YELLOW WARNING of ICE for all parts of the UK.

Updated 30 January at 11:50

Valid from: 1600 on Friday 30 January

To: 1100 on Saturday 31 January

Icy stretches are likely to form on untreated surfaces on Friday evening, overnight and into Saturday morning. In addition, further accumulation of snow are likely on high ground, especially across the northern half of the yellow area.

The public should be aware of the risk of difficult driving conditions.

YELLOW WARNING of SNOW for Northern Ireland, parts of eastern, western and northern Scotland and also northern England.

Updated 29 January at 11:50

Valid from: 0015 on Saturday 31 January

To: 2345 on Saturday 31 January

Further snow showers will affect parts of Scotland and Northern Ireland from Saturday afternoon and through Sunday leading to some locally large accumulations. These will be associated with strong winds so drifting and temporary blizzard conditions are likely.

The public should be aware of the potential for disruption from these conditions. This alert is likely to be updated in the coming days.

YELLOW EARLY WARNING of SNOW for Northern Ireland, Wales, Scotland, southwest England and coastal fringes of East Anglia and northeast England.

Updated 29 January at 12:25

Valid from: 0015 on Sun 01 January

To: 2345 on Mon 01 February

Further snow showers will affect parts of Scotland and Northern Ireland on Sunday leading to some locally large accumulations and the showers may spread along eastern and western coasts of England and Wales. The showers will be associated with strong winds so drifting and temporary blizzard conditions are possible as well as icy stretches. The public should be aware of the potential for disruption from these conditions.

Snow showers are likely to continue to affect similar areas into Monday bringing further accumulations. Meanwhile, there is a risk of a more persistent spell of rain, sleet and snow affecting Wales, the Midlands and southwest England on Monday. This alert has therefore been extended into Monday and now covers these additional areas, but this is more uncertain and therefore further updates are likely in the coming days.

YELLOW WARNING of SNOW for eastern England and eastern Scotland.

Updated 30 January at 11:55

Valid from: 0015 on Tue 03 February

To: 2345 on Tue 03 February

Snow showers will continue to affect parts of Scotland and England during Tuesday. The showers will mainly be across eastern coastal districts to begin with, but through the course of the day, snow showers will move further inland to affect northeast England, the Midlands and parts of southeast England. Accumulations of snow are possible in places, even to low-levels. The public should be aware of the potential for disruption to travel.

A cold spell on the horizon.

Last week brought some of the coldest weather the UK has seen for some time. With the winter of 2013/2014 being the 5th mildest winter on record (and records began back in 1910!), it's not that surprising that many areas of the UK saw their coldest nights since way back in March 2013. Temperatures dipped to -14 Celsius on Monday across the snow fields of the Highlands of Scotland, and -9 across western Berkshire on Friday morning.

The weekend saw the return of some milder conditions from the west though, and as we head into the start of this week, it looks like temperatures will stay around the average for late January, with some spells of wet and windy weather at times. By late week though, strong northwesterly winds look set to usher in some rather cold weather that will likely last for several days.

Beyond that, a spell of quietr but still rather cold weather is currently thought most likley. A return to broadly westerly winds driving a succession of Atlantic weather systems across the UK is then anticpated as we head into mid-february.

Read on to find out the details...

Dé Luain 26 Eanáir—Dé Domhnaigh 1 Feabhra
Breezy and damp giving way to cold and very windy!

The last week of January will get off to a breezy and damp start as weather fronts and some relatively mild Atlantic air clear away into the continent. This process should leave the remainder of Monday as a fairly dry and bright day for most, save for a few wintry showers that will affect the far northwest of Scotland at times. Conditions will be a little chilly overnight into Tuesday with perhaps a slight frost for rural areas, but during Tuesday another fairly weak Atlantic weather system will be ushered in by brisk westerly winds to bring cloudy, milder conditions with some further patchy rain, chiefly for western hills of the UK.

Cloudy, wet and windy weather is likely to be the order of the day on Wednesday with further Atlantic weather fronts moving in from the west.

By late Wednesday though, the UK weather looks as if it will take on a much colder and windier theme, with strong to gale force northwesterly winds bringing cold air across the UK, and the risk of some periods of snowfall, particularly for Scotland, Northern Ireland and northern areas of England, but possible just about anywhere for a time. There will also likely be an increase in overnight frost risk and icy patches as we move through the remainder of the week and into the weekend. February looks like it will get off to a very cold and windy start!

Dé Luain 2 Feabhra—Dé Domhnaigh 8 Feabhra
Cold through the first week of February.

The cold and strong northwesterly winds that developed towards the end of January look likely to continue through the first week of February, with many areas seeing strong to gale force winds at times, particularly in the north, with even the risk of severe gales around some exposed coastlines of the north and west. Low pressure systems may also be picked up in the northwesterly wind and be driven across the UK, bringing the threat of some spells of snowfall.

By the end of the period, most of the forecasting computer models suggest that an area of high pressure, initially anchored over the mid-Atlantic, will drift eastwards to be positioned over the UK. This process will likely result in a continuation of the cold theme and the associated risk of frosty nights, but the weather is likely to become significantly drier and less windy. Indeed, freezing overnight fog patches are also a likely issue as we head towards the end of first week of the month.

Dé Luain 9 Feabhra—Dé Domhnaigh 22 Feabhra
Returning to a changeable theme.

At the time of writing, the majority of the medium to long range forecasting computer models are suggesting that this period will begin on a changeable note, with a swift return to Atlantic lows crossing the country from the west (a very familiar theme so far this winter of course!). At this range, it is difficult to assign any specific details to the forecast regarding such features. However, it looks most likely that all areas of the UK will experience some wet and windy intervals, with further cold incursions of air from the north or northwest from time to time.

We await further forecast information with interest!

An tseachtain seo chugainn

Will winter bow out on a cold or mild note? Be sure to get the up-to-date medium range forecast details next week.

Réamhaisnéisiú míosúil
Ní furasta an aimsir a thuar níos faide ná seachtain nó mar sin chun tosaigh, fiú don réamhaisnéiseoir is mó taithí. Déantar samhaltáin uimhriúla casta a fháil ón Oifig Meitéareolaíochta agus ón Lárionad Eorpach do Réamhaisnéisí Aimsire Meánraoin (ECMWF) agus déantar iad a rith a lán uaireanta don mhí (agus don séasúr) atá le theacht. Ar an dóigh sin, cruthaítear pictiúr den dóchúlacht go rachadh cineálacha éagsúla aimsire i bhfeidhm ar an RA.
