The much cooler air stream on Thursday brought on the northerly breeze saw the thermometer struggle to reach a high of 11.7C at 14.39 before beginning to drop back. This maximum was 3.2C below my 40-year average and the coolest day since 27th April. There was a brief shower of light rain and drizzle, starting just before 10.00, that produced 0.2mm of precipitation. The temperature levelled out at a temperature of around 5C until after 03.00 early Friday before clearing skies saw it steadily drop to a minimum of -0.4C at 07.36, being a significant 7.4C below my 40-year average. The thermometer dropped below freezing just after 07.00 and produced not only a ground frost but the frost air frost of the season.
Friday gave us a clear sky and sunshine after sunrise that began to lift the temperature very slowly reaching -0.2C by 08.00. The wind direction has changed from north to come from the southeast for the bulk of the day.
The high pressure system, reaching from mid-Atlantic to Germany, will be around for a couple of days so there will be a few cooler days being mainly dry with variable sunshine.
