few days of warmer, sunnier and dry weather. The barometric pressure has risen another 2mb to read 1031.5mb at 08.00. As the anticyclone relocates the air will come predominantly from the southwest today.
