UK WEATHER FORECAST 8/11/2018

Another low pressure system is moving close to the UK, though it will move towards Iceland bringing tropical maritime air towards the UK. Possible showers are expected during the day in Northern Ireland, Irish Channel and Western Scotland due to an occluded front stationary between Ireland and Scotland, and some showers could be possibe during the night of the east of England due to the presence of a trough.

During the night some showers are possible on Eastern England, and moderate rainfall is expected on Wales, Irish Channel, south-western England. During the morning rainfall is expected moving on Western Scotland, Northern England and Northern Ireland. Instead during the afternoon and evening possible showers still expected on Western Scotland instead brighter skies are expected on the east (afternoon) and in Cornwall (evening).

The temperatures, due to overcast condition and southerly winds will significantly increase everywhere (8-14 °C), and the maximum will be similar (8-15°C). However, from the evening cooler air moving from the Atlantic and clearer skies would cause a decrease in temperature in Northern Ireland, Wales and Western Scotland (5-10 °C) , instead still milder conditions on the east (10-13°C).

The winds will be southerly most of the day, turning westerly/south westerly during the afternoon. They will be moderate on the English Channel (most of the day), Irish Channel (morning) and Eastern England/Scotland (day).

In the rest of the country settled conditions with bright sky especially in the west (Wales, Cornwall), though from the evening some showers are possible in Northern Ireland and Western Scotland due to an occluded front moving eastward.

Due to cloudier sky, minimum temperatures will see an increase, with values mostly between (2-8 °C, highest values on the east coast) and only in Wales, Scotland it could be reach (-1,-2 °C).
