YELLOW WARNING OF SNOW AND ICE for east Scotland and east England.

Issued 10:50 Sat 31 Jan 2015

Valid from 1300 on Sat 31 Jan to 1200 Sun 1 Feb.

Snow and strong winds will affect parts of northern and then eastern Britain later on Saturday and into Sunday. Heavy snow will affect upland parts of northern Scotland from Saturday afternoon, with accumulations of over 25 cm on some high level routes. At lower levels, there will be a mix of rain, sleet and snow, though snow accumulations of 2-5 cm are possible in places, mainly inland above 150 m. Northerly winds gusting 60-70 mph will give rise to drifting snow and blizzard conditions. Conditions will improve slowly overnight, but further snow showers are likely, even on low ground.

Other eastern areas will see occasional snow showers on Saturday before more persistent rain, sleet and snow spreads southwards overnight, with potential for 2-3 cm of snow at low levels, and 5-10 cm over northern hills where again blizzard conditions are possible.

Icy patches are likely throughout the warning area.

The public should be aware of the risk of disruption due to snow and ice.

YELLOW WARNING OF SNOW AND ICE for Northern Ireland, west Scotland, much of England and Wales

Issued 11:50 on Sat 31

Valid 1440 Sat 31 Jan to 1200 Sun 1 Feb

Sleet and snow showers will continue to affect many area during Saturday and into Sunday. These will be most frequent across northern and Western Scotland, Northern Ireland, West Wales and Devon and Cornwall. Other areas will be largely dry until a more organised area of light snow moves southwards during the early hours of Sunday morning. Accumulations of 1-2 cm are possible, with perhaps 5 cm on some high ground, mainly in the north and west. Icy patches are likely. Strong winds will also gust to around 60 mph along exposed northern and western coasts.

The public should be aware of the risk of disruption due to snow and icy roads.

YELLOW WARNING of SNOW AND ICE for Scotland, Northern Ireland and eastern parts of England.

Issued 11:36 Sat 31 Jan 2015

Valid from 1500 Sun 1 Feb to 2355 Mon 2 Feb.

Further snow showers will affect parts of Scotland and Northern Ireland, and eastern parts of England, later on Sunday and through the whole of Monday, leading to additional accumulations. 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.

This is an update to the Alert issued on Friday to slightly modify the areas covered: Wales and southwestern England are now excluded, while the far southeast of England has been included. This is due to a reorientation of the areas covered in the southwest and southeast to mirror latest forecast probabilities.

YELLOW EARLY WARNING of SNOW for Scotland, Northern Ireland and eastern England.

Snow showers will continue to affect parts of Scotland, Northern Ireland and eastern England during Tuesday, giving icy patches in places. Accumulations of snow are possible in places, even to low levels. The public should be aware of the potential for disruption to travel.

This is an update to the Alert issued on Friday to extend the areas covered to include Northern Ireland, western Scotland and parts of southeast England. This is due to a reorientation of the areas covered to mirror latest forecast probabilities.

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.
