It will feel notably cooler through the coming days as temperatures fall and easterly winds pick up.

Winds will ease toward the end of the forecast period and conditions will brighten again before the end of the weekend.

Wednesday 21/11/18
On Wednesday we have a large, but weak, area of low pressure over the western Bay of Biscay while a weak ridge of high pressure extends from Norway across the North Sea. This maintains a northeast to easterly flow for much of the British Isles so it will be another cold day. There will be extensive cloud, with outbreaks of rain, particularly in the east. Far western areas tending to be brighter with sunny spells developing here. Highs of 6 to 9C, though feeling colder in the fresh to strong winds.

Thursday 22/11/18
An area of low pressure remains over the Bay of Biscay on Thursday while a ridge of high pressure extends east-west to the north of Scotland. This mains the easterly flow for much of the country. It will remain cloudy but it will be drier than Wednesday with rain staying rather confined to eastern Scotland, northeastern and southwestern England and Northern Ireland. The best of the brighter weather will be in the far west of the British Isles. High temperatures will reach 6 to 8C across the country though parts of the south could see 10 or 11C.

Friday 23/11/18
The weak low remains over the Bay of Biscay while the high pressure to the north shifts its centre over Iceland. This introduces a southerly airflow for southern parts of Ireland and England which will make temperatures feel milder. A cold easterly flow will persist for the northern half of the country. It will be a cloudy day with outbreaks of rain for Wales, western England and eastern Scotland. Best of the brightness in the northwest of Scotland and northwest of England. Highs of 6 to 11C.

Saturday 24/11/18
A very similar day to Friday with not much change to the synoptic set-up or weather conditions expected. Another cloudy day with outbreaks of rain for Wales, southern and western England, eastern Scotland and northeast England. Highs of 7 to 11C.

Sunday 25/11/18
High pressure strengthens to the north of the country as it centres over Greenland reestablishing the easterly airflow for the British Isles. It will be another cloudy day for most though rain will become confined to eastern coasts. Sunny spells will develop by the afternoon for much of England. Highs of 4 to 10C.

Monday 26/11/18
The easterly flow is maintained for the British Isles as low pressure moves inland from the Bay of Biscay into Europe and a high pressure ridge extends from Greenland to Norway. It will be a cloudy day around western coasts and in the southeast with rain for eastern coasts and Northern Ireland. Highs of 4 to 9C.
