14 day UK weather

Cooler and changeable. Very wet at times.

UK outlook issued Thursday 22nd June 2017

Week 1

Increasingly changeable.

Friday: Outbreaks of rain in the north push southeastwards but become lighter and patchy. Drier and brighter conditions return to the north. Southern counties remain dry but after a bright start cloud is likely to build from the north during the afternoon.

Saturday: Southern and central regions have showers which could merge to give longer periods of rain at times, but there should be brighter spells too. The north has a mix of sunshine and showers. Cool in the north but still reasonably warm in the south in any sunshine. Windy, especially in the north where gales are possible in exposed locations.

Sunday: Showers continue in the north. Southern and central regions have dry and bright weather but cloud may build in the west during the second half of the day. Quite warm in the south but cool in the north.

Monday, Tuesday, Wednesday, Thursday: All regions have showers or longer periods of rain. Drier spells are most likely in the south east but even there wet weather is expected at times. Rather cool in the north but in the south temperatures should be close to the seasonal average.

 

Forecast confidence is moderately high.

 

 

Week 2

Changeable but perhaps becoming drier and warmer in the south.

Mixed weather is expected with a risk of showery rain, but in the south a transition to drier conditions could develop. Temperatures are likely to be close to average in the north west, but southern and eastern areas may become warm.

Forecast confidence is moderate.

Overview

Through the first week an upper level trough across the North Atlantic and areas of low pressure dominate the weather across the UK. Their influence will be the greatest in the north, and in the south weak high pressure ridges could bring drier interludes.

During the course of the second week pressure may build from the southwest across the southern half of the UK. The north probably remains under an Atlantic flow.
