Wednesday produced the fifth consecutive below average maximum with a peak of just 11.2C at 15.15 being 2.9C below the average. At least it was a dry day although the variable cloud meant the UV level was only ‘Moderate’.
The temperature slowly fell away in the evening that by 23.00 registered 1.7C and then no surprise to find it dipped below freezing for almost three hours with a minimum of -0.7C at 02.23 producing not only a ground frost but an air frost, only the second this month.
After the sun had risen above the cloud bank on the eastern horizon on Thursday it began to shine strongly just after 07.30 lifting the temperature to 5.9C at 08.00. However, shortly after 08.15 advancing cloud began to mask the sun. The wind has backed into the west overnight and will continue from that direction until late evening when it will come from the northeast or north-northeast.
Today we will be under a ‘trough’, which forms as the jet stream dips down and forms a bowl shape in the pressure gradient. It will result in cooler weather and rain that is likely around midday or shortly afterwards and likely to become heavy during the afternoon. The barometric pressure has fallen further, with a reading of 1007.0mb at 08.00,a drop of 24mb since its peak on Sunday. The wind fell light overnight, assisting the drop in temperature and is likely to remain light for much of the day.
