Cold and breezy
Wet on Wednesday

Monday
A large area of high pressure centred over Scandinavia extends a ridge across the British Isles on Monday bringing cold east to southeasterly winds which will be moderate to fresh in eastern and southern areas. It will be cloudy a cloudy day across Ireland, southern Scotland, Wales and much of England with increasing sunny spells further west. The best of the brightness will be in the Western Isles. There will be some outbreaks of rain and drizzle developing in the afternoon for Fife and the southeast of England. Temperatures at 5 to 9C.


Monday Night
Monday night will see cloud continuing to push over Scotland and England from the North Sea coast bringing prolonged periods of light rain and drizzle extending westward as far as Wales by morning. Winds will remain moderate to fresh. Overnight lows of 0 to 3C over higher ground, more typically 5 to 8C at lower levels but feeling cold in the moderate to fresh winds.
 


Tuesday
High pressure over the Norwegian Sea and low pressure over southwestern Europe keep the British Isles sandwiched in an easterly airflow on Tuesday. It will be a cloudy day for most with only the western fringes of Ireland and Scotland seeing any real brightness. Rain and drizzle will continue to affect eastern areas though a plume will stream across the Midlands bringing some wet weather as far as Wales. Cold again with highs at 4 to 8C.


Wednesday
A large, but weak, low pressure area over the Bay of Biscay will begin to exert a bit of an influence over the southwestern part of the country on Wednesday. High pressure remains off to the north keeping the northern part of the country in that cold easterly airflow however southwestern areas will have a bit of respite from the cold as the wind is blowing from the south. It will be a cloudy, wet day for most with the best chance of any sunny spells developing in the southeast. High temperatures could reach 9 or 10C in the southwest, 4 to 7C more likely everywhere else.
