Met Office forecaster Alex Deakin said: “Looking at the bigger picture, high pressure is to the North, low pressure to the South West.

That battle between the two fronts will also create some windy conditions as well.
Mr Deakin added: “As the low squeezes up against the high, the isobars push together, suggesting at times it’s going to be quite blustery”.
A blustery easterly wind will give a chilly feel for some on Wednesday.

Speaking about Friday, Mr Deakin said: “There will be showers coming and going through the day.
