Last night turned out as cold as we predicted with the minimum overnight temperature reaching 6.7c at midnight. With Autumn only a few days away (22 September) yesterday was a taster of what is in store.
Today will be a much milder affair due to the jet stream position. Currently the jet stream is running down the UK from N to S, however, as the day passes it will take a more W to E path.
For the morning we will see some bright spells through thin or fragmented cloud. This will help lift our top temperature up to around 18c. As the day passes the cloud cover will increase and by mid evening our area will be under a general covering of cloud. This cloud will help maintain the residual heat and our overnight minimum temperature will be around 11c.
Despite the increase in cloud we should remain dry all day. We will, however, notice an increase in wind speed as the day passes. This is due to the pressure systems formed by the movement of the jet stream. During the afternoon and early evening we can expect wind speeds of around 10mph and gusts of 25mph. The surface wind direction will be from the WSW-SW.
Dry and bright start – clouding over later.
