    Meteorological autumn started just a couple of days ago on the 1st September and so far the season has brought fairly unsettled and cool weather to the United Kingdom. Don’t worry if you don’t like the way the autumn is developing though, because a change is on the way and we should soon being seeing a spell of more settled weather.

    The first two days of September have seen showers and more persistent rain affecting the UK and there has been some heavy rain in some places. Dundrennan in Dumfries and Galloway received 21mm of rain on the 1st of the month. The second day of the month was no better with further heavy showers affecting many areas. Merseyside and north-east Wales were worst affected – 40mm of rain fell in the range gauge at Hawarden in Flintshire - and there were reports of flooding.

    It has also been quite a windy few days with northern and particularly north-eastern parts of the UK bearing the weight of the wind. Gusts of 30-40mph have been recorded in parts of northern Scotland in the last couple of days and, whilst not unusually strong, the wind has helped to make it feel rather cool for the time of year.

    A lot of the unsettled weather has been due to a low pressure system which is currently sat to the east to the United Kingdom over the North Sea. This low pressure system will move away and a large area of high pressure which is currently situated over the northwest Atlantic Ocean will take up residence during the weekend. As a result most parts of the country will have mainly dry, settled weather with light winds by the start of next week. The north to north-westerly winds we’ve seen in recent days will have gone so and temperatures will recover to nearer normal for the time of year. However, some cool nights are likely and there may also be some early mist and fog.

    How long the settled spell of weather will last is a little uncertain. There are some signs of more unsettled weather pushing in from the Atlantic during the second half of next week, but this is by no means certain and we may see reasonably pleasant weather in some places right through next week.
