I am indebted to my lifelong friend in Australia who voluntarily burnt the midnight oil in updating the website yesterday with a new template and added the ‘live’ feed from my latest professional weather station. There are a few more tweaks before it is fully operational, including an image, which has mysteriously disappeared!
Wednesday brought variable light cloud that saw the thermometer reluctant to rise until after 09.30 but later in the brightness saw the temperature pick up to a maximum of 8.9C at 13.18, being 0.5C above average, before thicker cloud drifted across after 14.00. There was little air movement under the high pressure with a maximum movement of just 7mph on one occasion with the anemometer stationary for long periods.
The barometric pressure has been building for the past twenty-four hours, tailing off in the early hours, as the intense anticyclone edged from the west over central England with its centre approximately 40 miles north of Marlborough. The pressure increased 8mb since yesterday to give a very high pressure reading of 1043.7mb at 08.00, being the highest pressure here since 6th February 2023.
The temperature slowly ebbed away during the evening to reach a minimum -1.2C at 02.04 early Thursday that was 3.1C below the long-term average and produced an air frost.
Thursday brought a glorious start to the new day with weak sunshine through thin high cloud but gained in strength as it rose higher. The high pressure will mean another calm day but the significant change is in the wind direction, which has veered from the northwest yesterday into northeast today that heralds the arrival of much cooler conditions.
This expanding high pressure system will dominate our weather for the next few days with a cool northeasterly or easterly breeze that will see temperatures by day and night depressed.
