14 day UK weather forecast

Warm start but turning cool and showery.

UK outlook issued Sunday 19th August 2018

Week 1

Warm start but then cooler and changeable.

Monday: Scattered showers are likely but many places have a dry day with sunny spells. It will be warm with temperatures in southern and central regions peaking at close to 26C (78F).

Tuesday: England and Wales have a mostly bright and warm day. In Scotland and Northern Ireland cloud thickens and outbreaks of rain push in from the west.

Wednesday: A band of wet weather in the north steadily pushes southeastwards and is followed by clearer and cooler conditions. The rain is expected to reach central counties by the evening but to the south of it warm sunny periods develop, and temperatures could reach 28C (82F) in East Anglia and south eastern England.

Thursday, Friday, Saturday, Sunday: Changeable. The driest spells are likely to be in the south west but even there, there is a risk of showers or longer spells of rain. Temperatures will probably be below the seasonal average for much of the time.

Forecast confidence is high falling to moderate later on.

 



 

Week 2

North to south split.

Northern and western regions have changeable conditions with a risk of showers or longer spells of rain, but also drier and sunnier days. Southern and eastern counties could see showery rain at times but there should be a good deal of dry weather. After a cool start temperatures recover and in the south it may become warm.

Forecast confidence is low to moderate.

Overview

Week 1

Warm air filters northwards early on but through the middle of the week weather fronts move southeastwards and a cooler northwesterly air stream becomes established. Towards the end of the period high pressure centred over the Azores may push northeastwards towards the UK again.

Week 2

High pressure is expected to remain close to the south of the UK for much of the week. In the north an Atlantic flow persists and disturbances in it keep things quite unsettled.

Points of note

After a warm start it turns cooler and showery in all regions. The mixed weather may well last through the Bank Holiday period.
