14 day UK weather forecast

Cold and wintry first week. 

UK outlook issued Thursday 21st January 2021

Week 1

Mixed. Cold for much of the period.

Friday: Central and eastern regions have a mainly dry and bright day. In the north and west there will be wintry showers with some of them falling as snow at low levels. In the afternoon showers may push eastwards across southern counties. Rather cold.

Saturday: Wintry showers continue in the north west. Elsewhere it should be mostly dry and bright but close to the south coast of England there could be some outbreaks of rain, sleet or snow. Cold with frost early and late.

Sunday: Outbreaks of rain, sleet and snow may push across Wales and parts of central and southern England. There is a possibility of accumulations of snow in places, but forecast details are very uncertain. Elsewhere there should be sunny periods but in the north wintry showers continue. Cold.

Monday, Tuesday, Wednesday, Thursday: A cold and dry start is forecast. However, outbreaks of rain push in from the Atlantic quite early in the period and on their leading edge turn to sleet or snow. There is the potential for heavy snow in the north east of Britain. Later on it probably turns mild in the south and temperatures in the north also rise.  

Forecast confidence is high falling to medium.

Week 2

Changeable. Often mild.

All of the country is expected to have wet and possibly windy spells. The largest rain totals are likely to be in the west with more frequent dry periods in the east. At times it could be cold enough for snow in the north, but generally temperatures should often be close to or a little above the seasonal average. Mildest in the south.

Forecast confidence is very low.

Overview

Week 1

The period starts with low pressure centred to the northeast and a cold northwesterly flow covering the UK. It remains in place for several days and there is the possibility of disturbances in the flow pushing across southern counties. Later on weather fronts move in from the Atlantic and push eastwards across the UK. Milder air follows them. 

Week 2

An Atlantic flow remains in place throughout the week. With more of a west or southwesterly element than recently there is the likelihood of milder air filtering across all parts of the UK. Disturbances will be the most active in the west.   

Points of note

Cold weather is predicted to last for much of the first week. There is a risk of sleet or snow, even in parts of the south. During the second week it probably turns milder.
