Will there be any #uksnow next week?
After a warmer than normal October, the weather has slipped into a more typical autumn mode during the beginning of November.
Jack Frost has started to show his chilling face and snowfalls have capped the hills and mountains of Scotland and northern England.
But, as of yet, we really haven’t had a proper reminder that winter is just around the corner. However, that is about to change.
Next week, the wind is likely to change to a northerly direction, opening the gates to allow Arctic air to flood southwards over us, bringing a notable drop in temperature.
Amplified jet stream
The jet stream – the fast-moving ribbon of air five miles above our heads – determines the weather that we experience at the surface.
For the last two weeks, it’s been waving around over or close to the UK, bringing areas of low pressure, wind and rain. However, next week, it’s going to move north of us and wave around with greater amplitude.
This will result in high pressure forming in the mid-Atlantic, which will in turn feed the cold Arctic air towards our shores.
How cold will it be?
Daytime temperatures are likely to be around 2-6C for Scotland and Northern Ireland, with 5-9C for England and Wales.
At night, temperatures will widely fall close to freezing or just below – even in towns and cities, bringing a risk of icy patches.
Will there be any snow?
No doubt, there will be a lot of media speculation as to whether or not there’ll be any snow during the colder weather next week.
At this stage, it is just too early to attempt any kind of detail because the weather computer models are giving mixed messages about precipitation.
Some build high pressure right over the UK which would mean that it stays dry with a greater chance of harder frosts.
However, others keep it just to the west of the UK, which would allow more unsettled weather to affect us.
If this ends up being the case, then there would be a risk of some snow – mainly over the hills and mountains of Scotland, Northern Ireland, northern England and north Wales, but possibly down to lower levels too.
